Named parameters were added in C# 4.0.

<lang csharp>using System;

namespace NamedParams

{

class Program

{

static void AddWidget(string parent, float x = 0, float y = 0, string text = "Default")

{

Console.WriteLine("parent = {0}, x = {1}, y = {2}, text = {3}", parent, x, y, text);

}

static void Main(string[] args)

{

AddWidget("root", 320, 240, "First");

AddWidget("root", text: "Origin");

AddWidget("root", x: 500);

AddWidget("root", y: 500, text: "Footer");

}

}

}</lang>

Output:

<pre>parent = root, x = 320, y = 240, text = First

parent = root, x = 0, y = 0, text = Origin

parent = root, x = 500, y = 0, text = Default

parent = root, x = 0, y = 500, text = Footer</pre>
