asp.net MD5加密函數(c#)

標籤：

利用下面的方法，可直接輸入資料，反回md5加密後的代碼

/// <summary> /// 用md5加密 /// </summary> /// <param name="Sourcein">輸入的資料</param> /// <returns></returns> public static string MD5(string Sourcein) {    MD5CryptoServiceProvider MD5CSP = new MD5CryptoServiceProvider();    byte[] MD5Source = System.Text.Encoding.UTF8.GetBytes(Sourcein);    byte[] MD5Out = MD5CSP.ComputeHash(MD5Source);    return Convert.ToBase64String(MD5Out); }

以上只是適用於.net的MD5加密，但是現在很多公司處於asp轉asp.net的階段，為了不改動原來的教大的使用者資料庫，我們需要找到一種跟asp的md5加密後相同的結果，下面的代碼是我曾經用過的，給出來大家參考：黃色部分代碼
