局域网得到所有计算机名称的问题，我看了以前的贴子，自己没有成功。一定给分

[Sean_JIN]

能不能给出具体的代码或有代码的连接。
System.Net.IPAddress[] addressList =
Dns.GetHostByName(Dns.GetHostName()).AddressList;
中的
addressList[i].ToString()只是本机的地址。

都是得到本机的IP，这个早知道了。
我要得到当前局域网的所有计算机的名称和IP，用遍隶地址的方法也是不可取的，因为时间太长。

有个方法：
可以通过循环IP来得到计算机名
System.Net.Dns.GetHostByAddress(“IP地址”).HostName

你有网域管理员权限吗?

ADSI,方法与TheArea说的一样。

绝对能成功，不要怀疑，就看你写的程序对不对，不管你是不是域管理员，只要你在这个域内。

[TheAres]

用ADSI实现,

可以将路径指定为 "WinNT: "枚举出一个局域网内所有的域，如下列代码所示：

DirectoryEntry objSpace = new DirectoryEntry( "WinNT: ");
foreach(DirectoryEntry domain in objSpace.Children)
System.Diagnostics.Debug.WriteLine(domain.Name);

如果要枚举一个组中的所有成员，首先要激活其Members成员，并查询（映射到）他的IEnumerable接口。然后遍历其中每一个元素，生成相应的入口对象并输出。如下列代码所示：

string domainName = "Domain ";
string groupName = "Group ";
DirectoryEntry group = new DirectoryEntry( "WinNT:// " + domainName + "/ " + groupName + ",group ");

foreach(Object member in (IEnumerable)group.Invoke( "Members "))
{
DirectoryEntry dirmem = new DirectoryEntry(member);
Console.WriteLine(dirmem.Name);
}
