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());}}
