如何在C＃中發布數值

Question

我正在嘗試使用HTTPclient發布到第三方api並獲得響應。 我可以發布到api，但是我遇到的問題是api需要programid為數字。 每當我嘗試使用此代碼發布時，它都會將其扔回，告訴我將programid設為數字。

我不知道如何通過ac＃/。net發送數字

using (var client = new HttpClient())
{
    var values = new Dictionary<string, string>
    {
       { "accesstoken", authtoken },
       { "programid", programid},
       { "email", person.Email },
       { "thirdparty1", person.ID.ToString() }
    };

    var content = new FormUrlEncodedContent(values);
    var response = client.PostAsync("url", content);
    var responseString = response.Result.Content.ReadAsStringAsync();
}

也許是WebClient？

using (var client = new WebClient())
            {
                var values = new Dictionary<string, string>
    {
       { "accesstoken", authtoken },
       { "programid", programid.ToString()},
       { "email", person.Email },
       { "thirdparty1", person.ID.ToString() }
    };

                var param = string.Join("&", values.Select(x => x.Key + "=" + x.Value).ToArray());

                client.Headers[HttpRequestHeader.ContentType] = "application/x-www-form-urlencoded";
                string HtmlResult = client.UploadString(URI, "POST", param);
            }

只要確保您沒有傳遞任何有趣的網址路由字符，例如？ 要么 ＆
