Question

Long time lurker, first time poster here.

My question is:

Using C# 2.0, is there a way to associate am image with a class/type such that I don’t have to create an instance of the class just to get the image object from that class?

What I am trying to do is scan all the .dlls in my application and construct a list of classes and corresponding attributes. I have this working great, and now I want to somehow associate an image with each class so that I can display a list of classes and have a unique image for each.

I’ve tried searching SO and the internet for an answer, but can’t find anything definite. Any help would be greatly appreciated.

Thanks,

Kyle

Figured out how to do it using ideas here and there.

1. Mark the image as an EmbeddedResource.

2. Create an attribute for specifying the image name.

3. Once the image name attribute is read, use the following to locate the image resource inside the assembly where the class was declared:

   string[] all = info.Type.Assembly.GetManifestResourceNames();
   
   foreach (string resourceStr in all)
   {
     if (!String.IsNullOrEmpty(resourceStr) && resourceStr.EndsWith(String.Format(".{0}", iconName), true, CultureInfo.CurrentCulture))
     {
       Stream file = info.Type.Assembly.GetManifestResourceStream(resourceStr);
   
       if (file != null)
       {
         info.Icon = Image.FromStream(file);
       }
     }
   }
