如何获得在C＃中的DHCP信息？ [英] How to get DHCP information in C#?

问题描述

我想获得DHCP选项在C＃15的信息。我不想通过dhcpsapi.dll虽然打电话，因为我不想被限于的Windows的DHCP服务器做。有一些其他的方式，通过C＃来获取DHCP信息，还是我将不得不handcode呢？

I would like to get DHCP Option 15 information in C#. I do not want to call through dhcpsapi.dll though, because I don't want to be limited to just Windows DHCP servers. Is there some other way to get DHCP information through C# or am I going to have to handcode this?

推荐答案

您可以使用WMI和Win32_NetworkAdapterConfiguration类。
一个可用字段返回的DNSHOSTNAME这似乎是DHCP选项15。

You can use WMI and the Win32_NetworkAdapterConfiguration class. One of the available fields returned is DNSHostName which seems to be DHCP option 15.

ManagementObjectSearcher query = new ManagementObjectSearcher("SELECT * FROM Win32_NetworkAdapterConfiguration WHERE IPEnabled = 'TRUE'") ;
ManagementObjectCollection queryCollection = query.Get();
foreach( ManagementObject mo in queryCollection )
{
    string dnsName = (string[])mo["DNSHostName"];
    Console.WriteLine("IP Address: {0}", ipaddress);
}
