--- title: Indeterminate parameters --- # Indeterminate parameters Let's imagine we need to write a method where the number of parameters are variable. How can we do that? Well, C# (and other languages) has an easy way to do so; by using the `params` keyword on a method's parameter we can call that method with a variable number of parameters. ## Example ``` public static void Main (string[] args) { // Call PrintParams with 3 parameters PrintParams(1, 2, 3); // Call PrintParams with 1 parameter PrintParams(4); } public static void PrintParams(params int[] values) { // Iterate through parameters for (int i = 0; i < values.Length; i++) { Console.WriteLine("Parameter {0} is {1}", i, values[i]); } } ``` ## Output: ``` > Parameter 0 is 1 > Parameter 1 is 2 > Parameter 2 is 3 > Parameter 0 is 4 ```
