如何实现工作包含新IdentityUser一股股 [英] How to implement a Unit of work containing the new IdentityUser
问题描述
我想知道什么是对的UserManager添加到我的工作单元的最佳途径。我应该使用IUstrore接口，并在我的控制器中添加新的UserManager？如果我只是使用的UserManager在我的UnitOfWork或者我应该做不同的事情？
下面是两个概念我对我的工作和控制器实现的单位。
公共类UnitOfWorkPds：IUnitOfWorkPds，IDisposable接口
{
私人ApplicationDbContext语境=新ApplicationDbContext（）;
私人IUserStore＆LT; ApplicationUser＆GT; userStore; 公共IUserStore＆LT; ApplicationUser＆GT; UserStore
{
得到
{
如果（this.userStore == NULL）
{
this.userStore =新UserStore＆LT; ApplicationUser＆GT;（上下文）;
} 返回userStore;
}
}
}//接口
公共接口IUnitOfWorkPds
{
无效保存（）;
无效的Dispose（）; IUserStore＆LT; ApplicationUser＆GT; UserStore {搞定; }
}
控制器：
VAR Umanager =新的UserManager＆LT; ApplicationUser＆GT;（unitOfWorkPds.UserStore）;
Umanager.Dispose（）;
选项2创建工作单位的UserManager。
公共类UnitOfWorkPds：IUnitOfWorkPds，IDisposable接口
{
私人ApplicationDbContext语境=新ApplicationDbContext（）;
私人的UserManager＆LT; ApplicationUser＆GT;的UserManager; 公众的UserManager＆LT; ApplicationUser＆GT;的UserManager
{
得到
{ 如果（this.userManager == NULL）
{
this.userManager =新的UserManager＆LT; ApplicationUser＆GT;（新UserStore＆LT; ApplicationUser＆GT;（上下文））;
} 返回的UserManager;
}
}
}公共接口IUnitOfWorkPds
{
无效保存（）;
无效的Dispose（）;
的UserManager＆LT; ApplicationUser＆GT; {的UserManager获得; }
}
控制器：
VAR UManager = unitOfWorkPds.UserManager
Umanager.Dispose（）;
请注意：我使用的Asp.net MVC5，C＃，实体框架6.也是我在工作单位等信息库，但我离开他们去关注用户执行
无论哪种方式，工作在我第一次收到此警告，但为了摆脱我叫this.userStore.Dispose错误的（）;下面的错误是我的执行处置。目前，我打电话给我的工作单位处置的userStore。我也创建了用户管理器为这个userStore在我的控制器，我也呼吁处置的UserManager我的控制器内。

解决方案您需要查看的UnitOfWork模式。
工作模式和持久性的无知单位有关错误的问题，确保你有以下code片段。
- 的错误点从UnitOfWorkPds处分的类中调用Dispose。
- 您在呼唤userStroe其中应的UserManager
- 以下片段缺失实施IUnitOfWorkPds的

{

私人的UserManager＆LT; ApplicationUser＆GT;的UserManager;
公众的UserManager＆LT; ApplicationUser＆GT;的UserManager

}
返回的UserManager;
}

//一次性类型实现一个终结。

}
}I am wondering what is the best way to add the UserManager to my Unit of work. Should I use the IUstrore interface and add a new UserManager in my controller? Should I just use UserManager in my UnitOfWork or should I do something different?
Here is two ideas I had for my unit of work and controller implementation.
public class UnitOfWorkPds : IUnitOfWorkPds, IDisposable { private ApplicationDbContext context = new ApplicationDbContext(); private IUserStore<ApplicationUser> userStore; public IUserStore<ApplicationUser> UserStore { get { if (this.userStore == null) { this.userStore = new UserStore<ApplicationUser>(context); } return userStore; } } } //interface public interface IUnitOfWorkPds { void Save(); void Dispose(); IUserStore<ApplicationUser> UserStore { get; } }Controller :
var Umanager = new UserManager<ApplicationUser>(unitOfWorkPds.UserStore); Umanager.Dispose();Option 2 create the usermanager in the unit of work.
public class UnitOfWorkPds : IUnitOfWorkPds, IDisposable { private ApplicationDbContext context = new ApplicationDbContext(); private UserManager<ApplicationUser> userManager; public UserManager<ApplicationUser> UserManager { get { if (this.userManager == null) { this.userManager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(context)); } return userManager; } } } public interface IUnitOfWorkPds { void Save(); void Dispose(); UserManager<ApplicationUser> UserManager { get; } }Controller :
var UManager = unitOfWorkPds.UserManager Umanager.Dispose();Note: I am using Asp.net MVC5, c#, Entity Framework 6. Also I have other repositories in my unit of work but I left them out to focus on the User implementation.
Either way works at first I receive this warning but to get rid of the error I called this.userStore.Dispose(); Below the error is my implementation of Dispose. Currently i'm calling dispose on the userStore in my Unit of Work. I also create a user manager for this userStore in my controller and I am also calling dispose on userManager inside my controller.
CA2213 Disposable fields should be disposed 'UnitOfWorkPds' contains field 'UnitOfWorkPds.userManager' that is of IDisposable type: 'UserManager'. Change the Dispose method on 'UnitOfWorkPds' to call Dispose or Close on this field. UnitOfWorkPds.cs 96
private bool disposed = false; protected virtual void Dispose(bool disposing) { if (!this.disposed) { if (disposing) { if(this.userStore != null) { this.userStore.Dispose(); } context.Dispose(); } } this.disposed = true; } public void Dispose() { Dispose(true); GC.SuppressFinalize(this); }
解决方案You need to review the UnitOfWork Pattern. The Unit Of Work Pattern And Persistence Ignorance
For the issue of error make sure you have following code snippets.
- The error points to calling Dispose from inside the Dispose of UnitOfWorkPds class.
- You are calling userStroe which shall be userManager
- Following snippets is missing implementation of IUnitOfWorkPds
public class UnitOfWorkPds : IUnitOfWorkPds, IDisposable { private ApplicationDbContext context = new ApplicationDbContext(); private UserManager<ApplicationUser> userManager; public UserManager<ApplicationUser> UserManager { get { if (this.userManager == null) { this.userManager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(context)); } return userManager; } } protected virtual void Dispose(bool disposing) { if (disposing) { if(this.userManager != null) { this.userManager.Dispose(); } context.Dispose(); } this.disposed = true; } public void Dispose() { Dispose(true); GC.SuppressFinalize(this); } // Disposable types implement a finalizer. ~UnitOfWorkPds() { Dispose(false); } }
