这是我正在使用的代码:

// create a request
HttpWebRequest request = (HttpWebRequest)
WebRequest.Create(url); request.KeepAlive = false;
request.ProtocolVersion = HttpVersion.Version10;
request.Method = "POST";


// turn our request string into a byte stream
byte[] postBytes = Encoding.UTF8.GetBytes(json);

// this is important - make sure you specify type this way
request.ContentType = "application/json; charset=UTF-8";
request.Accept = "application/json";
request.ContentLength = postBytes.Length;
request.CookieContainer = Cookies;
request.UserAgent = currentUserAgent;
Stream requestStream = request.GetRequestStream();

// now send it
requestStream.Write(postBytes, 0, postBytes.Length);
requestStream.Close();

// grab te response and print it out …

我正在尝试将内容发布到我的服务器。这就是我过去一直这样做的方式，直到我不得不使用字符串以外的对象为止。

using (HttpClient client = new HttpClient())
{
    client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue(authType, tokens);
    var postParams = new Dictionary<string, object>();

    postParams.Add("string", string);
    postParams.Add("int", string);
    postParams.Add("datetime", DateTime);
    postParams.Add("datetime", DateTime);
    postParams.Add("Match", Match);
    postParams.Add("TicketId", token);

    using (var postContent = new FormUrlEncodedContent(postParams.ToDictionary()))
    {
        var myContent = JsonConvert.SerializeObject(postParams);
        var buffer = System.Text.Encoding.UTF8.GetBytes(myContent);
        var byteContent = new ByteArrayContent(buffer);
        byteContent.Headers.ContentType = new MediaTypeHeaderValue("application/json");

        using (HttpResponseMessage response = await client.PostAsync(@"http://url/api", byteContent))
        {
            response.EnsureSuccessStatusCode(); // Throw if httpcode is an error
            using (HttpContent content = response.Content)
            {
                string result = …
