在C＃和Python中生成base64编码的md5

Question

我正在尝试将python代码转换为C＃语言，而转换我已经部分实现了我的目标，只使用一个简单的字符串，例如两种语言中的“abc”并生成相同的编码字符串，但我在这里遇到了json对象python代码。

的Python

import base64 , hashlib , hmac , json , httplib , socket , re , email,ssl,os
from time import strptime , mktime , timezone , time , gmtime , strftime , daylight



h=hashlib.new ('md5')
h.update(json.dumps({"username":"sym","password":"123"}))
pprint.pprint(h.digest())

pprint.pprint(base64 . b64encode(h.digest()))

C＃

    static string GetMd5Hash(MD5 md5Hash, string input)
        {

        Credentials cred = new Credentials();
                cred.username = "sym";
                cred.password = "123";
                string output = JsonConvert.SerializeObject(cred);
byte[] data = md5Hash.ComputeHash(Encoding.UTF8.GetBytes(output));
 string s  = Convert.ToBase64String(data);
return s ;




     }
