Question

I would like to start a new process but I need it to use a different folder for AppData. In a windows batch file you can do it like this:

set APPDATA=C:\MyDataFolder

It will set the AppData for any program launched in the batch file, so how can I do this in C#?

Answer 1

You can add environment variables to the ProcessStartInfo:

ProcessStartInfo p = new ProcessStartInfo("some_executable.exe");
p.UseShellExecute = false; // apparently required when adding environment variables
p.EnvironmentVariables.Add("APPDATA", @"C:\MyDataFolder");
Process.Start(p);
