Request.CreateErrorResponse在哪里? [英] Where is Request.CreateErrorResponse?

问题描述

我在

I saw it in this blog post, but that doesn't actually say how to "enable" it. And it seems that by default it isn't enabled.

我知道这是一种扩展方法，定义如下:

I know it's an extension method, as defined here: http://msdn.microsoft.com/en-us/library/hh835786(v=vs.108).aspx but how do I get access to it? If I type Request.CreateErrorResponse then the compiler doesn't recognize it.

我已经在使用System.Net.Http .

I'm already using System.Net.Http.

推荐答案

您仍在使用预发行版还是发行版?许多扩展直到发行版才出现，并且在早期版本的webapi中不存在.我不确定这是否是其中之一，但这可能是导致您出现问题的原因.

Are you still using pre-release or release version? There were a number of extensions that did not appear until just before the release and did not exist in earlier versions of the webapi release. I am unsure if this was one of them, but it may be what is causing your problem.
