我是asp.net新手,我有新任务要从Active Directory检索所有用户。当我试图从Active Directory检索所有用户时,我只得到一个用户

private void btngetuser_Click(object sender, EventArgs e)
{
        DirectorySearcher searcher = new DirectorySearcher();
        searcher.SearchScope = SearchScope.Subtree;
        searcher.Filter = string.Format(CultureInfo.InvariantCulture, "(sAMAccountName={0})", Environment.UserName);
        //SearchResult findUser = searcher.FindOne();

        foreach (SearchResult findUser in searcher.FindAll())
        {
            if (findUser != null)
            {
                DirectoryEntry user = findUser.GetDirectoryEntry();
                string userName = user.Properties["displayName"].Value.ToString();
                string Email = user.Properties["mail"].Value.ToString();
                string Mobile = user.Properties["Mobile"].Value.ToString();
                string Login = user.Properties["sAMAccountName"].Value.ToString();
                string[] rt = new string[] { Login, userName, Email, Mobile };
                dataGridView1.Rows.Add(rt);
            }
        }
    }

你用的是过滤器,对吗?为什么您希望此按登录名筛选的查询将返回AD中的所有用户,而不是您要求的用户?

您可以使用
原则搜索器和“示例查询”原则进行搜索:

// create your domain context
using (PrincipalContext ctx = new PrincipalContext(ContextType.Domain))
{
   // define a "query-by-example" principal - here, we search for  UserPrincipal (users)
   UserPrincipal qbeUser = new UserPrincipal(ctx);

   // create your principal searcher passing in the QBE principal    
   PrincipalSearcher srch = new PrincipalSearcher(qbeUser);

   // find all matches
   foreach(var found in srch.FindAll())
   {
       // do whatever here - "found" is of type "Principal" - it could be user, group, computer.....          
       UserPrincipal foundUser = found as UserPrincipal;

       if(foundUser != null)
       { 
            string userName = foundUser.DisplayName;
            string email = foundUser.Email;
            string login = foundUser.SamAccountName;
        }
   }
}

如果您还没有-请阅读MSDN文章,这篇文章很好地展示了如何最好地利用
System.DirectoryServices.AccountManagement
中的新功能。或者查看名称空间。

您可能只有一个用户,因为
SamAccountName
在用户中必须是唯一的-因此,如果您搜索一个特定的
SamAccountName
,您将永远不会得到超过一个的点击率…是的,您已经指定要获取一个特定用户的信息,即当前登录的用户。如果你想获得广告中的所有用户,你必须使用另一个过滤器。在这个中间的某个地方有这个任务的描述。有没有办法用姓氏或名字或其他标准来排序结果?
