需要使用C#的当前组织中的所有用户详细信息(姓名、电子邮件、指定名称、部门)

Question

我跟踪了C# LDAP query to retrieve all users in an organisational unit和"A referral was returned from the server" exception when accessing AD from C#的链接

我需要知道我在LDAP路径上做错了什么?

 // create your domain context and define what container to search in - here OU=Employees
        PrincipalContext ctx = new PrincipalContext(ContextType.Domain, "MS", "OU=Employees,DC=CompanyName,DC=com");

        // define a "query-by-example" principal - here, we search for a UserPrincipal 
        // that is still active
        UserPrincipal qbeUser = new UserPrincipal(ctx);
        qbeUser.Enabled = true;

        // 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.....          
        }

我需要所有用户的详细信息(姓名，电子邮件，指定，部门)在目前的组织使用C#和显示在下拉列表。请帮帮忙。

public DataTable FindPersons(string lname, string fname)
    { 

        DirectorySearcher searcher = new DirectorySearcher();
        searcher.Filter = string.Format("(&(objectCategory=person)(objectClass=user)(givenname={0}*)(sn={1}*))", fname, lname);

        SearchResultCollection allResults;
        allResults = searcher.FindAll();

        DataTable dt = new DataTable();
        dt.Columns.Add("DisplayName", typeof(string));
        dt.Columns.Add("GivenName", typeof(string));
        dt.Columns.Add("SurName", typeof(string));
        dt.Columns.Add("MSID", typeof(string));
        if (allResults.Count >= 0)
        { 
            for (int i = 0; i < allResults.Count; i++)
            {
                DirectoryEntry deMembershipUser = allResults[i].GetDirectoryEntry();
                deMembershipUser.RefreshCache(); 

                dt.Rows.Add(
                    (string)deMembershipUser.Properties["displayname"].Value, 
                    (string)deMembershipUser.Properties["givenName"].Value,
                    (string)deMembershipUser.Properties["sn"].Value, 
                    (string)deMembershipUser.Properties["cn"].Value
                    ); 
            } 
        } 
        return dt;
    }
