C# - Param Arrays
At times, while declaring a method, you are not sure of the number of arguments passed as a parameter. C# param arrays (or parameter arrays) come into help at such times.
The following example demonstrates this −
using System; namespace ArrayApplication { class ParamArray { public int AddElements(params int[] arr) { int sum = 0; foreach (int i in arr) { sum += i; } return sum; } } class TestClass { static void Main(string[] args) { ParamArray app = new ParamArray(); int sum = app.AddElements(512, 720, 250, 567, 889); Console.WriteLine("The sum is: {0}", sum); Console.ReadKey(); } } }
When the above code is compiled and executed, it produces the following result −
The sum is: 2938
