Question

我有多个控制器，有一些常见的操作。我制作了通用控制器：

 public class FirstBaseController<TEntity> where TEntity : class, IFirst, new()
 public class SecondBaseController<TEntity> where TEntity : class, ISecond, new()

然后我想做这样的事情：

 public class MyController : FirstBaseController<First>, SecondBaseController<Second>

我知道C＃中不允许多类继承。你能告诉我其他方法吗？

唯一的选择是通过接口替换基类，并通过组合实现重用：

public interface IMyFirstSetOfMethods<TEntity> { /*... */ }
public interface IMySecondSetOfMethods<TEntity> { /*... */}

public class FirstImpl 
{

}

public class SecondImpl
{
}


public class MyController : IMyFirstSetOfMethods<First> , IMySecondSetOfMethods<Second>
{
    FirstImpl myFirstImpl = new FirstImpl();
    SecondImpl mySecondImpl = new SecondImpl();

    // ... implement the methods from the interfaces by simply forwarding to the Impl classes
}
