C#–Using static

While writing my blog post yesterday about class aliases, I was reading through the documentation about the using keyword and noticed another feature I almost forgot: ‘using static’.

Through ‘using static’ you can import static members of types directly into the current scope. This can safe you from some extra typing work if you need a specific static class over and over again.

An example:

	using System;
	class Program
	{
	static void Main()
	{
	Console.WriteLine("Hello world!");
	Console.WriteLine("Another message");
	Console.ReadKey();
	}
	}

In the code above I have to repeat the ‘Console’ static class for each call. Now let’s rewrite this example with the help of ‘using static’:

	using static System.Console;
	class Program
	{
	static void Main()
	{
	WriteLine("Hello world!");
	WriteLine("Another message");
	ReadKey();
	}
	}
