Compiler Error CS0115

'function' : no suitable method found to override

A method was marked as an override, but the compiler found no method to override. For more information, see override (C# Reference), and Knowing When to Use Override and New Keywords (C# Programming Guide).

Example

The following sample generates CS0115. You can resolve CS0115 in one of two ways:

• Remove the override keyword from the method in MyClass2.

• Use MyClass1 as a base class for MyClass2.

// CS0115.cs
namespace MyNamespace
{
    abstract public class MyClass1
    {
        public abstract int f();
    }

    abstract public class MyClass2
    {
        public override int f()   // CS0115
        {
            return 0;
        }

        public static void Main()
        {
        }
    }
}
