Compiler Error CS1676

  • Article

Parameter 'number' must be declared with the 'keyword' keyword

This error occurs when the parameter type modifier in an anonymous method is different from that used in the declaration of the delegate you are casting the method to.

The following sample generates CS1676:

// CS1676.cs
delegate void E(ref int i);
class Errors 
{
   static void Main()
   {
      E e = delegate(out int i) { };   // CS1676
      // To resolve, use the following line instead:
      // E e = delegate(ref int i) { };
   }
}
