C# 实现计算MD5 32位大小写，16位大小写算法的函数实例

C# 实现计算MD5 32位大小写，16位大小写算法实例

1、引入命名空间

using System;

using System.Text;

using System.Windows.Forms;

using System.Security.Cryptography;

2、函数如下

        public static string GetMd5Str_16D(string ConvertString) //16位大写
        {
            MD5CryptoServiceProvider md5 = new MD5CryptoServiceProvider();
            string t2 = BitConverter.ToString(md5.ComputeHash(UTF8Encoding.Default.GetBytes(ConvertString)), 4, 8);
            t2 = t2.Replace("-", "");
            return t2;
        }
        public static string GetMd5Str_16X(string ConvertString) //16位小写
        {
            MD5CryptoServiceProvider md5 = new MD5CryptoServiceProvider();
            string t2 = BitConverter.ToString(md5.ComputeHash(UTF8Encoding.Default.GetBytes(ConvertString)), 4, 8);
            t2 = t2.Replace("-", "");


            t2 = t2.ToLower();


            return t2;
        }
        public string GetStrMd5_32D(string ConvertString) //32位大写
        {




            MD5CryptoServiceProvider md5 = new MD5CryptoServiceProvider();
            string t2 = BitConverter.ToString(md5.ComputeHash(UTF8Encoding.Default.GetBytes(ConvertString)));
            t2 = t2.Replace("-", "");
            return t2;
        }
        public string GetStrMd5_32X(string ConvertString) //32位小写
        {




            MD5CryptoServiceProvider md5 = new MD5CryptoServiceProvider();
            string t2 = BitConverter.ToString(md5.ComputeHash(UTF8Encoding.Default.GetBytes(ConvertString)));
            t2 = t2.Replace("-", "");
            return t2.ToLower();

        }
