Could not find any resources appropriate for the specified culture or the neutral culture

问题

I have two ASP.NET Web projects (ProjectA and ProjectB). When class in ProjectA is instantiating a class of ProjectB which uses a resource file Blah.resx, I get this error:

An exception of type \'System.Resources.MissingManifestResourceException\' occurred in mscorlib.dll but was not handled in user code.

Could not find any resources appropriate for the specified culture or the neutral culture. Make sure \"Resources.Blah.resources\" was correctly embedded or linked into assembly \"App_GlobalResources.sn_flri6\" at compile time, or that all the satellite assemblies required are loadable and fully signed.

Whats causing this?

There is an article on Microsoft\'s site about this http://support.microsoft.com/kb/318603 which suggests:

To resolve this problem, move all of the other class definitions so that they appear after the form\'s class definition.

This is a solution for Windows Forms project, I\'m not sure if that also applies to Web projects.

I just hit this same exception in a WPF project. The issue occurred within an assembly that we recently moved to another namespace (ProblemAssembly.Support to ProblemAssembly.Controls). The exception was happening when trying to access resources from a second resource file that exists in the assembly.

Turns out the additional resource file did not properly move references from the old namespace name to the new namespace name.

In the designer.cs for the resource file, there is a static property to get the ResourceManager. Within that getter, the string was still referring the old namespace. Once correcting it to the new namespace, the problem was resolved:

global::System.Resources.ResourceManager temp = 
     new global::System.Resources.ResourceManager(
          "ProblemAssembly.Support.Properties.Stuff", typeof(Stuff).Assembly);

should have been:

global::System.Resources.ResourceManager temp = 
     new global::System.Resources.ResourceManager(
          "ProblemAssembly.Controls.Properties.Stuff", typeof(Stuff).Assembly);

Hope this helps the next person.

I solved the problem like this:

Right click on your ResourceFile
Change the "Build Action" property Compile to "Embedded Resource"
Then build and run

It works perfectly.

回答3:

When I tried sharing a resource.resx file from one C# project with another C# project, I got this problem. The suggestion on moving the Form class to the beginning of its file wasn't appropriate. This is how I solved it. You essentially use a link from the second project to the first, then enable regeneration of the resource.designer.cs file.

Delete the second project's Properties/Resources.resx file
Add the first project's Properties/Resources.resx file as a LINK to the Properties folder in the second project. Don't add it to the root level of the project.
Don't add the first project's Properties/Resources.designer.cs!
On the properties of the second project's Resources.resx, add ResXFileCodeGenerator as the CustomTool
Right click on the Resources.resx and select "Run Custom Tool". This will generate a new designer.cs file.

Note: I would avoid editing the resource.designer.cs file, as this is autogenerated.

回答4:

In my case a series of badly thought global text replacements had inadvertently changed this line in the resource designer cs file.

Since the namespace in that argument did not match the namespace of the class anymore, the application got confused at run time.

Check that the namespace of the designer matches the string argument in that line.

回答5:

It happens because the *.resх is excluded from migration.

Right click on your ResourceFile
Click on the menu item "Include in project"

回答6:

I found that deleting the designer.cs file, excluding the resx file from the project and then re-including it often fixed this kind of issue, following a namespace refactoring (as per CFinck's answer)

回答7:

No-one seems to have mentioned this solution. Obvious really - but tripped me over for a moment...

The default access modifier for a new resources file is Internal (or Friend in VB.Net.) Make sure you change this to Public

(in the resx designer there is a dropdown at the top for the access modifier)

回答8:

Sibi Elangos answer alone was not sufficient for me, so I had to

Right click on your ResourceFile
Change the "Build Action" property
Compile to "Embedded Resource"
Build and deploy

This will generate an App_GlobalResources in your /bin folder, now copy that folder also to the root of the web application

回答9:

In my case, the issue caused by defining class the wrong way:

namespace MyBuggyWorld
{
    public class BackendObject //This hack broke the VS 2017 winform designer and resources linker!
    {
        public TcpClient ActiveClient { get; set; }
        public BackgroundWorker ActiveWorker { get; set; }
    }
    public partial class FormMain : Form
    {
    }
}

After Reallocating BackendObject to the end (better to separate file), doing project clean + rebuild resolved the issue.

回答10:

I resolved this by going to the project where my resources file was saved, scrolling down to its ItemGroup and adding a logical name that corresponded to the path the compiler expected.

My EmbeddedResource looked like this:

   <ItemGroup>
    <EmbeddedResource Update="Properties\TextResources.resx">
      <Generator>PublicResXFileCodeGenerator</Generator>
      <LastGenOutput>TextResources.Designer.cs</LastGenOutput>
    </EmbeddedResource>
  </ItemGroup>

Now it looks like this

  <ItemGroup>
    <EmbeddedResource Update="Properties\TextResources.resx">
      <Generator>PublicResXFileCodeGenerator</Generator>
      <LastGenOutput>TextResources.Designer.cs</LastGenOutput>
      <LogicalName>MyProject.Properties.Resources.resources</LogicalName>
    </EmbeddedResource>
  </ItemGroup>

回答11:

One approach would be to put the shared classes/resources in a separate class library project and refer them in both the web sites.

