C# Active Directory的DifferentiedName属性

这是我的代码：

public bool ActiveDirectoryAuthenticate(string username, string password)
{
   var result = false;

   using (var entry = new DirectoryEntry("LDAP://*****/DC=******,DC=biz",username,password,AuthenticationTypes.Secure))
   {
       var searcher = new DirectorySearcher(entry){Filter = "objectClass=user"};

       try
       {
           var sr = searcher.FindOne();
           var PathDic = sr.Properties["distinguishedName"][0].ToString();
           result = true;
       }
       catch (Exception exception)
       {
       }
    }

    return result;
}

问题是

sr.Properties["distinguishedName"][0].ToString();

不返回正确的值

请帮我一个主意，但你不需要这样评价我吗

var PathDic = sr.Properties["distinguishedName"][0].Value.ToString();

我的问题解决：

public bool ActiveDirectoryAuthenticate(string username, string password)
    {
        var result = false;
        using (
            var entry = new DirectoryEntry("LDAP://PT/DC=pt,DC=biz", username, password,
                AuthenticationTypes.Secure))
        {
            var searcher = new DirectorySearcher(entry) {Filter = "sAMAccountName=Bank.Members"};

            searcher.PropertiesToLoad.Add("distinguishedName");
            try
            {
                var sr = searcher.FindOne();
                var name = sr.Properties["distinguishedName"][0].ToString();
                result = true;
            }
            catch (Exception exception)
            {


            }
        }

        return result;
    }

它的回报是什么？正确的值是多少？它只返回服务器名和域名，但我想返回我制作的目录。请给我们举个例子，并解释您期望/想要什么？我仍然不明白你的问题到底是什么……正确的：CN=BANK.Members，OU=MBank，OU=Development，OU=Technical，OU=pt，DC=pt，DC=biz不正确的：CN=Administrator，CN=Users，DC=pt，DC=biz
