So I need to programmatically start TunnelBear.exe (a VPN) in C#, and then kill it again. The command for this in cmd is (after going to the directory) TunnelBear.exe --on

This is what I tried in C#:

var process = new Process
{
    StartInfo = new ProcessStartInfo
    {
        FileName = @"C:Program Files (x86)TunnelBearTunnelBear.exe",
        Arguments = @"TunnelBear.exe --on",
        UseShellExecute = false,
        CreateNoWindow = true,
        RedirectStandardOutput = true,
        RedirectStandardInput = true
    }
};
process.Start();
