Environment variables in C#

I was using an environment variable which was named ABC and had a value of C:/ABC.
In my code I used @"%ABC%/file.txt" for the file path where I had created a folder on the C drive called ABC containing a file called file.txt.

However this does not recognise the environment variable.

Is there any way to make this short-cut work or do I need to manually read the System Environment variable into a separate Environment variable using Environment.GetEnvironmentVariable Method (String) within Visual Studio?

Try 

 string _yourpath = Environment.ExpandEnvironmentVariables(@"%ABC%/file.txt");

You can do this:

string path = Environment.ExpandEnvironmentVariables(@"%ABC%/file.txt");

There is an aptly named Environment.ExpandEnvironmentVariables that should do the work for you.
