Compiler Error CS0539

'member' in explicit interface declaration is not a member of interface

An attempt was made to explicitly declare an interface member that does not exist. You should either delete the declaration or change it so that it refers to a valid interface member.

The following sample generates CS0539:

// CS0539.cs  
namespace x  
{  
   interface I  
   {  
      void m();  
   }  
  
   public class clx : I  
   {  
      void I.x()   // CS0539  
      {  
      }  
  
      public static int Main()  
      {  
         return 0;  
      }  
   }  
}
