Compiler Error CS1534

Overloaded binary operator 'operator' only takes two parameters

The definition of a binary overloadable operator must take two parameters.

The following sample generates CS1534:

class MyClass {
   public static MyClass operator - (MyClass MC1, MyClass MC2, MyClass MC3) {   // CS1534
   // try the following line instead
   // public static MyClass operator - (MyClass MC1, MyClass MC2) {
      return new MyClass();
   }
   public static int Main() {
      return 1;
   }
}
