{
    string contents = sr.ReadToEnd();
    using (StreamWriter sw = new StreamWriter("C:\\Work\\checksnapshot.properties"))
    {
        if (contents.Contains(args[0]))
        {
            sw.WriteLine("SASE= 1");
        }
        else
        {
            sw.WriteLine("SASE= 0");
        }
    }
}

    {
        if (contents.Contains(args[0]))

    using (StreamWriter sw = new StreamWriter("C:\\Work\\checksnapshot.properties"))
    {
        if (contents.Contains(args[0]))
        {
            sw.WriteLine("mobile= 1");
        }
