Error Message
'function1' hides inherited member 'function2'. To make the current method override that implementation, add the override keyword. Otherwise add the new keyword.
A declaration in a class conflicts with a declaration in a base class such that the base class member will be hidden.
For more information, see base.
The following sample generates CS0114:
// CS0114.cs
// compile with: /W:2 /warnaserror
abstract public class clx
{
public abstract void f();
}
public class cly : clx
{
public void f() // CS0114, hides base class member
// try the following line instead
// override public void f()
{
}
public static void Main()
{
}
}
