C # HttpWebRequest continuous post

Hreq. Timeout = 2000;
The main reason for adding the above Code is that the default request timeout time is 100 seconds. when too many requests are opened and the main thread is blocked, what you said will happen.

I put my code in The onclick event of a Button. It can be normally displayed as 10. No problem. Didn't you leave the code in the Form constructor?

C # winform uses httpwebrequest and httpwebresponse for response. The response speed is sometimes slow. I don't know why

Httpwebrequest ----> http protocol
