Hello Experts,

How do I enhance my code check if a thread is running, if YES it create a new thread in addition to the running one

Thanks

Thread myThread = new System.Threading.Thread(delegate()
{
//Your code here
System.Threading.Thread.Sleep(14000);
close_window_by_handle(ie);
});
myThread.Start();

How do I enhance my code check if a thread is running, if YES it create a new thread in addition to the running one

What do you mean by "else it use the Stopped thread?" A terminated thread cannot be restarted, and you must create a new Thread instance in that case.

Is this a desktop app (eg. Winform) or Asp.net?
How many threads are you running in parallel in your App?
If this number is small (<20) then you can use ThreadPool.QueueUserWorkIt
else consider using TPL (.Net 4.0 up)
Note: Check TPL vs queueuserworkitem

I looked again to the request, I think that TPL can be helpful for me
can you please help to convert my code to TPL

using System.Threading.Tasks;
Your code should look like:
Parallel.Invoke(
() => {
//Your code here
System.Threading.Thread.Sleep(14000);
close_window_by_handle(ie);
}
);
If you are returning a value use:
Task<int> task1 = Task<int>.Factory.StartNew(() => DoWork());
// Get the results and write them out.
Console.WriteLine("Result ={0}", task1.Result);
where
static int DoWork()
{
//Your code here
System.Threading.Thread.Sleep(14000);
close_window_by_handle(ie);
return 0;
}
