我可以通过创建默认的ASP.NET MVC应用程序并添加上述代码来重现问题.奇怪的是,这个代码在我的旧主机上工作正常,它只会在我的新(共享)主机上崩溃.如果我的代码中有这些事件处理程序,我得到这个错误：
Server Error in ‘/’ Application.
Object reference not set to an
instance of an object. Description:
An unhandled exception occurred during
the execution of the current web
request. Please review the stack trace

我尝试使用Softsys进行故障排除,但是它们并不是很有帮助,基本上他们只是确认我已经在我的管理控制面板中打开了“ASP.NET管道(MVC)”功能.
有人可以
解决方法
所以你的代码应该是这样的：
public class MySmartApp: HttpApplication{
public override void Init(){
this.BeginRequest += new EventHandler(MvcApplication_BeginRequest);
this.EndRequest += new EventHandler(MvcApplication_EndRequest);
}
protected void Application_Start(){
RegisterRoutes(RouteTable.Routes);
}
}
或者这样：
public class MySmartApp: HttpApplication{
public MySmartApp(){
this.BeginRequest += new EventHandler(MvcApplication_BeginRequest);
this.EndRequest += new EventHandler(MvcApplication_EndRequest);
}
protected void Application_Start(){
RegisterRoutes(RouteTable.Routes);
}
}
