Abhay Shanker · Answer

The params keyword is specified before the array type declaration in a parameter list in a method. You can use the params keyword on instance or static methods. It must be the last argument in the parameter list static void Main() { // // Call params method with one to four integer constant parameters. // int sum1 = SumParameters(1); int sum2 = SumParameters(1 2); int sum3 = SumParameters(3 3 3); int sum4 = SumParameters(2 2 2 2); // // Write results of the method invocations. // Console.WriteLine(sum1); Console.WriteLine(sum2); Console.WriteLine(sum3); Console.WriteLine(sum4); } static int SumParameters(params int[] values) { // // Loop through and sum the integers in the array. // int total = 0; foreach (int value in values) { total += value; } return total; }
