c#实现MD5加密

MD5加密，生成32为纯字符串，需要引用一下两个命名空间

using System.Security.Cryptography;



using System.Text;



 public string md5(string str)

 {



         MD5 m = new MD5CryptoServiceProvider();



         byte[] s =m.ComputeHash(UnicodeEncoding.UTF8.GetBytes(str));



         return BitConverter.ToString(s).Replace("-","");  //移除“-”



}
