HttpWebRequest保持活跃 - .net如何重用连接？

// 创建一个URI
Uri uri = new Uri("https://example.com");

// 创建一个HttpWebRequest请求
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(uri);

// 发送请求并获取响应
WebResponse response = request.GetResponse();

// 获取响应的内容
Stream dataStream = response.GetResponseStream();
StreamReader reader = new StreamReader(dataStream);
string responseFromServer = reader.ReadToEnd();

// 清理资源
reader.Close();
dataStream.Close();
response.Close();

// 现在可以重用请求连接
request = (HttpWebRequest)HttpWebRequest.Create(uri);
request.Method = "GET";
request.BeginGetResponse(new AsyncCallback(ReadWebResponse), request);
