我正在尝试.Contains()在自定义对象列表上使用该函数

这是清单:

List<CartProduct> CartProducts = new List<CartProduct>();

而且CartProduct:

public class CartProduct
{
    public Int32 ID;
    public String Name;
    public Int32 Number;
    public Decimal CurrentPrice;
    /// <summary>
    /// 
    /// </summary>
    /// <param name="ID">The ID of the product</param>
    /// <param name="Name">The name of the product</param>
    /// <param name="Number">The total number of that product</param>
    /// <param name="CurrentPrice">The currentprice for the product (1 piece)</param>
    public CartProduct(Int32 ID, String Name, Int32 Number, Decimal CurrentPrice)
    {
        this.ID = ID;
        this.Name = Name; …

如果我有一个类型的对象MyBull和一个List<MyBull> orig:

// Just an example
MyBull x = getMeTheObjectWithIdFromDB(9);

orig.add(x);

// Again same? data object
MyBull y = getMeTheObjectWithIdFromDB(9);

为什么这是假的呢？

// This is false, even though all the properties
// of x and y are the same.
orig.Contains<MyBull>(y);
