ジェネリックスとベースクラス

Question

私は自分のプロジェクトをセットアップするのに苦労しています。

public WebSocketResponse HandleRequest(RequestDto request, GameSessionServer server) 
    { 
     TrySetThreadCulture(request); 
     EnsureUserStoredInSession(server.SessionContext, false, SlotIsEngineRNG(server.SessionContext.SystemGameId)); 

     // custom request handling 
     WebSocketResponse wsr = HandleRequestInternal(request, server); 

     // save the last handler 
     server.SessionContext.Items[typeof(WebSocketHandler)] = this; 
     return wsr; 
    } 

はそれがRequestDto基本クラスのパラメータまたはあるべき：今、私はベースソケットハンドラハンドラ（クラスの一部）を持っている.. JSONリクエストの処理および登録されているハンドラを担当するクラス - 私はGameSessionServerを持っていますジェネリックRequestDto ??????私はここのような特定のタイプにRequestDtoのキャストん具体的なハンドラで ：

protected override WebSocketResponse HandleRequestInternal(RequestDto request, GameSessionServer server) 
    { 
     CasinoSpinRequestDto spinRequest = request as CasinoSpinRequestDto; 

     int TotalBetInCents = (spinRequest.SpinType != "free") ? spinRequest.TotalBet : 0; 
     JsonResult JR = null; 

     CasinoSpinResponseDto spinResponse = new CasinoSpinResponseDto(); 
     switch (spinRequest.SpinType) 
     { 
      case "regular": 
       JR = PlayBetSpin(spinRequest, server); 
       break; 
      case "free": 
       JR = PlayFreeSpin(spinRequest, server.SessionContext); 
       break; 
     } 

     // set balance in cents 
     spinResponse.Credit = JR.BalanceInCents; 

     SlotEngineRNG engineRNG; 
     sbyte[,] wheels = (JR is SpinJsonResult) ? ((SpinJsonResult) JR).Wheels : ((BonusJsonResult) JR).FreeSpin.Wheels; 
     int rsId = (JR is SpinJsonResult) ? 0 : ((BonusJsonResult) JR).FreeSpin.ReelId; 

     if (SlotIsEngineRNG(server.SessionContext.SystemGameId, out engineRNG)) 
     { 
      GameSettingInfo gsi = DataBuffer.Instance.GetGameSetting(server.SessionContext.UserGroupId, (int) server.SessionContext.SystemGameId); 
      spinResponse.Results = CalculateWheelPositionsRNG(wheels , rsId , engineRNG, gsi); 
     } else 
     { 
      int[] pos; 
      PosHoldersFactory.GetSlotPositions(server.SessionContext.SystemGameId, wheels, rsId, out pos); 
      spinResponse.Results = pos; 
     }

だから、戦略パターンを使用することができます。

interface IWebRequestHandler 
{ 
    bool CanHandle(RequestDto request); // assuming the request dto is the base class 

    WebSocketResponse Handle(RequestDto request, GameSessionServer server); 
} 

class CasinoSpinRequestHandler : IWebRequestHandler 
{ 
    bool CanHandle(RequestDto request) 
    { 
     return request is CasinoSpinRequestDto; 
    } 

    WebSocketResponse Handle(RequestDto request, GameSessionServer server) 
    { 
     var spinRequest = request as CasinoSpinRequestDto; 

     if (spinRequest == null) throw new ArgumentNullException("Incorrect usage of the handler"); 

     // do your specific spin request code here 
    } 
} 

public WebSocketResponse HandleRequest(RequestDto request, GameSessionServer server) 
{ 
    TrySetThreadCulture(request); 
    EnsureUserStoredInSession(server.SessionContext, false, SlotIsEngineRNG(server.SessionContext.SystemGameId)); 

    var handlerStrategies = this.GetType().Assembly.GetTypes().Where(x => typeof(IWebRequestHandler).IsAssignableFrom(x)).Select(x => Activator.CreateInstance(x)).Cast<IWebRequestHandler>().ToList(); 
    // the above is poor man DI, you can just put in the constructor ctor(IEnumerable<IWebRequestHandler>) 
    // if your DI supports it, otherwise you can abstract the code above to a 
    // static class so it only gets called once. 

    var handler = handlerStrategies.FirstOrDefault(x => x.CanHandle(request)); 

    if (handler == null) throw new Exception("Unable to handle this particular request"); 

    // custom request handling 
    var wsr = handler.Handle(request, server); 

    // the consuming of the handler can also be abstracted to a delegate class 
    // which merely has the responsibility of sorting out which handler to use 

    // save the last handler 
    server.SessionContext.Items[typeof(WebSocketHandler)] = this; 
    return wsr; 
} 

あなたはより多くの明確化が必要な場合は、単にどの部分について具体的に。
