由于继承了不同类的值

问题描述

由于获得了一个类的值，并且该值将其显示在另一个类中.例如:
我有一个名为产品"的类，并且有一个名为价格"的字段.在另一个名为交易"的类中，我希望所选产品的价格出现.
感谢您的帮助.

---编辑kschuler:删除了代码块

Since a value of a class obtains and that it shows it in other one. For example:
I have a class called Product and there I have a Field called Price. In another class called Transaction I want that the price appears for the selected product.
I am grateful for any help.

---EDIT kschuler: removed code block

推荐答案

class Transaction
{
  private Product _purchasedProduct;
  public Product PurchasedProduct
  {
    get
    {
      return this._purchasedProduct;
    }
    set
    {
      this._purchasedProduct = value;
    }
  }
}

如果是这样，那么您可以这样做:

If that''s the case, then you could just do:

Transaction newTransaction = new Transaction();
newTransaction.PurchasedProduct = new Banana();
Console.WriteLine(newTransaction.PurchasedProduct.Price.ToString());
