Load a Specific class from dll in C#

Question

I want to load only some classes from a given dll. The problem is the following:

I have the following of dll files.

Dll 1:

Namespace:

• Class 1
• Class 2

Dll 2:

Namespace:

• Class 2
• Class 3

As shown in the example above, it is possible and likely to happen that I have 2 or even more dlls with the same classes in it. (Note that the namespaces are the same)

Now I thought of the following:

• Open a dll in a Temp AppDomain
• Check which classes we do not know
• Move needed classes to Standard Appdomain
• Unload Temp Appdomain

Is there any way to do something like that?

Answer 1

You have two different dll file. So You can import two different dll file into you C# project. For example first dll file's name is "File1" and second dll file's name is "File2"

const string file1_Dll_Path = @"File1.dll";
const string file2_DllPath = @"File2.dll";
[DllImport(file2_DllPath, CallingConvention = CallingConvention.Cdecl)]
    public static extern int YOURFUNCTIONINFILE2DLL();
[DllImport(file1_Dll_Path, CallingConvention = CallingConvention.Cdecl)]
    public static extern void YOURFUNCTIONINFILE1DLL();

Note: Don't forget adding "unsafe" your C# Form. Like this

unsafe public partial class FORMNAME : Form
