2 つのかなり単純なクラス (マップとゲーム) があり、このクエリを実行すると:
if(gameCollection.Any(g => g.NumPlayers <GameConstants.MAX_PLAYERS_PER_GAME))
エラーが表示されます: クラス MOMGame.GameObjects.Map をクラス MOMGame.GameObjects.Game に割り当てることはできません。既知の型がマップされたクラスから派生していることを確認してください。パラメータ名: タイプ
問題は何ですか？Mongo 2.2 に対して最新バージョンのドライバー (1.6.0.4624) を使用しています。
問題の 2 つのクラスは次のとおりです。
