嗯,您正在抛出一个
未经授权的访问异常。如果没有捕获它的try catch
,代码将在那里崩溃。我认为你看到的异常就是你的异常。正如弗雷德里克所说,你抛出了一个错误,所以你得到了一个错误。如果只想实例化异常,不要使用throw
UnauthorizedAccessException uae=新的UnauthorizedAccessException(“某些消息”)
但同样,这只是创造了一个例外;一旦你扔出它,你就会得到你已经得到的信息
为什么不直接重定向?Response.Redirect(“~/AccessDeniedPage.aspx”,False)
如果确实想使用异常,可以继续按原样抛出异常,但也可以在Global.asax文件的Application_Error事件中处理异常。在Application_错误事件中,测试异常是否为UnauthorizedAccessException,如果是,则将用户重定向到AccessDeniedPage.aspx。应用程序的基本用法\u错误:
/**************************************************************************************************************************
Attempted to perform an unauthorized operation.
Exception Details: System.UnauthorizedAccessException: Attempted to perform an unauthorized operation.
ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6 and IIS 7, and the configured application pool identity on IIS 7.5) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.