回答12:

Thanks @CFinck ! Just to add a tip to others : I changed the ResourceManager line with this :

New Global.System.Resources.ResourceManager(Reflection.Assembly.GetCallingAssembly.GetName.Name & ".CommonNameOf.Resources", Reflection.Assembly.GetCallingAssembly())

I'm in vb.net but I think in C# the only difference would be + instead of & to concatenate strings.

This way I can use the same linked assembly files in two similar projects that share the resources.

回答13:

As far as this case is concerned check if the assembly containing resources has the default namespace set to the same text (Project->Properties->Default namespace; in VS) Check as well if the resx file has a property BuildAction set to "Embedded resource" Enjoy... ;)

回答14:

This error is also raised by Dotfuscation, since a resx designer file relies on reflection. If you are using Dotfuscator it will break your resx files. You must always add them as an exclusion from the obfuscation process.

回答15:

When we were using

HttpContext.GetGlobalResourceObject()

It would generate that error unless we wrapped that call inside a try/catch statement.

回答16:

I have a WinForms application with a single project in the solution.
Targeting .NET Framework 4.0
Using SharpDevelop 4.3 as my IDE

Sounds silly, but I happened to have the Logical Name property set to "Resources" on my "Resources.resx" file. Once I cleared that property, all works hunky-dory.

Normally, when you add random files as EmbeddedResource, you generally want to set the Logical Name to something reasonable, for some reason, I did the same on the Resources.resx file and that screwed it all up...

Hope this helps someone.

回答17:

For me the problem was copying .resx files and associated .cs files from one project to another. Both projects had the same namespace so that wasn't the problem.

Finally solved it when I noticed in Solution Explorer that in the original project the .resx files were dependent on the .cs files:

MyResource.cs
|_ MyResource.resx

While in the copied project the .cs files was dependent on the .resx files:

MyResource.resx
|_ MyResource.cs

It turned out that in the second project somehow the .resx files had been set to auto-generate the .cs files. The auto-generated .cs files were overwriting the .cs files copied from the original project.

To fix the problem edit the properties of each .resx file in the copied project. The Custom Tool property will be set to something like ResXFileCodeGenerator. Clear the Custom Tool property of the .resx file. You will need to re-copy the .cs file from the original project as it will have been overwritten by the auto-generated file.

回答18:

Just because you are referencing Project B's DLL doesn't mean that the Resource Manager of Project A is aware of Project B's App_GlobalResources directory.

Are you using web site projects or web application projects? In the latter, Visual Studio should allow you to link source code files (not sure about the former, I've never used them). This is a little-know but useful feature, which is described here. That way, you can link the Project B resource files into Project A.

回答19:

In my case these lines of code added to Web.config helped a lot:

<system.web>
     ...
    <globalization uiCulture="cs" culture="cs-CZ" />
     ...
<system.web>

Together with Build action: Embedded Resource and Custom Tool: PublicResXFileCodeGenerator.

回答20:

Double Click properties in Application section check Assembly name and default namespace are the same

回答21:

In my case I had placed a new class on top of a Windows form, within the same file.

Moving the newly added class out of that file fixed the problem.

回答22:

This can be caused by mismatched namespaces. The second from top answer (Sibi Elango's) says to right-click the resx file, and change Build option to EmbeddedResource, but I had already done that and still had the error. The top answer (CFinck's) notes a way of fixing this via manually editing files, however, I had this problem in MonoDevelop, and had to set the default namespace to the same as the cs file which was calling for the resource (the file which contained code such as the code below)...

this.Icon = ((System.Drawing.Icon)(resources.GetObject("$this.Icon")));

After setting the default namespace via the GUI, the line above no longer caused an exception.

回答23:

I was also facing the same issue, tried all the solutions mentioned in the answer but none seemed to work. Turned out that during the checkin of code to TFS. TFS did not checkin the Resx file it only checked in the designer file. So all other developers were facing this issue while running on their machines. Checking in the resx file manually did the trick

回答24:

This can also occur when putting a class above the main winform class (Form1, for example) You can see this when you look at the design, as it fails to be rendered.

回答25:

Yet another cause: if your namespace has a hyphen ("-"), then it will build and run correctly, but the resource won't be accessible. Namespaces (identifiers) aren't supposed to have hyphens, but this doesn't appear to be enforced anywhere except in loading resources. This has burned me twice over the decade.

回答26:

Another thing to check is if you have LogicalName or ManifestResourceName defined on the EmbeddedResource. Make sure those are defined appropriately if your project file is using them as they can cause the resources to live under a name you are not expecting.

回答27:

Just another case. I copied a solution with two projects and renamed them partially in the Windows explorer (folder names, .sln and .csproj file names) and partially with a massive Find & Replace action in Visual Studio (namespaces etc.). Nevertheless the exception stated by the OP still occurred. I found out that the Assembly and Namespace names were still old.

Although the project and everything else was already named OfficeStyle the Assembly name and Default namespace were still named Linckus.

After this correction everything worked fine again, compile and run time :)
