c# 如何计算字符串的md5值

1、添加引用

using System.Security.Cryptography;

using System.Text;

2、编写如下代码

public static string GetMd5(string text)

 

        {

 

            StringBuilder sb = new StringBuilder();

 

            using (MD5CryptoServiceProvider md5 = new MD5CryptoServiceProvider())

 

            {

 

                byte[] data = md5.ComputeHash(Encoding.UTF8.GetBytes(text));

 

                int length = data.Length;

 

                for (int i = 0; i < length; i++)

 

                {

 

                    sb.Append(data[i].ToString("x2"));

 

                }

 

                return (sb.ToString());

 

            }

 

        }
