问题描述

我如何使用带有vb.net的asp.net获取系统名称

我正在使用这个.
它在Lan上工作正常，但在WAN上却给了我客户端Ip而不是客户端系统名称

请帮助


暗淡的SystemName作为字符串= MachineName(Request.UserHostAddress)

How can i Get system name using asp.net with vb.net

I am using this .
Its working fine on Lan but on WAN it gives me client Ip Instead of Client system Name


Kindly Help


Dim SystemName As String = MachineName(Request.UserHostAddress)

Public Shared Function MachineName(ByVal clientIP As String) As String
     Try
         Dim hostEntry = System.Net.Dns.GetHostEntry(clientIP)
         Return hostEntry.HostName

     Catch ex As Exception

     End Try

推荐答案

尝试使用Request.ServerVariables["REMOTE_HOST"]

Try using Request.ServerVariables["REMOTE_HOST"]

<br />
System.Net.Dns.GetHostEntry

仅在可以访问域DNS服务器的局域网中工作.

will only work in a lan which has access to the domain DNS server.

它起作用

string sHostName = System.Net.Dns.GetHostName();
 System.Net.IPHostEntry ipE =System.Net.Dns.GetHostEntry(sHostName);
    System.Net.IPAddress[] IpA = ipE.AddressList; 

用于IP地址使用IpA [0] .ToString()
对于主机名，请使用sHostName
希望对您有帮助

for Ip address use IpA[0].ToString()
for Hostname use sHostName
hope it will helps
