访问控制器时发生堆栈溢出

Question

public ActionResult Index()
{
    var users = db.Users.Include(u => u.Users1).Include(u => u.User1);
    return View(users.ToList());
}

首先在 Visual Studio 中创建了一个 MVC / Entity 项目，DB。创建了两个控制器，一个命名为用户，另一个命名为任务。任务的页面视图工作正常，但每当我尝试访问用户视图页面时，我都会遇到此堆栈溢出。

首先删除第二个包含语句，然后查看错误是什么。如果这不起作用，您可以尝试这样的 Select Where 表达式。将 ToList() 添加到变量而不是返回。移动 ToList() 不会有所不同，但更容易调试。

public ActionResult Index()
    {
        var users = db.Users.Select().Where(u => u.Users1).ToList();
        return View(users);
    }
