エンティティフレームワークを使用したオートマッテイング、初期化エラー

コードファーストを使用してモデルを生成するEF6 MVCアプリケーションがあります。私はモデルとそのモデルのビューモデル表現の間でAutoMapperを使用してマッピングを作成しようとしています。私はマッピングを行うときしかし、私はエラーが表示されます。エンティティフレームワークを使用したオートマッテイング、初期化エラー

Mapper not initialized. Call Initialize with appropriate configuration. If you are trying to use mapper instances through a container or otherwise, make sure you do not have any calls to the static Mapper.Map methods, and if you're using ProjectTo or UseAsDataSource extension methods, make sure you pass in the appropriate IConfigurationProvider instance.

私は間違いなくマッパーを初期化していますが、私はコンフィギュレーションが失敗している理由を把握することはできませんよ。この状況でAutoMapperを正常に使用するために私ができることについて誰かが助けてくれますか？ここで

は私がマッパーを設定し、初期化していますどのようにするコードです：ここで

var pTConnections = _db.PTConnections.Include(p => p.PTConnectionClass).ToList(); 

     Mapper.Initialize(cfg => 
     { 
      cfg.CreateMap<PTConnection, PTConnectionViewModel>() 
       .AfterMap((s, d) => { foreach (var i in d.PTCredentialAssignments) i.PTConnection = d; }); 

      cfg.CreateMap<PTCredentialAssignment, PTCredentialAssignmentViewModel>() 
       .ForMember(m => m.PTCredential, opt => opt.Ignore()) 
       .ForMember(m => m.PTConnection, opt => opt.Ignore()); 

      cfg.CreateMap<PTVendor, PTVendorViewModel>() 
       .ForMember(m => m.PTCredentials, opt => opt.Ignore()) 
       .ForMember(m => m.PTConnections, opt => opt.Ignore()); 

      cfg.CreateMap<PTCredential, PTCredentialViewModel>(); 

      cfg.CreateMap<PTConnectionClass, PTConnectionClassViewModel>() 
       .ForMember(m => m.PTConnections, opt => opt.Ignore()); 

      cfg.CreateMap<PTConnectionContactAssignment, PTConnectionContactAssignmentViewModel>() 
       .ForMember(m => m.PTConnection, opt => opt.Ignore()); 

     }); 

    var dest = Mapper.Map<List<PTConnection>, List<PTConnectionViewModel>>(pTConnections);

@Amyが、私は、あなたが提案の修正を行ったが、私は今、新たなエラーが発生します。 _ "エラーマッピングタイプを \ rを\ nは\ rを\ nMappingタイプ：。\ rを\ nList'1 - > List' 1 \ r \ nSystem.Collections.Generic.List'1 [[PTApp.Models.PTConnection、PTApp、Version = 1.0.0.0、Culture =ニュートラル、PublicKeyToken = null]] - > System.Collections.Generic.List'1 "[_ PTApp.ViewModels.PTConnectionViewModel、PTApp、Version = 1.0.0.0、Culture = neutral、PublicKeyToken = null]]"} _ – silverbullettruck2001

これは、それぞれのプロパティタイプもマッピングする必要があるからです。 'PTConnectionClass'は' PTConnectionClassViewModel'にマップされなければならないなど、各プロパティをどのようにマップするかは分かりません。すべてのプロパティタイプがマップされると、メインオブジェクトをマップできます。 – Amy

さらに、その例外を展開して内部例外を調べると、マップできないプロパティが表示されます。 – Amy

あるタイプから別のタイプへマップを作成するだけです。あるタイプのリストから別のタイプのリストへのマップを作成しないでください。 Automapperは自動的にコレクションを処理できます。実際に

、あなたが実際にBへAをマッピングする方法Automapperを告げずList<B>にList<A>をマッピングする方法Automapperを言っています。以下に、あなたの登録を変更する：あなたはまだList<PTConnection>List<PTConnectionViewModel>にちょうど良い、だけでなく、他のほとんどのコレクション型をマップすることができ

Mapper.Initialize(cfg => 
{ 
    cfg.CreateMap<PTConnection, PTConnectionViewModel>(); 
});
