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());
            }
        }
