Determine Client's Computer Name
提问by Jimmy
I am building an intranet site that will display different lists based on the computer name because different computers are in different areas, is there a way (within a controller or model) to determine the client's computer name?
我正在构建一个 Intranet 站点，它将根据计算机名称显示不同的列表，因为不同的计算机位于不同的区域，有没有办法（在控制器或模型内）确定客户端的计算机名称？
I have tried system.environment.machinename but that only returns the name of the server, any other ideas?
我试过 system.environment.machinename 但它只返回服务器的名称，还有其他想法吗？

I got it working using the following:
我使用以下方法让它工作：
string IP = Request.UserHostName;
string compName = CompNameHelper.DetermineCompName(IP);
code from compnamehelper:
来自 compnamehelper 的代码：
public static string DetermineCompName(string IP)
{
IPAddress myIP = IPAddress.Parse(IP);
IPHostEntry GetIPHost = Dns.GetHostEntry(myIP);
List<string> compName = GetIPHost.HostName.ToString().Split('.').ToList();
return compName.First();
}

The only way I know of to inspect the client is through the ServerVariables collection on the Request object (should be available for MVC code).
我所知道的检查客户端的唯一方法是通过 Request 对象上的 ServerVariables 集合（应该可用于 MVC 代码）。
See http://www.4guysfromrolla.com/webtech/092298-3.shtmlfor more information. REMOTE_HOST and REMOTE_ADDR look like candidates.
有关更多信息，请参阅http://www.4guysfromrolla.com/webtech/092298-3.shtml。REMOTE_HOST 和 REMOTE_ADDR 看起来像候选对象。

I think you are better off using one of these methods to tie a user to a location:
我认为您最好使用以下方法之一将用户绑定到某个位置：
- a cookie that is set once the user self-selects their location
- having the user login to the site so that you can track them uniquely that way
- remembering user by IP address
- 用户自行选择位置后设置的 cookie
- 让用户登录到该站点，以便您可以通过这种方式唯一地跟踪他们
- 通过 IP 地址记住用户
There is no way of ensuring remote hostnames are unique. The same issue occurs with IP because of proxies, dynamic IP, etc., but I think it will be a little more reliable. Also, you can do geolocation by IP address.
无法确保远程主机名是唯一的。由于代理，动态IP等，IP也会出现同样的问题，但我认为它会更可靠一些。此外，您可以通过 IP 地址进行地理定位。

No. The client's computer name is not available in any way on the server. This is the nature of the http request-response. You only can have its IP address.
否。客户端的计算机名称在服务器上以任何方式都不可用。这就是 http 请求-响应的本质。您只能拥有其 IP 地址。
A workarounds could be to retrieve machine on the client from Flash/Silverlight (I doubt JavaScript) and put in into cookie which is available on the server with each request. But there is a whole stack of issues with this approach.
一种解决方法可能是从 Flash/Silverlight（我怀疑 JavaScript）检索客户端上的机器，并将其放入服务器上随每个请求提供的 cookie 中。但是这种方法有很多问题。

Here's an IE-only solution. It works in IE8, with multiple security warnings.
这是一个仅限 IE 的解决方案。它适用于 IE8，带有多个安全警告。
<script type="text/javascript" language="javascript">
var ax = new ActiveXObject("WScript.Network");
document.write(ax.UserName + '<br />'); //logged in account name
document.write(ax.ComputerName + '<br />'); //Windows PC name
</script>

code in VB :
VB中的代码：
Dim myIP As IPAddress = IPAddress.Parse(Request.UserHostName)
Dim GetIPHost As IPHostEntry = Dns.GetHostEntry(myIP)
Dim compName As List(Of String) = GetIPHost.HostName.ToString.Split("").ToList
return(compName.First)
