C＃序列化嵌套类 [英] c# serialize nested class

问题描述

我试图序列化订单的虚拟集合，每个订单包含的产品。该集合序列化的罚款，但为了内部的例如产品性能被错过。

I'm trying to serialize a dummy collection of orders, where each order contains a product. The collection is serializing fine, but the example product properties inside the order are being missed.

[XmlRoot("Orders")]
public class OrderCollection : ICollection<Order>
{
    private static List<Order> _orders;

    private List<Order> Orders
    {
        get
        {
            if(_orders == null)
            {
                _orders = new List<Order>();
            }

            return _orders;
        }
    }

    //All the ICollection functions
}

订单

Order

public class Order
{
    [XmlElement("Id")]
    public int Id
    {
        get;
        set;
    }

    [XmlElement("Title")]
    public string Title
    {
        get;
        set;
    }

    [XmlElement("IsReserved")]
    public bool IsReserved
    {
        get;
        set;
    }

    [XmlElement("Count")]
    public int Count
    {
        get
        {
            return this.Products.Count;
        }
        set
        {

        }
    }

    // not serializing
    [XmlElement("Product")]
    public Product ProductTest
    {
        get
        {
            return new Product();
        }
    }

    // not serializing
    [XmlArray("Products")]
    public ICollection<Product> Products
    {
        get
        {
            return this._products;
        }

    }

    private List<Product> _products;

    public Order()
    {
        var rand = new Random();
        var count = rand.Next(1, 5);
        this._products = new List<Product>();

        for (int i = 0; i < count; i++)
        {
            this._products.Add(new Product());
        }
    }
}

产品

Product

[Serializable]
public class Product 
{
    [XmlElement("Id")]
    public int Id
    {
        get;
        set;
    }

    [XmlElement("Title")]
    public string Title
    {
        get;
        set;
    }

    public Product()
    {
        var rand = new Random();
        this.Id = rand.Next(100, 9999);
        this.Title = "Product " + this.Id;
    }
}

输出

Output

<?xml version="1.0"?>
<Orders xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <Order>
    <Id>619883</Id>
    <Title>Order 619883</Title>
    <IsReserved>false</IsReserved>
    <Count>3</Count>
  </Order>
  <Order>
    <Id>961448</Id>
    <Title>Order 961448</Title>
    <IsReserved>false</IsReserved>
    <Count>3</Count>
  </Order>
  <Order>
    <Id>483677</Id>
    <Title>Order 483677</Title>
    <IsReserved>false</IsReserved>
    <Count>2</Count>
  </Order>
  <Order>
    <Id>512026</Id>
    <Title>Order 512026</Title>
    <IsReserved>false</IsReserved>
    <Count>2</Count>
  </Order>
  <Order>
    <Id>916029</Id>
    <Title>Order 916029</Title>
    <IsReserved>false</IsReserved>
    <Count>4</Count>
  </Order>
  <Order>
    <Id>109800</Id>
    <Title>Order 109800</Title>
    <IsReserved>false</IsReserved>
    <Count>4</Count>
  </Order>
</Orders>

我完全莫名其妙。深刻的序列化似乎是工作，否则订单将不会得到OrderCollection内部系列化，但它只是停止。有什么建议？

I'm completely baffled. Deep serialization seems to be working because otherwise order wouldn't get serialized inside the OrderCollection, but then it just stops. Any advice?

推荐答案

您必须改变的ICollection到列表。 。接口没有可序列化

You have to change ICollection to List. An interface isn't serializeable.

[XmlArray("Products")]
public List<Product> Products
{
    get
    {
        return this._products;
    }

}

和ProductTest不起作用，因为缺少二传手

And ProductTest doesn't work because of the missing setter
