C# StringContent 构建JSON格式数据

直接上代码，使用StringContent Post Json结构数据

 StringContent stringContent = new StringContent(myObjectAsJSON, Encoding.UTF8, "application/json");
    using (HttpClient httpClient = new HttpClient())
    {
        httpClient.BaseAddress = new Uri(endpointUri);
        using (HttpResponseMessage responseMessage = await httpClient.PostAsJsonAsync(endpointDirectory, stringContent).ConfigureAwait(false))
        {
            // Do something
        }
    }
