字符串MD5加密和产生一个随机密码的方法

  //MD5加密
  public static string ToMD5Hash(string inputString)

   Byte[] ByteToHash = sysEncode.GetBytes(inputString);
   Byte[] HashValue =  ((System.Security.Cryptography.HashAlgorithm) System.Security.Cryptography.CryptoConfig.CreateFromName    ("MD5")).ComputeHash(ByteToHash);
   return System.BitConverter.ToString(HashValue); 
  }

    //产生随机密码
  public static string GetRadomPassword(int Length)
  {
   System.Text.StringBuilder Password = new System.Text.StringBuilder();
   Random RandomMach = new Random(DateTime.Now.Millisecond);

   //得到一个Length位的随机密码
   for(int i=0; i<Length; i++)
   {
    int RandomChar = RandomMach.Next(25)+97;   //ASCII(a)=97,得到一个小写字母串作为密码
    Password.Append((char)RandomChar);
   }
   return Password.ToString();
  }
