有没有办法在抽象方法中将抽象类型定义为参数,并且在派生类中实现该方法时,您是否更改方法的类型以接受派生类型？

码:

public abstract class ProductBase
{
}

public class SomeProduct
    : ProductBase
{

}

public abstract class A
{
    protected abstract void addProduct(ProductBase p);
}

// This works
public class B : A
{        
    protected override void addProduct(ProductBase p)
    {
        // Do some work
    }
}

// This is what I'd like to do
public class C : A
{
    // Compiler error here because I have accepted a SomeProduct and not a ProductBase
    protected override void addProduct(SomeProduct p) …
