C# 错误 401 - 无效的用户名或密码

Question

我正在尝试向 API 发出请求。当我使用邮递员发出请求时，它有效。但在 c# 中，它没有，它 returns 错误 401。我检查过，登录名和密码是正确的。谁能帮帮我？

代码：

public JsonResult Test()
{
    var document = new HtmlAgilityPack.HtmlDocument();

    var password = CalculateMD5Hash("******");

    var httpRequest =(HttpWebRequest)WebRequest.Create(string.Format("https://api.akna.com.br/emkt/int/integracao.php?User={0}&Pass={1}&XML={2}",
    "mail@mail.com",
     password,
    @"<main>
    <emkt trans='19.10'>
    <datainicial>2016-07-01 10:00:00</datainicial>
    <datafinal>2016-07-02 10:00:00</datafinal>
    </emkt>
    </main>"));

    httpRequest.Method = "POST";
    httpRequest.ContentType = "application/x-www-form-urlencoded";

    try
    {
    var httpWebResponse = (HttpWebResponse)httpRequest.GetResponse();

    var responseStream = httpWebResponse.GetResponseStream();

    if (responseStream != null)
    {
     var sr = new StreamReader(responseStream, Encoding.Default);
     document.LoadHtml(sr.ReadToEnd());
   }

   return Json(new { StatusCode = 200 }, JsonRequestBehavior.AllowGet);
   }
  catch (Exception ex)
  {
  return Json(new { StatusCode = 500, Erro = ex.Message }, JsonRequestBehavior.AllowGet);
 }
 }
