如何將一個較大的JSON對象直接序列化爲HttpResponseMessage流？

Question

有沒有什麼方法可以將大的JSON對象直接流到HttpResponseMessage流？

這裏是我現有的代碼：

 Dictionary<string,string> hugeObject = new Dictionary<string,string>(); 
     // fill with 100,000 key/values. Each string is 32 chars. 
     HttpResponseMessage response = new HttpResponseMessage(HttpStatusCode.OK); 
     response.Content = new StringContent(
      content: JsonConvert.SerializeObject(hugeObject), 
      encoding: Encoding.UTF8, 
      mediaType: "application/json"); 

的正常工作爲更小的物體。但是，調用JsonConvert.SerializeObject（）將對象轉換爲字符串的過程會導致大對象的內存峯值出現問題。

我想做相當於what's described here for deserialization。

你可以嘗試使用PushStreamContent和寫入與JsonTextWriter：

HttpResponseMessage response = new HttpResponseMessage(HttpStatusCode.OK); 
response.Content = new PushStreamContent((stream, content, context) => 
{ 
    using (StreamWriter sw = new StreamWriter(stream, Encoding.UTF8)) 
    using (JsonTextWriter jtw = new JsonTextWriter(sw)) 
    { 
     JsonSerializer ser = new JsonSerializer(); 
     ser.Serialize(jtw, hugeObject); 
    } 
}, "application/json");
