Compiler Warning (level 2) CS0114

'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()  
   {  
   }  
}
