Placing Structs and Enums in Interface - should i?

[Chua Wen Ching]

Hi there,

I am wondering when i had a class that extends an interface (currently in my
interface i only had methods), but should i also extend Struct, Enum or even
P/Invoke methods?

If it can, how do i code struct or enum or p/invoke in an interface???

just say my struct is:

[StructLayout(LayoutKind.Sequential)]
public struct TestA
{
public byte ab;
public byte[] bc;
}

public enum TestB : Byte
{
num1 = 0,
num2 = 10
};

[DllImport("somedll.dll")]
public static extern int TestC();

Any idea, please?

Thanks.
