Compiler Error CS0231

A params parameter list or the __arglist parameter must not have any following arguments

The params keyword must be the last parameter declared for a method.

The following sample generates CS0231:

using System;
public class MyClass {

   public static void UseParams(int AnInt, params int[] list, int i) {   // CS0231
   // try the following line instead
   // public static void UseParams(int AnInt, params int[] list) {
      for ( int i = 0 ; i < list.Length ; i++ )
         Console.WriteLine(list[i]);
      Console.WriteLine();
   }

   public static void UseArglist(int AnInt, char AChar, __arglist) {
      Console.WriteLine(AnInt);
      Console.WriteLine(AChar);

      ArgIterator ai = new ArgIterator(__arglist);
   
      while (ai.GetRemainingCount() > 0)
         Console.WriteLine(__refvalue(ai.GetNextArg(), int));
   }

   public static void Main() {
      UseParams(1, 2, 3);
      UseArglist(20, 'b', __arglist(1, 2, 3));
   }
}
