インターフェースを派生したクラスを取得する

Posted at

抽象クラスの派生先は以下でとれる

code.cs
//Tは抽象クラス
var types = Assembly.GetAssembly(typeof(T))
                   .GetTypes()
                   .Where(type =>
               {
                   return type.IsSubclassOf(typeof(T))
                    && !type.IsInterface
                    && !type.IsAbstract;
               });

が、インターフェースの派生先はこれでは取れないので ↓

code.cs
//Tはインターフェース
var types = Assembly.GetAssembly(typeof(T))
                    .GetTypes()
                    .Where(type =>
                {
                    return typeof(T).IsAssignableFrom(type)
                     && !type.IsInterface
                     && !type.IsAbstract;
                });

抽象クラスとインターフェースは除外している
