Question

I am running a thread like this:

instance variable

private Thread workerThread = null;

in contructor

workerThread = new Thread(new ThreadStart(this.remoteRequestBackgroundTask));

in a method, I start the thread

    private void btnTransferData_Click(object sender, EventArgs e)
    {
        ////Start the thread
        workerThread.Start();
        //remoteRequestBackgroundTask();
    }

remoteRequestBackgroundTask

    private void remoteRequestBackgroundTask()
    {
      //does some background processing and then finishes
     }

This works the first time I run the Thread, however, when it finishes and I run it again, I get “System.Threading.ThreadStateException”. How can I fix this?

Do not create the worker thread in the constructor. You should move this code into the btnTransferData_Click method.
