问题 The Scenario: LUNCHER.exe : a WPF Application >> Build 32bit , .Net 4.5.1 , location= D:\ LOADED.exe : another WPF Application >> Build 32bit , .Net 4.5.1, location= D:\ I'm owner of both assembly (both application and thair sources) Now, i want load the LOADED.exe [and its resources such as images dlls and...) as a Byte array to the memory and execute it, then remove LOADED.exe and its resources from hard disk. In the first step i'm trying to just load the LOADED.exe file to memory and

问题 I am trying to load a DLL file that has been copied into a byte array into a new AppDomain. The DLL does contain references to things like Windows.Forms and other dlls. Are those the ones failing to load? If so how do you pre-load them for that specific domain? AppDomainSetup Setup = new AppDomainSetup(); Setup.ApplicationBase = AppDomain.CurrentDomain.BaseDirectory; Setup.ApplicationName = "Plugin_" + DLLName + "" + PluginManager.PluginList.Count; AppDomain Domain = AppDomain.CreateDomain(

问题 In my window forms application, I create a Appdomain say sandBox. In this sandbox i excute some code Say TestMethod from TestAppdomain Class. This class is in Test.dll which is not loaded in the current appdomain (Default appdomain). Now while executing TestMethod some exception occurs, then I want the sandbox domain to be unloaded and since AppDOmain provide Isolotion my Default Appdomain shoud not be affected. But As i read over the internet i guess this is not possible.But could some one

问题 Somehow I assumed that delegates passed to another AppDomain would turn into a proxy as if it were an object derived from MarshalByRefObject . Unfortunately, it seems they don’t. Let’s say in my code I have a class MyClass like this: [Serializable] public sealed class MyClass { public Func<Input, Output> SomeDelegate; } [Serializable] public sealed class Input { ... } [Serializable] public sealed class Output { ... } Now I need to pass an instance of MyClass to another AppDomain. The problem

问题 I need to dynamically create a .NET 2.0 compatible assembly from within my .NET 4.0 process. Currently it is achieved with this: AssemblyBuilder ab = AppDomain.CurrentDomain.DefineDynamicAssembly(...) ModuleBuilder mb = assemblyBuilder.DefineDynamicModule(...); But unfortuntely all dll's produced are .NET 4.0 (inherited from my 4.0 process) which doesn't work with my other .NET 2.0 processes. Any idea how 2 different CLR versioned AppDomains can co-exist in the same process? 回答1: Have a look

问题 I have relatively simple application, but warm (second, etc.) start-up time is awful 3-5 seconds. Profiler (VS2010, CPU Sampling) shows that more than 80% of time is spent in Application.RunInternal (~40%) and XamlRader.LoadBaml (~40%) functions. The root of the problem is that Window is created in non-default AppDomain. If I move Window creation to default AppDomain or give AppDomain unrestricted permission set everything is as fast as expected. I'm testing on: Windows Seven x64 .Net 4.0 4Gb

问题 after doing some research it seems that AppDomains are not really a tool for building a hosting server. From my understanding, the hosting server will still crash if there is an unhandled exception in a created AppDomain (if the exception is thrown from a thread in the created AppDomain). So in that case if the hosting server hosts a service which leaks exceptions this will bring down the default AppDomain as well. So I guess from a server architecture point-of-view there is nothing better

问题 I have some code that dynamically compiles a Razor templates into an Assembly which I execute with a set of permissions (no access to files, etc). This works on our development computers and on our test server (Windows 2008 IIS7 x64 .NET 4). But on our production server (Same spec) it gives the error: "Loading this assembly would produce a different grant set from other instances. (Exception from HRESULT: 0x80131401)" Here is the code: - public static SandboxContext Create(string

问题 In order to store the state of processes when an error occured, I would like to list all (custom) data stored in AppDomain (by SetData). The LocalStore property is private and AppDomain class not inheritable. Is there any way to enumerate those data ? 回答1: AppDomain domain = AppDomain.CurrentDomain; domain.SetData("testKey", "testValue"); FieldInfo[] fieldInfoArr = domain.GetType().GetFields(BindingFlags.NonPublic | BindingFlags.Instance); foreach (FieldInfo fieldInfo in fieldInfoArr) { if

问题 I have an unmanaged C++ DLL that my .NET application uses via p/invoke. The method that I need from this DLL is fairly time consuming and I would like to parallelize the method calls. The problem is that it uses a bunch of statics and globals, so it is not thread-safe (and can't be changed). My plan was to overcome this non-thread-safe issue by calling the unmanaged DLL from multiple AppDomains in parallel. I can call the unmanaged code from the multiple AppDomains without any problems as
