In. NET, the WebService and WebForm pages use different methods of obtaining client IP.

Note: The following methods are in. NET2.0 on the test pass.

Web Service uses (invokes the request object via the HttpContext object):

HttpContext.Current.Request.UserHostAddress

HttpContext.Current.Request.ServerVariables.GetValues ("remote_addr") [0]

Web form uses (you can use the request object directly):

Request.ServerVariables.GetValues ("remote_addr") [0]

HttpContext.Current.Request.UserHostAddress

----

Answer 1:
ServerVariables Data collection:
Request.ServerVariables ("Environment variable name")
LOCAL_ADDR returns the server-side computer IP address
SERVER_NAME returns the computer name, DNS alias, or IP address of the Web server side
REMOTE_ADDR Remote Host IP address
Remote_host the remote host name
