既然你在.NET 3.5及以上，你应检查System.DirectoryServices.AccountManagement（S.DS.AM）命名空间。在这里阅读全部内容：

Managing Directory Security Principals in the .NET Framework 3.5

基本上，你可以定义域范围内，并可以轻松地查找用户和/或组AD：

public string GetLoginName(string userName) 
{ 
    // set up domain context 
    PrincipalContext ctx = new PrincipalContext(ContextType.Domain); 

    // find user by name 
    UserPrincipal user = UserPrincipal.FindByIdentity(ctx, userName); 

    if(user != null) 
     return user.SamAccountName; 
    else 
     return string.Empty; 
} 

新S.DS.AM使它真的很容易在公元玩弄用户和组：

使用.NET库中，可以使用下面的代码来获取用户名得到他的登录名后或从Active Directory

using System.Management; 
using System.Management.Instrumentation; 
using System.Runtime.InteropServices; 
using System.DirectoryServices; 

ManagementObjectSearcher Usersearcher = new ManagementObjectSearcher("Select * From Win32_ComputerSystem Where (Name LIKE 'ws%' or Name LIKE 'it%')"); 
      ManagementObjectCollection Usercollection = Usersearcher.Get(); 
      string[] sep = { "\\" }; 
      string[] UserNameDomain = Usercollection.Cast<ManagementBaseObject>().First()["UserName"].ToString().Split(sep, StringSplitOptions.None); 

我添加任何信息 “SELECT * FROM的Win32_ComputerSystem哪里（名称，如 'WS％' 或名称LIKE '它％'）” 这将由全名获取用户名

不认同：

private string GetLogonFromDisplayName(string displayName) 
{ 
    var search = new DirectorySearcher(string.Format("(&(displayname={0})(objectCategory=user))", displayName)); 
    search.PropertiesToLoad.Add("sAMAccountName"); 

    SearchResult result = search.FindOne(); 
    if (result != null) 
    { 
     var logonNameResults = result.Properties["sAMAccountName"]; 
     if (logonNameResults == null || logonNameResults.Count == 0) 
     { 
      return null; 
     } 

     return logonNameResults[0].ToString(); 
    } 

    return null; 
}
