Can you create a function in C# which can accept varying number of arguments?

By using the params keyword, you can specify a method parameter that takes a variable number of arguments. No additional parameters are permitted after the params keyword in a method declaration, and only one params keyword is permitted in a method declaration. The declared type of the params parameter must be a single-dimensional array.

public static void UseParams(params int[] list) {
 for (int i = 0; i < list.Length; i++) {
  Console.Write(list[i] + " ");
 }
 Console.WriteLine();
}

public static void UseParams2(params object[] list) {
 for (int i = 0; i < list.Length; i++) {
  Console.Write(list[i] + " ");
 }
 Console.WriteLine();
}

// usage
UseParams(1, 2, 3, 4);
UseParams2(1, 'a', "test");
