Reading a file path from text file with environment variable in C#

I am trying to read a text file with file paths, but the problem I'm having is I want to add environment variable in it with the specific file path, how should I achieve that? I tried to do %example123%+\XML\sample.xml but c# is not recognizing the variable instead it's reading it as a String.

Two options, per your example:

System.Environment.GetEnvironmentVariable("example123") + @"\XML\sample.xml"

or

System.Environment.ExpandEnvironmentVariables(@"%example123%\XML\sample.xml")

Something to note from this question is that Visual Studio must be restarted before the variable is recognized if you have set the variable using System.Environment.SetEnvironmentVariable().

These two methods should help you in getting or setting environment variables.

System.Environment.GetEnvironmentVariable ()

and

System.Environment.SetEnvironmentVariable()

Either use them in your path variable or declare it separately, whichever is more readable.

Note: When using the SetEnvironmentVariable() sometimes you would have to restart visual studio to be able to read the environment variable after creating it.

Here's an example for %AppData%

System.Environment.GetEnvironmentVariable("AppData");
