Compiler Warning (level 2) CS0114

  • Article

'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()
   {
   }
}
