一个方法可以实现多个接口方法吗？

Question

These are two implementations of interface methods and as you can see, they do the same thing in this case .

public override IList<IDatastoreRequestParameter> GetReadByOwnerIdParameters(int id) {
    return new List<IDatastoreRequestParameter> {
        new DatastoreRequestParameter("@CustomerId", id)
    };
}

public override IList<IDatastoreRequestParameter> GetDeleteByOwnerIdParameters(int id) {
    return new List<IDatastoreRequestParameter> {
        new DatastoreRequestParameter("@CustomerId", id)
    };
}

However, as we use this interface everywhere, sometimes they are the same but they can also have different parameters returned in the implementation. I know I can just create a private method to return the same thing, I'm just curious to see if it's possible. My gut tells me no, but SO is smarter than my gut, so here I am.

Answer 1

You cannot make one method and tell the compiler/platform to use it when calling two different methods. As you said, you can create a private method that will handle the case and call that, but you do have to implement the methods in the interface separately.
