所以，我想创建一个工具来注册一个新的 Live ID 并检查是否存在 Id vailable [Winform- C# - HttpWebRequest] 我使用 fiddler 来捕获 GET/POST 请求，但我没有看到参数发布到服务器（用户名=xxx&密码= xxx&xxx)。注册链接：Live.com 我该怎么办？
Winform： - 文本框：用户名、密码、电子邮件地址 - 显示验证码表单 signup.live.com 供用户填写 - 按钮：注册。当我单击按钮时，它将在 signup.live.com 上自动注册（获取参数用户填写）。
================= 编辑：提琴手嗅探：
