Recently made a simulated in c # the browser receives the HTTPS web data tools, encounter problems card for several days, a great god give advice or comments, please, be obliged, all scores to send,
Caught tool fiddler fetching browser to access the HTTPS site data, will first have a HTTP handshake bag (presumably verification certificate, key, etc.), and then the HTTPS packets,
As shown in gray line:

The browser sends the handshake packet head looks something like this:
The CONNECT HTTP/1.1
www.hao123.com:443Host: www.hao123.com:443
Connection: keep alive -
The user-agent: Mozilla/5.0 (Windows NT 6.1; Win64. X64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36
A SSLv3 - compatible ClientHello handshake was found. Fiddler extracted the parameters below.

C # use HttpWebRequest send package, there is no the user-agent to shake hands with this one, looked through the data, probably understood as the action of shaking hands is the underlying SSL encapsulation, the. Net framework and no interface to write it?
Note that I mean the connect to begin with, the HTTP protocol handshake this package, not shake hands after a successful get the HTTPS protocol, post the package,
Please the great god your advice, I thank you, here be obliged,
If this is the innate defect of c #, please to provide a direction to solve the problem, thank you...
