Compiler Error CS1553

Declaration is not valid; use 'modifier operator <dest-type> (...' instead

The return type for a conversion operator must immediately precede the parameter list, and modifier is either implicit or explicit.

The following sample generates CS1553:

// CS1553.cs  
class MyClass  
{  
   public static int implicit operator (MyClass f)   // CS1553  
   // try the following line instead  
   // public static implicit operator int (MyClass f)  
   {  
      return 6;  
   }  
  
   public static void Main()  
   {  
   }  
}
