C # automatically submit to Baidu ping Service

I have no intention of seeing this ping service in Baidu webmaster today )....

So what is Ping service?

Ping is an update Notification Service Based on the XML_RPC standard protocol. It is used by a blog to quickly notify Baidu of content updates, so that Baidu can capture and update content in a timely manner.

It looks like a simple http post submission. However, when you use WebRequest to simulate the request, the return operation times out. It's speechless.

The following is an example of the Baidu ping Service (note that the red part. Now the http Version is 1.1. This is the details that make it unable to be submitted). By the way, the Fiddler tool is really useful.
