Compiler Error CS0215

The return type of operator True or False must be bool

User-defined true and false operators must have a return type of bool.

The following sample generates CS0215:

C#
// CS0215.cs  
class MyClass  
{  
   public static int operator true (MyClass MyInt)   // CS0215  
   // try the following line instead  
   // public static bool operator true (MyClass MyInt)  
   {  
      return true;  
   }  
  
   public static int operator false (MyClass MyInt)   // CS0215  
   // try the following line instead  
   // public static bool operator false (MyClass MyInt)  
   {  
      return true;  
   }  
  
   public static void Main()  
   {  
   }  
}
