如何获取客户端计算机主机名。 [英] How to get client machine host name.

问题描述

大家好，



我在Windows 7 64位机器上使用过VS2010。我可以在32位机器上获得主机名并且工作正常。但是当我使用64位机器时，我得到了没有这样的主机已知的错误。

我尝试了所有这3个ServerVariables但仍然有错误。

Hello all,

I have used VS2010 on windows 7 64bit machine. I can get host name on 32bit machine and working fine. But I got error as "No such Host is known" when using 64bit machine.
I was tryed all these 3 ServerVariables but still i got error.

Request.ServerVariables["REMOTE_ADDR"]
Request.ServerVariables["REMOTE_HOST"]
Request.ServerVariables["REMOTE_USER"]

我的代码是：

My code is:

string hName = "";
System.Net.IPHostEntry host = new System.Net.IPHostEntry();
host = System.Net.Dns.GetHostEntry(HttpContext.Current.Request.ServerVariables["REMOTE_HOST"]);

if (host.HostName.Contains("."))
{
string[] sSplit = host.HostName.Split('.');
hName = sSplit[0].ToString();
}
else
{
hName = host.HostName.ToString();
}

推荐答案

它与机器的位数无关。它与远程机器是否在服务器可访问的DNS中注册有关。显然，您的64位计算机不是。

It has nothing to do with the bitness of the machine. It has everything to do with whether the remote machine is registered in a DNS accessible by the server or not. Apparently, your 64-bit machine is not.

Shrotest Way to get Client PCName

string clientPCName;
string[] computer_name = System.Net.Dns.GetHostEntry(
Request.ServerVariables["remote_host"]).HostName.Split(new Char[] { '.' });
clientPCName = computer_name[0].ToString();
