Arguments to Thread

[sunburnt]

How can I pass arguments to the function I want to run in a new thread? I'm currently working around it like this, but could cause problems if the same instance of my class runs the procedure twice in a row.

//....

private string sTempFile;
private Process pTempProc;

//....

private void KillFile()
{
    //wait for the process to exit and kill the file.
    //i want to pass a process and a filename
    //to this function when i start it in its own thread.
    pTempProc.WaitForExit();
    File.Delete(sTempFile);
}

public void Execute(string sFileName, bool WaitAndCleanup)
{
    sTempFile = this.Unpack(sFileName);
    pTempProc = new Process();

    pTempProc.StartInfo = new ProcessStartInfo(sTempFile);

    pTempProc.Start();

    if (WaitAndCleanup) 
    {
        Thread th = new Thread(new ThreadStart( KillFile ) );
        th.Start();
    }
    return;
}
