在.NET 4.5.1中发布到ASP.NET WebApi 2

Question

How can I POST a complex type to a Web Api 2 controller action, from a C# client? I see a lot of information about it but for older versions of the framework. What's the correct way to do it in .NET 4.5.1?

At the moment I have:

using (var client = new HttpClient())
{
    client.BaseAddress = new Uri("http://localhost:60892/");
    client.DefaultRequestHeaders.Accept.Clear();
    client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

    //client.PostAsJsonAsync() doesn't seem to exist or I am missing something
    //client.PostAsync() can't find a way to post a complex type    

    if (response.IsSuccessStatusCode)
    {

    }
}

You will find the PostAsJsonAsync extension method in the Micorosft ASP.NET Web API 2.1 Client NuGet package .

Nevertheless, if you set the HttpContent appropriately the PostAsync method should work. An example can be found in this discussion .
