一、计算文件MD5值的方法:
/// <summary>/// 计算文件MD5值/// </summary>/// <param name="str">需要计算的文件路径</param>/// <returns>MD5值</returns>public static string MD5Value(String filepath){MD5 md5 = new MD5CryptoServiceProvider();byte[] md5ch;using (FileStream fs = File.OpenRead(filepath)){md5ch = md5.ComputeHash(fs);} md5.Clear();string strMd5 = "";for (int i = 0; i < md5ch.Length - 1; i++){strMd5 += md5ch[i].ToString("x").PadLeft(2, '0');}return strMd5;}
二、计算文件MD5值的方法:
//计算字符串MD5值的方法:public static string GetMD5(string sDataIn){MD5CryptoServiceProvider md5 = new MD5CryptoServiceProvider();byte[] bytValue, bytHash;bytValue = System.Text.Encoding.UTF8.GetBytes(sDataIn);bytHash = md5.ComputeHash(bytValue);md5.Clear();string sTemp = "";for (int i = 0; i < bytHash.Length; i++){sTemp += bytHash[i].ToString("X").PadLeft(2, '0');}return sTemp.ToLower();}
