通过构造函数访问 AccountController 中的存储库
我正在使用实现 ASP.NET 成员资格提供程序的 MVC AccountController。 我有一个包含所有数据库访问权限的存储库，其中我添加了一个返回国家/地区列表的国家/地区属性。我想在注册页面添加一个国家/地区下拉列表，因此我需要能够从我的存储库获取此数据并将其传递到视图。 我一直在其他控制器中使用构造函数注入，但我不知道如何将其应用于现有的 AccountController。
// This constructor is used by the MVC framework to instantiate the controller using
// the default forms authentication and membership providers.
public AccountController()
: this(null, null)
{
}
// This constructor is not used by the MVC framework but is instead provided for ease
// of unit testing this type. See the comments at the end of this file for more
// information.
public AccountController(IFormsAuthentication formsAuth, IMembershipService service)
{
FormsAuth = formsAuth ?? new FormsAuthenticationService();
MembershipService = service ?? new AccountMembershipService();
}
我可以更改现有的 AccountController 构造函数来访问我的存储库吗？
I am using the MVC AccountController that implements the ASP.NET Membership Provder.
I have a repository with all my database access in which I have added a Countries property that returns a list of countries. I want to add a country dropdown to the Register page so I need to be able to get this data from my repository and pass it to the View.
I have been using contructor injection in my other controllers but I dont know how to apply this to the existing AccountController.
// This constructor is used by the MVC framework to instantiate the controller using
// the default forms authentication and membership providers.
public AccountController()
: this(null, null)
{
}
// This constructor is not used by the MVC framework but is instead provided for ease
// of unit testing this type. See the comments at the end of this file for more
// information.
public AccountController(IFormsAuthentication formsAuth, IMembershipService service)
{
FormsAuth = formsAuth ?? new FormsAuthenticationService();
MembershipService = service ?? new AccountMembershipService();
}
Can I change the existing AccountController constructor to access my repository?

在 IoC 引擎中注册服务，然后删除默认构造函数。
Register the services in your IoC engine and then remove the default constructor.
如果您已经使用 ninject 注册了存储库，则应该能够将第三个参数添加到控制器的构造函数中。我看到你之前关于 ninject 的评论，但我没有使用 NinjectModule。如果您使用的是 MVC 3，建议您查看 nuget (http://nuget.codeplex.com) 并下载 Ninject.MVC3 包将 AppStartNinjectMvc3 类添加到您的项目中，您可以在其中使用 kernel.Bind 方法注册服务：
希望这会有所帮助。
If you have already registered your repository with ninject, you should be able to just add a third parameter to the constructor of the controller. I saw your earlier comment about ninject, but I'm not using NinjectModule. If you're using MVC 3, would suggest that you take a look at nuget (http://nuget.codeplex.com) and download the Ninject.MVC3 packge which adds a AppStartNinjectMvc3 class to your project where you can register services with the kernel.Bind methods:
Hope this helps.
如果您使用 MVC2，您应该看看 http://mvcstarter.codeplex.com/ 它也使用 Ninject 。就像@Johan所说，您只需将参数并将其绑定到global.asax.cs中即可。
希望有帮助！
If your using MVC2 you should take a look at http://mvcstarter.codeplex.com/ it's also using Ninject. Like @Johan said you simply have to put the parameter and bind it in the global.asax.cs.
Hope it helps!
