How to disable the “Expect: 100 continue” header in WinRT's HttpWebRequest
提问by DVD
I'm developing an app that for legacy code reasons I can't upgrade for the new HttpClientso I'm using HttpWebRequests.
我正在开发一个应用程序，由于遗留代码的原因我无法升级新的，HttpClient所以我使用HttpWebRequests.
In .NET 4 we could deactivate the Expect header (on posts requests) using ServicePoint.Expect100Continueproperty, but on WinRT it's not available.
在 .NET 4 中，我们可以使用ServicePoint.Expect100Continue属性停用 Expect 标头（在发布请求上） ，但在 WinRT 上它不可用。
How can this be accomplished on WinRT?
这如何在 WinRT 上实现？
EDIT: System.Net.ServicePointManager.Expect100Continueis not available either.
编辑：System.Net.ServicePointManager.Expect100Continue也不可用。

It seems the only option you have it to override BeginGetRequestStream. HttpWebRequest has a private method MakeRequest and in it the Expect100Continue header is added to the request header collection.
它似乎是您覆盖 BeginGetRequestStream 的唯一选择。HttpWebRequest 有一个私有方法 MakeRequest，其中 Expect100Continue 标头被添加到请求标头集合中。

Put this is your webconfig.
把这是你的webconfig。

<settings>?
<servicePointManager expect100Continue="false"/>??
</settings>?
</system.net>
Also works! I use this in my webapplication. But answer above is equally as good!
也有效！我在我的网络应用程序中使用它。但上面的答案同样好！
