asp.net-mvc - 在控制器中捕获异常

Question

似乎如果控制器内部发生异常，视图引擎将不会转到预期的视图，即使“异常”被捕获在 try-catch 块中？

或者我在这里遗漏了一些东西：

public ActionResult MyController(int? param1, DateTime? param2)
{
    MyModel model = new MyModel();
    try
    {
        model = new MyModel();

        //AN ERROR HAPPENS HERE (so the code goes to catch the Exception):
        model.Connection.Initialize();
    }
    catch (Exception ex)
    {
        ViewBag.ErrorMessage = ex.Message;
    }
    //when I put a break point I get to this following line, however, "MyView" is never displayed!?
    return PartialView("MyView", model);
}

之后，您可能会在您认为的某个地方遇到另一个异常。查看浏览器页面上显示的堆栈跟踪并修复它。
