[英]Hosting an Asp.Net MVC 4 application on windows server 2012 with IIS8 from a Local Machine
[英]ASP.NEt MVC 2 application error on IIS7 works fine on local machine
我的ASP.NET MVC2应用程序是使用1. VS 2010开发的。LinqTo SQL for Models
这是呼叫控制器代码:
namespace CallTrackMVC.Controllers
{
public class CallController : Controller
{
private CallTrackRepository repository;
public CallController():this(new CallTrackRepository())
{
}
public CallController(CallTrackRepository newRepository)
{
repository = newRepository;
}
}
}
浏览“呼叫创建”页面时,IIS7上的错误为
NullReferenceException: Object reference not set to an instance of an object.]
CallTrackMVC.Models.ExecOfficeDataContext..ctor() in C:\ClearCase\rartadi_view\STS_Dev_TEST\CallTrackMVC\Models\ExecOffice.designer.cs:71

Global.asax中的代码是
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
RegisterRoutes(RouteTable.Routes);
}
任何建议都会有很大帮助。
没有界面时,无需使用“穷人DI”。
只需使您的代码看起来像这样:
public class CallController : Controller
{
private readonly CallTrackRepository _repository;
public CallController()
{
_repository= new CallTrackRepository();
}
}
这应该可以解决您的问题。
