Question

我正在尝试使用httpwebrequest使用以下代码基于this example here.下载xml文件现在它的部分工作原因是它不会下载所有xml文件的内容。知道为什么吗？

 public void download(String url)
    {
        HttpWebRequest request = HttpWebRequest.CreateHttp(url);
        request.AllowReadStreamBuffering = false;
        request.Method = "GET";
        request.BeginGetResponse(a =>
        {
            StringBuilder data=null;
            using (WebResponse response = request.EndGetResponse(a))
            {
                int expected = (int)response.ContentLength;

                try
                {
                    using (StreamReader reader = new StreamReader(response.GetResponseStream()))
                    {
                        int read = 0;
                        data = new StringBuilder(expected);
                        char[] buffer = new char[1024];

                        while ((read = reader.Read(buffer, 0, buffer.Length)) != 0)
                        {
                            data.Append(new string(buffer, 0, read));
                        }
                    }
                }
                catch (Exception ex)
                {
                    System.Diagnostics.Debug.WriteLine("exception caught: " + ex.Message);
                }
            }
            System.Diagnostics.Debug.WriteLine("Got \n " + data.ToString());
        }, null);
    }

如果你得到的只是XML，你可以使用XDocument.Load(stream)将结果加载到XDocument实例

您的问题可能与应用的编码有关，此方法应解决任何编码问题！

HttpWebRequest不下载所有数据
