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, and Knowing When to Use Override and New Keywords.

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()
        {
        }
    }
}
