md5加密

先引用兩個命名空間

using System.Security.Cryptography;using System.Text;

以下是md5加密方法

/// <summary>        /// md5加密--32位        /// </summary>        /// <param name="text"></param>        /// <returns></returns>        public static string md5jiami(string text)        {            byte[] result = Encoding.Default.GetBytes(text);            MD5 md5 = new MD5CryptoServicePRovider();            byte[] output = md5.ComputeHash(result);            string s = BitConverter.ToString(output).Replace("-", "");            return s;        }
