如何在WinRT的HttpWebRequest中禁用“Expect：100 continue”标头

Question

I'm developing an app that for legacy code reasons I can't upgrade for the new HttpClient so I'm using HttpWebRequests .

In .NET 4 we could deactivate the Expect header (on posts requests) using ServicePoint.Expect100Continue property, but on WinRT it's not available.

How can this be accomplished on WinRT?

EDIT: System.Net.ServicePointManager.Expect100Continue is not available either.

Answer 1

        var c = new HttpClient();
        c.DefaultRequestHeaders.ExpectContinue = false;

Answer 2

Put this is your webconfig.

 <system.net>
 <settings> 
 <servicePointManager expect100Continue="false"/>  
 </settings> 
 </system.net>

Also works! I use this in my webapplication. But answer above is equally as good!

Answer 3

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.
