我怎樣才能序列化使用ProductXmlSerializer的屬性和多個元素的
只有1個實例的Updates
UpdatesXmlSerializer
只有1實例可以包含多個Item以下結構
Item可以包含多個Artifact
XML：
<Product>
<Cycle Type = "x0446" />
<Brand Type = "z773g" Include="All" />
<Updates>
<Item Name = "Foo">
<Artifact Kind="6" Action="3" />
</Item>
<Item Name = "Bar">
<Artifact Kind="6" Action="3" />
<Artifact Kind="53" Action="3" />
</Item>
</Updates>
</Product>
這裏是一些代碼（一個屬性錯過了）
using System;
using System.Xml;
using System.Xml.Serialization;
using System.Collections.Generic;
[Serializable]
[XmlRoot("Product")]
public class Product
{
[XmlElement("Cycle")]
public Cycle Cycle { get; set; }
[XmlElement("Updates")]
public Updates Updates { get; set; }
public Product()
{
Cycle = new Cycle();
Updates = new Updates();
}
}
[Serializable]
public class Cycle
{
[XmlAttribute("Type")]
public string Type { get; set; }
}
[Serializable]
public class Updates
{
[XmlElement("Item")]
public List<Item> Items { get; set; }
public Updates()
{
Items = new List<Item>();
}
}
[Serializable]
public class Item
{
[XmlElement("Artifact", typeof(Artifact))]
public List<Artifact> Artifacts { get; set; }
public Item()
{
Artifacts = new List<Artifact>();
}
}
[Serializable]
public class Artifact
{
[XmlAttribute("Kind")]
public int Kind { get; set; }
}
這裏的序列化代碼
using System;
using System.Xml;
using System.Xml.Serialization;
using System.Collections.Generic;
using System.IO;
using System.Text;
private static string SerializeMe(object o)
{
XmlSerializer s = new XmlSerializer(o.GetType());
MemoryStream stream = new MemoryStream();
XmlWriter writer = new XmlTextWriter(stream, Encoding.Default);
s.Serialize(writer, o);
stream.Flush();
stream.Seek(0, SeekOrigin.Begin);
return Encoding.Default.GetString(stream.ToArray());
}
現在這裏一個控制檯上
static void Main(string[] args)
{
Product p = new Product();
p.Cycle.Type = "whatever";
Item i = new Item();
i.Artifacts.Add(new Artifact{Kind = 45});
p.Updates.Items.Add(i);
Console.WriteLine(SerializeMe(p));
Console.ReadLine();
}
希望測試代碼這有助於:)
你可以control xml serialization using attributes。使用XmlAttribute屬性，將默認序列化更改爲元素序列化爲屬性。使用XmlElement屬性將列表序列化爲xml元素的平面序列。
public class Product
{
public Cycle Cycle { get; set; }
public Brand Brand { get; set; }
public List<Item> Updates { get; set; }
}
public class Cycle
{
[XmlAttribute("Type")]
public string Type { get; set; }
}
public class Brand
{
[XmlAttribute("Type")]
public string Type { get; set; }
[XmlAttribute("Include")]
public string Include { get; set; }
}
public class Item
{
[XmlAttribute("Name")]
public string Name { get; set; }
[XmlElement("Artifact")]
public List<Artifact> Artifacts { get; set; }
}
public class Artifact
{
[XmlAttribute("Kind")]
public int Kind { get; set; }
[XmlAttribute("Action")]
public int Action { get; set; }
}
連載：
Product p = new Product()
{
Cycle = new Cycle() { Type = "x0446" },
Brand = new Brand() { Type = "z773g", Include = "All" },
Updates = new List<Item>()
{
new Item() { Name = "Foo",
Artifacts = new List<Artifact>() {
new Artifact() { Action = 3, Kind = 6 }
}
},
new Item() { Name = "Bar",
Artifacts = new List<Artifact>() {
new Artifact() { Action = 3, Kind = 6 },
new Artifact() { Action = 3, Kind = 53 },
}
}
}
};
XmlSerializer serializer = new XmlSerializer(typeof(Product));
Stream stream = new MemoryStream(); // use whatever you need
serializer.Serialize(stream, p);
結果：
<Product>
<Cycle Type = "x0446" />
<Brand Type = "z773g" Include="All" />
<Updates>
<Item Name = "Foo">
<Artifact Kind="6" Action="3" />
</Item>
<Item Name = "Bar">
<Artifact Kind="6" Action="3" />
<Artifact Kind="53" Action="3" />
</Item>
</Updates>
</Product>
您可以使用[XmlElement的]的陣列或列表屬性屬性和XmlSerializer的是足夠聰明的拿起那個，並列出它們在你的xml中一個接一個。
OR
您可以使用Visual Studio XML與班級發生器更復雜的結構： - 點擊開始菜單在Windows - 點擊 「所有程序」 - 找到的Microsoft Visual Studio文件夾，然後點擊 - 單擊Visual Studio工具文件夾 - 單擊開發人員命令提示符... - 假設您的xml保存在C：\ test \ Sample.xml中 - 鍵入「xsd C：\ test \ Sample.xml/out ：C：\ test「 這應該告訴你一個架構已經創建。 - 鍵入「xsd C：\ test \ Sample.xsd/c/out：C：\ test」 這應該會告訴您一個.cs類是爲您創建的，將其複製到您的解決方案中，可能會使用名稱空間更改對於它的xsd命令參數） - 創建的類可能會被命名爲奇怪，並且更難於使用，如果您有複雜的XML或模式，請使用此方法。 - 你可以用擴展部分類（看看它）生成的代碼，不修改生成的代碼直接
-
這裏的直接編碼（不產生）會是什麼樣子：
public class Product{
[XmlElement]
public Cycle Cycle {get;set;}
[XmlElement]
public Brand Brand {get;set;}
[XmlElement]
public Updates Updates {get;set;}
}
public class Updates{
[XmlElement("Item")]
public UpdateItem[] Items{get;set;}
}
public class UpdateItem{
[XmlAttribute]
public string Name{get;set;} // use [XmlAttribute] in Cycle, Brand and Artifact classes
[XmlElement("Artifact")]
public Artifact[] Artifact{get;set;}
}
//.... etc
，這裏是生成的代碼是什麼樣子：
/// <remarks/>
[System.CodeDom.Compiler.GeneratedCodeAttribute("xsd", "4.0.30319.17929")]
[System.SerializableAttribute()]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType=true)]
public partial class ProductUpdatesItem {
private ProductUpdatesItemArtifact[] artifactField;
private string nameField;
/// <remarks/>
[System.Xml.Serialization.XmlElementAttribute("Artifact", Form=System.Xml.Schema.XmlSchemaForm.Unqualified)]
public ProductUpdatesItemArtifact[] Artifact {
get {
return this.artifactField;
}
set {
this.artifactField = value;
}
}
[/代碼]
如果您有一個用於此結構的XML模式（或可以生成一個） - 我的首選是使用XSD.exe生成該類。
