Question

我正在编写一个简单的服务器端应用程序，它将请求发送到远程休息服务。当我使用此代码示例通过我的代码发送它时：

// Create a request using a URL that can receive a post. 
WebRequest request = WebRequest.Create(url);
// Set the Method property of the request to POST.
request.Method = "POST";

// Create POST data and convert it to a byte array.
var paramsBuilder = new StringBuilder();
foreach (var param in parameters)
{
    paramsBuilder.AppendFormat("&{0}={1}", param.Key, param.Value);
}
paramsBuilder.Length--;

byte[] byteArray = Encoding.UTF8.GetBytes(paramsBuilder.ToString());
// Set the ContentType property of the WebRequest.
request.ContentType = "application/x-www-form-urlencoded";
// Set the ContentLength property of the WebRequest.
request.ContentLength = byteArray.Length;
// Get the request stream.
Stream dataStream = request.GetRequestStream();
// Write the data to the request stream.
dataStream.Write(byteArray, 0, byteArray.Length);
// Close the Stream object.
dataStream.Close();
// Get the response.
WebResponse response = request.GetResponse();
// Get the stream containing content returned by the server.
dataStream = response.GetResponseStream();
// Open the stream using a StreamReader for easy access.
StreamReader reader = new StreamReader(dataStream);
// Read the content.
string responseFromServer = reader.ReadToEnd();
// Display the content.
Console.WriteLine(responseFromServer);
// Clean up the streams.
reader.Close();
dataStream.Close();
response.Close();
return responseFromServer;

我退回了部分结果。内容没有修剪，只是部分。当我通过像hurl.it这样的服务发送相同的请求时，我得到了完整的回复。

可能导致什么原因？

可能是因为服务器在响应中使用的编码

解释了这一点 “StreamReader使用默认编码（UTF8），它可能与您在StreamReader中读取的字节的编码不匹配。”

发送http post请求会返回部分结果
