c# dllimport question

I am iporting a method from an external dll and have the following code:

[DllImport("test.dll", CharSet = CharSet.Unicode, SetLastError = true)]
    public static extern TabPage CreateGUI();

and to call this:

tabControl1.TabPages.Add(CreateGUI());

I get the error saying that CreateGui cannot be located within the dll. The CreateGui method has been declared public and static within the dll? Anybody any ideas?

Thanks.

If the method returns a TabPage it is a .NET method, hence it is a .NET Assembly. Then you should not import it with DllImport, but add the dll as a reference in your project.

Edit:
If you want to load a .NET Assembly dynamically you need to load it with Assembly.LoadFile and then find your types with Assembly.GetTypes.
