How to use System.Net.HttpClient to post a complex type?

Question

I have a custom complex type that I want to work with using Web API.

public class Widget
{
    public int ID { get; set; }
    public string Name { get; set;         


        

Answer 1

This is the code I wound up with, based upon the other answers here. This is for an HttpPost that receives and responds with complex types:

Task response = httpClient.PostAsJsonAsync(
                       strMyHttpPostURL,
                       new MyComplexObject { Param1 = param1, Param2 = param2}).ContinueWith((postTask) => postTask.Result.EnsureSuccessStatusCode());
                    //debug:
                    //String s = response.Result.Content.ReadAsStringAsync().Result;
                    MyOtherComplexType moct = (MyOtherComplexType)JsonConvert.DeserializeObject(response.Result.Content.ReadAsStringAsync().Result, typeof(MyOtherComplexType));
