You can start your application again with elevated permission and have some check at the application's start to see if this is the case. Here's an example: (Be careful not to get into an endless loop of the application starting itself.)

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
        string[] args = Environment.GetCommandLineArgs();
        if (args.Length > 1 && args[1] == "-e") Text = "Elevated";
    }

    private void button1_Click(object sender, EventArgs e)
    {
        Process process = new Process
        {
            StartInfo = new ProcessStartInfo
            {
                FileName = Application.ExecutablePath,
                Arguments = "-e",
                Verb = "runas",//-Admin.
            }
        };
        process.Start();
    }
}

I agree, though, that storing information in "C:" is probably not a good idea. You can try someplace like: Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData).
