How can I make a class both implement an Interface and inherit from another class

Question

I want my class to implement an interface and also get the additional properties from Auditable table. Can I do both? I have tried to do it here but I am getting an error in my IDE.

public partial class ObjectiveDetail : IEquatable<ObjectiveDetail>, AuditableTable
{
    ...
}

public abstract class AuditableTable : IAuditableTable
{
    ...
}

Answer 1

You must change

public partial class ObjectiveDetail : IEquatable<ObjectiveDetail>,  AuditableTable

to

public partial class ObjectiveDetail :   AuditableTable, IEquatable<ObjectiveDetail>

In C#, you can inherit one class and implement multiple interfaces and you must put class first .

Answer 2

公共子类：BaseClass，IInterface

Answer 3

是的，您可以两者都做，但是必须将基类放在首位：

public partial class ObjectiveDetail : AuditableTable, IEquatable<ObjectiveDetail>

Answer 4

首先是基类，然后是Interface，应该可以工作

Answer 5

没有什么可以阻止您实现接口和从同一类中的类继承，C＃仅不支持多重继承（从多个不同的类继承），因此您无需执行任何操作，它应该可以工作。
