I had the same problem. Definitely "Cors" doesn't work to me!
我有同样的问题。绝对“Cors”对我不起作用！
What I did to solve my problem with Cross Domain in WebApi it was remove Cors and change my web.config
我为解决 WebApi 中的跨域问题所做的工作是删除 Cors 并更改我的 web.config
If you insert the following lines inside your web.config, you'll have an WebApi with Cross Domain enabled.
如果您在 web.config 中插入以下几行，您将拥有一个启用了跨域的 WebApi。
<system.webServer>
<httpProtocol>
<customHeaders>
<add name="Access-Control-Allow-Origin" value="*" />
<add name="Access-Control-Allow-Methods" value="GET, POST, OPTIONS, PUT, DELETE" />
</customHeaders>
</httpProtocol>
</system.webServer>

I had this problem using NET 4.6.1 and after may hours of research removing this from web.config finally fixed the issue:
我在使用 NET 4.6.1 时遇到了这个问题，经过数小时的研究，从 web.config 中删除了这个问题，最终解决了这个问题：
<runtime>
<dependentAssembly>
<assemblyIdentity name="System.Net.Http" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-4.1.1.0" newVersion="4.1.1.0" />
</dependentAssembly>
</runtime>
