C # display a new form in the thread

In multiple threads, some results must be displayed at the end of a thread. I use a new form to display the results. But simply write the following in the thread body:

 

  1 private void ThreadFunc()
 2 {
 3      MsgForm msg = new MsgForm();
 4      msg.Show();
 5 }
 6 private void button1_Click(object sender, System.EventArgs e)
 7 {
 8      FormThread = new Thread(new ThreadStart(ThreadFunc));
 9      FormThread.Start();
10 }

 

 

The generated form is lost in a flash. This is because all the resources in the form created in the thread belong to this thread, so when this thread ends, its resources are also recycled, of course, C # automatically closes the form.

The correct method is to use Invoke. The Code is as follows:

 

  1 private void ThreadFunc()
 2 {
 3      MethodInvoker mi = new MethodInvoker(this.ShowMsgForm);
 4      this.BeginInvoke(mi);
 5 }
 6 private void ShowMsgForm()
 7 {
 8      MsgForm msg = new MsgForm();
 9      msg.Show();
10 }
11 private void button1_Click(object sender, System.EventArgs e)
12 {
13      FormThread = new Thread(new ThreadStart(ThreadFunc));
14      FormThread.Start();
15 }
