[ C# ] WPFでXML出力

WPFでXML出力をする必要があったので。

classをシリアライズでXML化

１．適当なクラスを作成

public class Person
{
    public string name { get; set; }
    public int age { get; set; }
}

public class Office
{
    public string name;
    public ObservableCollection<Person> persons;
}

適当に初期化する

private Office office;
private void init()
{
    office = new Office();
    office.name = "オフィス";
    office.persons = new ObservableCollection<Person>();
    office.persons.Add(new Person { name = "001", age = 11 });
    office.persons.Add(new Person { name = "002", age = 22 });
    office.persons.Add(new Person { name = "003", age = 33 });
}

※ ObservableCollectionを使っているのはXAML用に

２．XML出力

XmlSerializer serializer = new XmlSerializer(office.GetType());
using (FileStream fs = new FileStream(Directory.GetCurrentDirectory() + "\\" + "office.xml", FileMode.Create))
    serializer.Serialize(fs, office);

出力内容

<?xml version="1.0"?>
<Office xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <name>オフィス</name>
    <persons>
        <Person>
            <name>001</name>
            <age>11</age>
        </Person>
        <Person>
            <name>002</name>
            <age>22</age>
        </Person>
        <Person>
            <name>003</name>
            <age>33</age>
        </Person>
    </persons>
</Office>

３．XML読込

XmlSerializer serializer = new XmlSerializer(office.GetType());
using (FileStream fs = new FileStream(Directory.GetCurrentDirectory() + "\\" + "office.xml", FileMode.Open))
    office = (Office)serializer.Deserialize(fs);

これで取り込める

４．出力するタグ名を変更など

public class Person
{
    public string name { get; set; }
    [System.Xml.Serialization.XmlIgnoreAttribute]
    public int age { get; set; }
}

・System.Xml.Serialization.XmlIgnoreAttribute　XML出力しない

[System.Xml.Serialization.XmlRoot("root")]
public class Office
{
    public string name;
    [System.Xml.Serialization.XmlElement("members")]
    public ObservableCollection<Person> persons;
}

・System.Xml.Serialization.XmlRoot　ルート名変更

・System.Xml.Serialization.XmlElement　タグ名変更

上記を適用して出力すると、

<?xml version="1.0"?>
<root xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <name>オフィス</name>
    <members>
        <name>001</name>
    </members>
    <members>
        <name>002</name>
    </members>
    <members>
        <name>003</name>
    </members>
</root>
