Compiler Error CS1554

Declaration is not valid; use '<type> operator op (...' instead

The return type of an overloaded operator must appear before the operator keyword.

The following sample generates CS1554:

// CS1554.cs  
class MyClass  
{  
   public static operator ++ MyClass (MyClass f)    // CS1554  
   // try the following line instead  
   // public static MyClass operator ++ (MyClass f)  
   {  
      return new MyClass ();  
   }  
  
   public static void Main()  
   {  
   }  
}
