C# - WHOIS 服务器提前关闭连接或不将整个响应发送到我的套接字？

Question

我正在发送服务器 172.217.2.142\r\n 并且它只响应:

#
# ARIN WHOIS data and services are subject to the Terms of Use
# available at: https://www.arin.net/whois_tou.html
#
# If you see inaccuracies in the results, please report at
# https://www.arin.net/public/whoisinaccuracy/index.xhtml
#

我的接收函数:

private string getResponse(Socket sock)
{
    byte[] buffer = new byte[1024];
    string result = string.Empty;
    int bytesReceived = 0;

    do
    {
        bytesReceived = sock.Receive(buffer, 0, buffer.Length, SocketFlags.None);
        Debug.Print("Bytes read:" + bytesReceived.ToString());
        result += Encoding.ASCII.GetString(buffer);
        Array.Clear(buffer, 0, buffer.Length);
    } while (bytesReceived > 0);

    return result;
}

一种流行的方法是使用 WebClient 从 URL 加载数据:

using (WebClient client = new WebClient())
{
    string value = client.DownloadString("url");            
}

返回的值是 arin.net 的 JSON 格式。
