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;
}

Which function do you want to pass the arguments to?

What I would do is build a class that has this method, and the properties to set for the variables needed.

Now, you create an instance of the class, set the properties, and start it's method on its own thread. Then when you need to make another thread, you just create another object and do the same.

hellswraith: I wonder why I didn't think of that :-D thanks.
DevGrp: I would like to pass sTempFile and pTempProc to the KillFile() function in its own thread. is this possible?

Is this what you are trying to do??

private void KillFile(Process proc, string tempFile)
{
    proc.WaitForExit();
    File.Delete(tempFile);
}

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(pTempProc, sTempfile) ) );
        th.Start();
    }
    return;
}

I dont think that will work. You can't pass arguments to a method that is executed on a seperate thread other than the processess main thread. Though, I haven't tried the above example..

[sunburnt]

That's what I tried first. Apparently you can't do it like that.

Yep...Your best bet is to do what hellswraith suggested by wrapping your thread functionality into a seperate class.

You could use an async delegate, that way you can pass parameters to the function.
