How to set web.config file to show full error message
提问by King Kong
I deployed my MVC-3 application on windows Azure. But now when I am requesting it through staging urlit shows me (Sorry, an error occurred while processing your request.). Now I want to see the full error message, by default it is hiding that because of some security reasons. I know that we can do this through web.config file. But how?

not sure if it'll work in your scenario, but try adding the following to your web.configunder <system.web>:
不确定它是否适用于您的场景，但请尝试将以下内容添加到您的web.configunder <system.web>：
<system.web>
<customErrors mode="Off" />
...
</system.web>
works in my instance.
在我的例子中工作。

If you're using ASP.NET MVC you might also need to remove the HandleErrorAttributefrom the Global.asax.cs file:
如果您使用的是 ASP.NET MVC，您可能还需要从 Global.asax.cs 文件中删除HandleErrorAttribute：
public static void RegisterGlobalFilters(GlobalFilterCollection filters)
{
filters.Add(new HandleErrorAttribute());
}

This can also help you by showing full details of the error on a client's browser.
这也可以通过在客户端浏览器上显示错误的完整详细信息来帮助您。
<system.web>
<customErrors mode="Off"/>
</system.web>
<system.webServer>
<httpErrors errorMode="Detailed" />
</system.webServer>
