In C# how do I get the list of local computer names like what one gets viewing the Network in windows explorer
提问by Alex McBride
There are a lot of questions about getting the name and IP addresses of the local machine and several about getting IP addresses of other machines on the LAN (not all answered correctly). This is different.
有很多关于获取本地机器的名称和IP地址的问题以及一些关于获取LAN上其他机器的IP地址的问题（并非所有答案都正确）。这是不同的。
In windows explorer if I select Network on the side bar I get a view of local machines on my LAN listed by machine name (in a windows workgroup, anyway). How do I get that same information programatically in C#?
在 Windows 资源管理器中，如果我在侧栏上选择网络，我会看到 LAN 上按机器名称列出的本地机器（无论如何在 Windows 工作组中）。如何在 C# 中以编程方式获取相同的信息？

You can try using the System.DirectoryServicesnamespace.
您可以尝试使用System.DirectoryServices命名空间。
var root = new DirectoryEntry("WinNT:");
foreach (var dom in root.Children) {
foreach (var entry in dom.Children) {
if (entry.Name != "Schema") {
Console.WriteLine(entry.Name);
}
}
}

You need to broadcast an ARP request for all IPs within a given range. Start by defining the base IP on your network and then setting an upper identifier.
您需要为给定范围内的所有 IP 广播 ARP 请求。首先定义网络上的基本 IP，然后设置上层标识符。
I was going to write up some code examples etc but it looks like someone has covered this comprehensively here;
我打算写一些代码示例等，但看起来有人在这里全面介绍了这一点；

public List<String> ListNetworkComputers()
{
List<String> _ComputerNames = new List<String>();
String _ComputerSchema = "Computer";
System.DirectoryServices.DirectoryEntry _WinNTDirectoryEntries = new System.DirectoryServices.DirectoryEntry("WinNT:");
foreach (System.DirectoryServices.DirectoryEntry _AvailDomains in _WinNTDirectoryEntries.Children)
{
foreach (System.DirectoryServices.DirectoryEntry _PCNameEntry in _AvailDomains.Children)
{
if (_PCNameEntry.SchemaClassName.ToLower().Contains(_ComputerSchema.ToLower()))
{
_ComputerNames.Add(_PCNameEntry.Name);
}
}
}
return _ComputerNames;
}
