C#已经添加了System.Security.Cryptography依然没有MD5类

Question

 using App.Util;
using System;
using System.Collections.Generic;
using System.Net.Http;
using System.Security.Cryptography;

namespace App.Net
{
    public class HttpManage : Singleton<HttpManage>
    {
        private HttpClient httpClient;


        public void Init()
        {
            //AutomaticDecompression = DecompressionMethods.GZip  TODO 压缩
            var handle = new HttpClientHandler() { };
            httpClient = new HttpClient(handle);
        }



        public void PostAsyn(string protocol, string stream, string sign, StringDelegate callBack)
        {
            var content = new FormUrlEncodedContent(new Dictionary<string, string>()
            {
                {"protocol",protocol },
                {"steam",stream },
                {"sign",sign }
            });

        }



        public string MD5ForPHP(string stringToHash)
        {
            MD5 md5 = new MD5CryptoServiceProvider();
            byte[] output = md5.computehash(encoding.utf8.getbytes(stringtohash));
            return BitConverter.ToString(output).Replace("-", "");
        }


    }
}

似乎是mscorlib.dll库的问题，有点懵

一直是这种情况

Answer 1

嗯，解决办法最后是在Xamarin工程中扩展了一个MD5和原生一样的类。。。。
