Answer 1

Try to use # insted of $ in client.BaseAddress. And check if tc object is not null.
I used Your code like this:
class Program
{
static void Main(string[] args)
{
using (HttpClient client=new HttpClient())
{
client.BaseAddress = new Uri(#"http://localhost:61737/api/presidents");
var json = JsonConvert.SerializeObject(new { name = "name", value = "value" });
var data = new StringContent(content: json,encoding: Encoding.UTF8,mediaType: "application/json");
var response = client.PostAsync(#"http://localhost:61737/api/presidents/post", data).GetAwaiter().GetResult();
var k = (response.Content.ReadAsStringAsync().GetAwaiter().GetResult());
}
}
}
And controller looks like this:
[RoutePrefix("api/presidents")]
public class PresidentsController : ApiController
{
public class oooo
{
public string Name { get; set; }
public string Value { get; set; }
}
[Route("post")]
public IHttpActionResult Post(oooo o)
{
return Ok(o);
}
}
and everything is working.
