How to add member variable to an interface in c#
- by Nassign
I know this may be basic but I cannot seem to add a member variable to an interface.
I tried inheriting the interface to an abstract class and add member variable to the abstract class but it still does not work. Here is my code:
public interface IBase {
void AddData();
void DeleteData();
}
public abstract class AbstractBase : IBase {
string ErrorMessage;
abstract AddData();
abstract DeleteData();
}
