I have recently ran into a problem that would not allow me to use DELETE and PUT requests into my .ashx file, so I added the proper verbs in order to allow that access. Now I am getting a 500 Internal Server Error. Here is my web.config for the handlers:
我最近遇到了一个问题，它不允许我使用DELETE和PUT请求到my .ashx文件中，所以我添加了适当的动词来允许访问。现在我得到了一个500的内部服务器错误。这是我的网站。配置处理程序:

Here is the httpHandlers:
这是httpHandlers:
<httpHandlers>
<add path="*.ashx" verb="*" type="System.Web.UI.SimpleHandlerFactory" validate="True" />
</httpHandlers>
Any ideas? I already went to IIS 7, went to Request Filtering, added .ashx file extension, set it to true and then in the HTTP Verbs section I added DELETE, POST, GET, HEADER, PUT.
什么好主意吗?我已经去了IIS 7，去请求过滤，添加。ashx文件扩展名，设置为true，然后在HTTP动词部分中添加了DELETE, POST, GET, HEADER, PUT。

Here is my .ashx file:

Line Number 1, Column 1:
I ONLY got this error AFTER i added verbs to my web.config so I could call DELETE and PUT requests into the httphandler
我只在添加了动词之后才得到这个错误。因此，我可以调用DELETE并将请求放入httphandler中。

That error normally means that your handler code is throwing an exception that is not being handled by your code. Take a look.
这个错误通常意味着您的处理程序代码抛出一个不被您的代码处理的异常。看一看。
