How to use system\environment variables in .NET string?

I have path variable which I got from my appsettings:

var path="%TEMP%\myapplication\data";

I am trying to use it in Directory.CreateDirectory(path) method. But I got new folder in my application bin folder instead of C:\Users\Evgeny\AppData\Local\Temp\myapplication\data.

Should I replace %TEMP% manually?

Use System.Environment.ExpandEnvironmentVariables like so:

String concretePath = Environment.ExpandEnvironmentVariables(@"%TEMP%\myapplication\data");
