Compiler Error CS1501

No overload for method 'method' takes 'number' arguments

A call was made to a class method, but there is no form of the method that takes the necessary number of arguments.

CS1501 could occur when you allocate memory for a delegate; you must also specify the name of the method that the delegate represents.

The following sample generates CS1501:

public class a {
   /*
   declare the following constructor to resolve this CS1501
   public a(int i) {
   }
   */
   public static void Main() {
      a aa = new a(2);   // CS1501
   }
}

The following sample generates CS1501:

using System;
delegate string func(int i);   // declare the delegate

class a {
   static func dt;   // class member-field of the declared delegate type
   public static void Main() {
      // dt = new func();   // CS1531
      // try the following line instead
      dt = new func(z);   // this works
      x(dt);
   }

   public static string z(int j) {
      Console.WriteLine(j);
      return j.ToString();
   }

   public static void x(func hello) {
      hello(8);
   }
}
