[Practice] + use C # to implement multi-threaded file transmission over HTTP

Today, I saw an example about "multithreading", and I felt pretty good, so I started my work.

Because I didn't see any images before, I just practiced it step by step based on the text introduction. It is a little different. If you are interested, you can do it yourself.

My development environment is Microsoft Visual Studio 2005, which is different from the development environment of the author (visual studio.net 2002 development environment and Windows XP operating system:

Solution:
// Form1.cs
Delegate void setlistboxcallback (string ListBox );
......
Public void setlistbox (string ListBox)
{
// Invokerequired required compares the thread ID of
// Calling thread to the thread ID of the creating thread.
// If these threads are different, it returns true.
If (this. listbox1.invokerequired)
{
Setlistboxcallback d = new setlistboxcallback (setlistbox );
This. Invoke (D, new object [] {ListBox });
}
Else
{
This. listbox1.items. Add (ListBox );
}
}

// Httpfile. CS
// Formm. listbox1.items. Add ("Thread" + threadh. tostring () + "start receiving ");
Formm. setlistbox ("Thread" + threadh. tostring () + "start receiving ");

1. I recently read some basic knowledge about multithreading. I think this example is classic and interesting. I would like to share it with you;
2. If you have any suggestions or comments on learning "multithreading" or related materials, thank you for your consideration.
