Is it possible to create a HTTP HEAD request with the new HttpClient in .NET 4.5? The only methods I can find are GetAsync, DeleteAsync, PutAsync and PostAsync. I know that the HttpWebRequest-class is able to do that, but I want to use the modern HttpClient.

推荐答案

使用 SendAsync 法 HttpRequestMessage 这是利用人工 HttpMethod.Head 。

GetAsync ， PostAsync 等是的convenient包装的周围 SendAsync ;不太常见的HTTP方法，如 HEAD ，选项等，没有得到的包装。

GetAsync, PostAsync, etc are convenient wrappers around SendAsync; the less common HTTP methods such as HEAD, OPTIONS, etc, don't get a wrapper.
