Compiler Error CS1593 

Error Message

Delegate 'del' does not take 'number' arguments

The number of arguments passed to a delegate invocation does not agree with the number of parameters in the delegate declaration.

The following sample generates CS1593:

// CS1593.cs
using System;
delegate string func(int i);   // declare delegate

class a
   public static void Main()
      func dt = new func(z);

   public static string z(int j)
      return j.ToString();

   public static void x(func hello)
      hello(8, 9);   // CS1593
      // try the following line instead
      // hello(8);
