我正在尝试使用来自 Web API 的 HttpClient POST 一个 JsonObject.我不太确定如何解决这个问题，也找不到太多示例代码.

I'm trying to POST a JsonObject using HttpClient from Web API. I'm not quite sure how to go about this and can't find much in the way of sample code.

这是我目前所拥有的:

var myObject = (dynamic)new JsonObject(); myObject.Data = "some data"; myObject.Data2 = "some more data"; HttpClient httpClient = new HttpClient("myurl"); httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json")); HttpResponseMessage response = httpClient.Post("", ???);

我想我需要将我的 JsonObject 转换为 StreamContent 但我在这一步上被挂断了.

I think I need to cast my JsonObject as a StreamContent but I'm getting hung up on that step.

推荐答案

使用新版本的 HttpClient 而没有 WebApi 包，它将是:

With the new version of HttpClient and without the WebApi package it would be:

var content = new StringContent(jsonObject.ToString(), Encoding.UTF8, "application/json"); var result = client.PostAsync(url, content).Result;

或者如果你想要它async:

var result = await client.PostAsync(url, content);
