how to handle spaces in file path if the folder contains the space?

public static void launchProcess(string processName, string arguments, out string output)
{
    Process p = new Process
    {
        StartInfo = { UseShellExecute = false, RedirectStandardOutput = true, FileName = processName, Arguments = arguments }
    };

    p.Start();
    output = p.StandardOutput.ReadToEnd();
    p.WaitForExit();

}

And if my arguments contains the file names like:

D:\Visual Studio Projects\ProjectOnTFS\ProjectOnTFS

Then I get the error:
