HttpClient PostAsync到WebApi-返回500，但不会引发异常）

Question

I'm making a call to a web api service like this:

var response = client.PostAsync("http://localhost:8080/api/values", new FormUrlEncodedContent(new[] {new KeyValuePair<string, string>("a", "b"),}))
                     .Result;

Result is a

"500 internal server error"

No exception is thrown (even though I've set VS to Break when CLR exceptions are thrown)

I there any way I can force VS to bubble up the underlying exception?

Answer 1

There is no underlying exception, that's why you can't bubble it up. However, if you want to create one you can call

 response.EnsureSuccessStatusCode();

If the response code is a 4xx or 5xx then it will throw.
