在webrequest上检索Unicode文本

Question

我使用以下代码发送网络请求：

WebRequest request = WebRequest.Create(url);
// If required by the server, set the credentials.
request.Credentials = CredentialCache.DefaultCredentials;
// Get the response.
WebResponse response = request.GetResponse();
// Display the status.
Console.WriteLine(((HttpWebResponse)response).StatusDescription);
// Get the stream containing content returned by the server.
Stream 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.
Response.Write(responseFromServer);

但我收到了错误的数据，例如＆amp; F S| “ i （

解决方案是什么？
