Answer 1

如果你想学习C＃，最好先从一个控制台应用程序和一本好书开始。 ASP.NET MVC是一个需要自学的框架。 如果您不了解C＃，我认为它可能很难，您将无法学习C＃。

但是，您有一个问题我有一个答案：您可以根据视图中的用户角色显示或隐藏信息，如下所示。

@if (User.IsInRole("Admin"))
{
}
else if (User.IsInRole("Employee"))
{ 
}

在您的控制器中，您可以使用“授权属性”来防止未经授权的用户或其他角色的用户访问某些操作。

[Authorize(Roles = "Admin")]
public Action Result ShowAccounts()
{
}

您还应该在任何Controller上添加授权属性以防止匿名访问 - 例如在帐户控制器中。

[Authorize]
