c#服务器端 传输json类型的数据使用gzip压缩怎么实现？

//MVC的
public class HelloController : Controller
{
// GET: Default
public void Index()
{
ResponseHeadersAdd("content-encoding", "gzip");
ResponseContentType = "application/json";
string json = "{\"status\":\"ok\"}";
var stream = new GZipStream(ResponseOutputStream, CompressionModeCompress);
byte[] jsonBuffer = UTF8EncodingUTF8GetBytes(json);
streamWrite(jsonBuffer, 0, jsonBufferLength);
streamClose();
}
}
//Webform就写在返回JSON的页面的Page_Load里面就行了
