Question

我很难让它发挥作用，但似乎做了意想不到的事情，出了什么问题？

string xmlToSend = "<elementOne xmlns=\"htt..mynamespace\">.......</elementOne>";
request = (HttpWebRequest)WebRequest.Create(address);
                request.Method = "POST";

                request.ContentType = "text/xml; charset=utf-8";
                request.Headers["Content-Length"] = xmlToSend.Length.ToString();

                _postData.Append(string.Format("{0}", xmlToSend));

                request.BeginGetRequestStream(new AsyncCallback(RequestReady), request);

.... }

和BeginGetRequestString：

   void RequestReady(IAsyncResult asyncResult)
            {
                HttpWebRequest request = asyncResult.AsyncState as HttpWebRequest;

                Debug.WriteLine("xml" + _postData.ToString());
                using (Stream stream = request.EndGetRequestStream(asyncResult))
                {
                    using (StreamWriter writer = new StreamWriter(stream))
                    {
                        writer.Write(_postData.ToString());
                        writer.Flush();
                    }
                }

                request.BeginGetResponse(new AsyncCallback(ResponseReady), request);
            }

我想要实现的是将请求的HTTPBODY设置为XML，就像在iOS中一样（setHTTPBody）......这是正确的方法吗？

您应该考虑远离HttpWebRequest并使用新的HTTPClient类。它们更直观，并提供新的Async样式架构的额外好处。

在Windows 7.5应用程序中使用新的HTTPClient库，

在https://www.nuget.org/packages/Microsoft.Net.Http维护HTTP客户端库（Install-Package Microsoft.Net.Http）

Nuget http://www.nuget.org/packages/Microsoft.Bcl.Async/（Install-Package Microsoft.Bcl.Async）

发送您的请求

public class SendHtmlData
{
 public async Task<T> SendRequest<T>(XElement xml)
    {
    var client = new HttpClient();

    var response = await client.PostAsync("https://requestUri", CreateStringContent(xml));

    var responseString = await response.RequestMessage.Content.ReadAsStringAsync();
    //var responseStream = await response.RequestMessage.Content.ReadAsStreamAsync();
    //var responseByte = await response.RequestMessage.Content.ReadAsByteArrayAsync();

    return JsonConvert.DeserializeObject<T>(responseString);
}

private HttpContent CreateStringContent(XElement xml)
{
    return new StringContent(xml.ToString(), System.Text.Encoding.UTF8, "application/xml");
}
}

在您的调用UI中，ViewModel执行与

类似的操作

public async Task SendHtml()
{
var xml = XElement.Parse("<elementOne xmlns=\"htt..mynamespace\">.......</elementOne>");

var result = await new SendHtmlData().SendRequest<MyDataClass>(xml);
}

发送带有帖子请求httphbrequest的xml
