第一步，用HttpClient访问http://login.live.com/login.srf?id=2，这个页面会返回一个登录表单

第二步，解析出form中所有的隐含变量和form的action，这些变量是你必须要通过httpClient Post回去,hotmail服务器会验证这些参数，另外，你还必须传递一个PwdPad变量，它的值是IfYouAreReadingThisYouHaveTooMuchFreeTime 从后面截取登录密码长度的值，比如你的密码是123,则PwdPad的值是IfYouAreReadingThisYouHaveTooMuchFreeT

第三、为了知道你接下来导向的地址，你必须解析服务器给你返回的脚本，其中relpace(”***”)中的***即为重定向的地址

第四、得到上一步重定向后的真实的主机地址，联系人列表页面的具体地址就是http://+ hostAddress + /mail/GetContacts.aspx

第五、用正则表达式解析此页面即可

具体代码如下:
