在.NET中，WebService和WebForm頁面
 
Web Service使用(通過HttpContext對象調用Request對象)：
HttpContext.Current.Request.UserHostAddress
HttpContext.Current.Request.ServerVariables.GetValues("REMOTE_ADDR")[0]
Web Form使用（可直接使用Request對象）：
Request.ServerVariables.GetValues("REMOTE_ADDR")[0]
HttpContext.Current.Request.UserHostAddress
