As you have so aptly mentioned in the subject of this question, is the namespace included in the web page. If they are separate dll's, is the dll reference added?

Make sure the following things:

1. The class (cs file) inside the App_Code folder compiles.
2. The class is public.
3. If the class has a namespace, make sure it is imported in the codebehind file with the "using" statement.
4. Make sure the methods of the class file are public.

Hopefully, your problem will be resolved.

Thanks ,
The class was internal and when i make it public it solve the problem but,
But i have desktop application the class is internal and no problem.
My question is that why in desktop application but in web application there is problem.
thanks again

If a class is "internal", this class will be visible only within the assembly and no external assembly will not be able to access the class. Now, if you write any class within the "App_Code" folder, a separate assembly is created and compiled automatically. So, in this case, the class wasn't visible from the codebehind class.

In your desktop application, I guess the class was within a single assembly (Not written within a separate class library) and hence you were able to access it.

Cheers.

Thanks for your answer,
I am understand now that if you write any class within the "App_Code" folder, a separate assembly is created and compiled automatically.
Thank youuuuuuuuuu
