Asp.Net Mvc 5 image not displaying

问题

I have same images in Content and Views folders. I am trying to display images as below:

<img src="~/Content/Images/download.png" alt="Content folder" />
<br />
<br />
<img src="~/Views/Home/download.png" alt="Views folder" />
<br />

The image in Content folder displays successfully but the one in Views folder doesn't display and gives below error:

Failed to load resource: the server responded with a status of 404 (Not Found)

But actually, the resource is there. Here are my folders:

Could you please tell me which point I am doing wrong? I am using MVC 5 with razor engine and Visual Studio 2015 community edition.

Unless you changed the default configuration, folder Views contains file Web.config that has settings for restricting access to files in this folder:

<system.webServer>
    <handlers>
      <remove name="BlockViewHandler"/>
      <add name="BlockViewHandler" path="*" verb="*" preCondition="integratedMode" 
           type="System.Web.HttpNotFoundHandler" />
    </handlers>
</system.webServer>

So you can either remove this handler (which is not recommended for security purposes), or move your static files to some other folder, e.g. Content.

Its because of the inbuilt security of ASP MVC to protect your views being accessed directly. Check removing 'BlockViewHandler' handler entry from ~/Views/web.config

My advice is to move image to 'Content' folder and keep 'Views' folder clean.

回答3:

Any MVC Version not allow to load other resource except html from Views folder. Because when you call a URL it waiting for text/html content type and because of that image inside main Views folder not able to render in page.

for better information please check file header request and response in browser (development tool/F12) network tab.

Response of image from Views:

Response of image from content folder:

In .net core 3 you will also need this below line in startup.cs

app.UseStaticFiles(new StaticFileOptions
            {
                FileProvider = new PhysicalFileProvider(
                Path.Combine(Directory.GetCurrentDirectory(), @"wwwroot\images")),
                RequestPath = "/wwwroot/images"
            });
