Environment.GetEnvironmentVariable(variable, target);

target can be:
EnvironmentVariableTarget.Process,
EnvironmentVariableTarget.User,
EnvironmentVariableTarget.Machine.

It's the same method, just set the second parameter to be User as:

System.Environment.GetEnvironmentVariable("varName", EnvironmentVariableTarget.User);

I am trying to get username but GetEnvironmentVariable returns null: System.Environment.GetEnvironmentVariable("username", EnvironmentVariableTarget.User); – James Nov 07 '16 at 13:43

@James I think you're looking for `System.Environment.UserName`. – Hans Olsson Nov 07 '16 at 14:10

Use second overload of GetEnvironmentVariable which let's you specify EnvironmentVariableTarget.
