MD5散列在C＃和PHP中不匹配

I have tried hashing a string in PHP using MD5 and the same in C#, but the results are different.. can someone explain me how to get this matched?

我已经尝试使用MD5在PHP中散列字符串和在C＃中使用相同的字符串，但结果是不同的...有人可以解释我如何使其匹配吗？

my C# code looks like

我的C＃代码看起来像

md5 = new MD5CryptoServiceProvider();
            originalBytes = ASCIIEncoding.Default.GetBytes(AuthCode);
            encodedBytes = md5.ComputeHash(originalBytes);

            Guid r = new Guid(encodedBytes);
            string hashString = r.ToString("N");

Thanks in advance

提前致谢

Edited: My string is 123 as a string

Your problem is here:

你的问题在这里：

Guid r = new Guid(encodedBytes);
string hashString = r.ToString("N");

I'm not sure why you're loading your encoded bytes into a Guid, but that is not the correct way to convert bytes back to a string. Use BitConverter instead:

我不确定你为什么要将编码的字节加载到Guid中，但这不是将字节转换回字符串的正确方法。改为使用BitConverter：

string testString = "123";
byte[] asciiBytes = ASCIIEncoding.ASCII.GetBytes(testString);
byte[] hashedBytes = MD5CryptoServiceProvider.Create().ComputeHash(asciiBytes);
string hashedString = BitConverter.ToString(hashedBytes).Replace("-", "").ToLower();
// hashString == 202cb962ac59075b964b07152d234b70
