使用线程时UI无响应

Question

I was using Thread to start two functions AllCase and run them in parallel.

Thread t1, t2;
t1 = new Thread(new ThreadStart(AllCase))
{
    Name = "Thread1"
};
t1.Start();

t2 = new Thread(new ThreadStart(AllCase))
{
    Name = "Thread2"
};
t2.Start();
t1.Join();
t2.Join();

When Thread starts, I can't interact with the UI of application.

I read using BackgroundWorker .

But I want to get Name = "Thread1" to use, like this:

int idx = int.Parse(Thread.CurrentThread.Name.Replace("Thread", "")) - 1;

The values idx to know this process[idx] to easy manipulate.

And BackgroundWorker is not working correctly in my case.

So, have any method to resolve my problem?

Answer 1

remove these two lines:

t1.Join();
t2.Join();

and your GUI should become responsive again. Unless of course you have to wait for the methods to be completed in this order, but then you don't really need to use threads.
