問題描述

好的.所以我試圖找到一種方法來避免在我的項目中包含 ActiveD，因為我無法讓 dll 顯示在安裝程序中.擁有它的唯一原因是將 pwdLastSet 轉換為 LongInteger.

Ok. So I'm trying to find a way to avoid including ActiveDs in my project because I'm having trouble getting the dll to show up in the installer. The only reason to have it is to cast the pwdLastSet as a LongInteger.

我找到了一個無證替代品.測試它時，它要么完全開啟，要么關閉 429.49673 秒.我不知道為什么，有人知道嗎?(我測試的 20/49 人的時間為 429.49673 秒).

I found an undocumented alternative. When testing it, it is either dead on or 429.49673 seconds off. I'm not sure why, does anybody have any idea? (20/49 people that i tested are 429.49673 seconds off).

UPDATE:看起來像是 LowPart 為負時發生的.

UPDATE: It looks like it happens when the LowPart is negative.

代碼:

    private static string DateTest() {
        return DateTest(Environment.UserName);
    }
    private static string DateTest(string userName) {
        userName = userName.Trim();
        DateTime hacked, normal;
        using (DirectorySearcher ds = new DirectorySearcher()) {
            ds.SearchScope = SearchScope.Subtree;
            ds.PropertiesToLoad.Add("distinguishedName");
            ds.PropertiesToLoad.Add("pwdLastSet");
            ds.PageSize = 1;
            ds.ServerPageTimeLimit = TimeSpan.FromSeconds(2);
            ds.Filter = string.Format("(&(objectCategory=user)(sAMAccountName={0}))", userName);

            SearchResult sr = ds.FindOne();
            hacked = DateTime.FromFileTime((long)sr.Properties["pwdLastSet"][0]);

            using (DirectoryEntry user = sr.GetDirectoryEntry()) {
                var value = user.Properties["pwdLastSet"][0] as ActiveDs.LargeInteger;
                var longValue = (((long)value.HighPart) << 32) + (long)value.LowPart;
                normal = DateTime.FromFileTime(longValue);
            }
        }

        return string.Format("{3} - Difference: {0:0.0} seconds. Established Method returns: {1}. Hacked method returns: {2}",
            hacked.Subtract(normal).TotalSeconds, normal, hacked, userName);
    }
}

推薦答案

你需要像這樣翻譯 AD Long Integer 并且你不再需要 ActiveDs:

You'll need to translate the AD Long Integer like this and you shouldn't need ActiveDs anymore:

long pwdLastSet = CovertADSLargeIntegerToInt64(oUser.Properties["pwdLastSet"].Value);

public static Int64 ConvertADSLargeIntegerToInt64(object adsLargeInteger)
{
  var highPart = (Int32)adsLargeInteger.GetType().InvokeMember("HighPart", System.Reflection.BindingFlags.GetProperty, null, adsLargeInteger, null);
  var lowPart  = (Int32)adsLargeInteger.GetType().InvokeMember("LowPart",  System.Reflection.BindingFlags.GetProperty, null, adsLargeInteger, null);
  return highPart * ((Int64)UInt32.MaxValue + 1) + lowPart;
}
