.net中有没有办法获取用户的域名信息？

[chengpei_chen]

原来的一个项目做好后，用户要求用域名登陆，这样的话就会出现两次登陆。
当用户访问页面时首先要域名登陆，然后再登陆本系统。
能不能在.net中取得用户域名登陆信息，这样就不用再进入本系统的登陆界面，而是一域名身份直接登陆到本系统？

1. 在ASP.NET中专用属性：
获取服务器电脑名：Page.Server.ManchineName
获取用户信息：Page.User
获取客户端电脑名：Page.Request.UserHostName
获取客户端电脑IP：Page.Request.UserHostAddress

2. 在网络编程中的通用方法：
获取当前电脑名：static System.Net.Dns.GetHostName()
根据电脑名取出全部IP地址：static System.Net.Dns.Resolve(电脑名).AddressList
也可根据IP地址取出电脑名：static System.Net.Dns.Resolve(IP地址).HostName

3. 系统环境类的通用属性：
当前电脑名：static System.Environment.MachineName
当前电脑所属网域：static System.Environment.UserDomainName
当前电脑用户：static System.Environment.UserName

我现在只要在.net中得到用户在域登陆时的用户名就可以，其他的我也不需要。

看看这两个方法

public class Win32API
{
[DllImport("netapi32.dll",EntryPoint="NetApiBufferFree")]
internal static extern void NetApiBufferFree(IntPtr bufptr);

\\用来取得特定组所有用户的信息
[DllImport("netapi32.dll",EntryPoint="NetLocalGroupGetMembers")]
internal static extern uint NetLocalGroupGetMembers(
IntPtr serverName,
IntPtr GroupName,
uint level,
ref IntPtr siptr,
uint prefmaxLen,
ref uint entriesRead,
ref uint totalentries,
IntPtr resumeHandle);

\\用来取得所有组的信息
[DllImport("netapi32.dll",EntryPoint="NetLocalGroupEnum")]
internal static extern uint NetLocalGroupEnum(
IntPtr serverName,uint level,ref IntPtr siptr,uint prefmaxLen,ref uint entriesRead,ref uint totalLentries,IntPtr resumeHandle);

用
string s=System.Environment.UserDomainName;
就可以得到登陆用户名
