Question

我正在尝试序列化一个继承了this网站上所见的接口ICollection的类，但是它没有出现在我的XML上。什么可能是错的？为什么我的XMLSerializer包括AssertionAttribute集合？至于我的例子，我提前为所附的大量编码道歉。

为此元素生成的XML：

    <saml:AttributeStatement xmlns:xs="http://www.w3.org/2001/XMLSchema" />

XML预计将从我的示例中生成：

<saml:AttributeStatement xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <saml:Attribute NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:basic" Name="Language">
    <saml:AttributeValue xsi:type="xs:string" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">en-US</saml:AttributeValue>
  </saml:Attribute>
  <saml:Attribute NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:basic" Name="fromApp">
    <saml:AttributeValue xsi:type="xs:string" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">SP2</saml:AttributeValue>
  </saml:Attribute>
  <saml:Attribute NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:basic" Name="Action">
    <saml:AttributeValue xsi:type="xs:string" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">VSREPORT</saml:AttributeValue>
  </saml:Attribute>
</saml:AttributeStatement>

代码：

AttributeStatement.cs

[Serializable]
[XmlType(Namespace="http://www.w3.org/2001/XMLSchema")]
public class AttributeStatement
{
    private static AssertionAttributes attributes = new AssertionAttributes();

    [XmlNamespaceDeclarations]
    public XmlSerializerNamespaces xmlns = new XmlSerializerNamespaces();

    [XmlAttribute(AttributeName = "Attribute")]
    public static AssertionAttributes attribute;

    public AttributeStatement()
    {
        xmlns.Add("xs", "http://www.w3.org/2001/XMLSchema");
        SetAttributes();
    }

    private static void SetAttributes()
    {
        var languageAttribute = new AssertionAttribute("en-US");
        languageAttribute.Name = "Name";
        attributes.Add(languageAttribute);

        var fromAppAttribute = new AssertionAttribute("SP2");
        fromAppAttribute.Name = "fromApp";
        attributes.Add(fromAppAttribute);

        var actionAttribute = new AssertionAttribute("VSREPORT");
        actionAttribute.Name = "Action";
        attributes.Add(actionAttribute);

        attribute = attributes;
    }
}

AssertionAttributes.cs - 该类应包含Type AssertionAttribute的集合

[Serializable]
[XmlType(Namespace = "urn:oasis:names:tc:SAML:2.0:assertion")]
public class AssertionAttributes : ICollection
{
    [XmlNamespaceDeclarations]
    public XmlSerializerNamespaces xmlns = new XmlSerializerNamespaces();

    public AssertionAttributes()
    {
        xmlns.Add("saml", "urn:oasis:names:tc:SAML:2.0:assertion");
    }

    private ArrayList empArray = new ArrayList();

    public AssertionAttribute this[int index]
    {
        get { return (AssertionAttribute)empArray[index]; }
    }

    void ICollection.CopyTo(Array array, int index)
    {
        empArray.CopyTo(array, index);
    }

    int ICollection.Count
    {
        get { return empArray.Count; }
    }

    bool ICollection.IsSynchronized
    {
        get { return false; }
    }

    object ICollection.SyncRoot
    {
        get { return this; }
    }

    IEnumerator IEnumerable.GetEnumerator()
    {
        return empArray.GetEnumerator();
    }

    public void Add(AssertionAttribute assertionAttribute)
    {
        empArray.Add(assertionAttribute);
    }
}

AssertionAttribute.cs - 应该在xml中显示为多个标签（生成）

[Serializable]
[XmlType(Namespace = "urn:oasis:names:tc:SAML:2.0:assertion")]
public class AssertionAttribute
{
    [XmlAttribute(AttributeName = "NameFormat")]
    public string NameFormat = "urn:oasis:names:tc:SAML:2.0:attrname-format:basic";

    [XmlElement(ElementName = "AttributeValue")]
    public AttributeValue attributeValue;

    [XmlNamespaceDeclarations]
    public XmlSerializerNamespaces xmlns = new XmlSerializerNamespaces();

    public AssertionAttribute(string attributeValueText)
    {
        xmlns.Add("saml", "urn:oasis:names:tc:SAML:2.0:assertion");
        AttributeValueText = attributeValueText; 
        attributeValue = new AttributeValue(attributeValueText);
    }

    private string name;

    [XmlAttribute(AttributeName = "Name")]
    public string Name
    {
        get { return name; }
        set { name = value; }
    }

    private static string attributeValueText;

    public static string AttributeValueText
    {
        get { return attributeValueText; }
        set { attributeValueText = value; }
    }

}

AttributeValue.cs - 仅用于存储此元素的文本值的XML值

[Serializable]
[XmlType(Namespace="urn:oasis:names:tc:SAML:2.0:assertion")]
public class AttributeValue
{
    [XmlNamespaceDeclarations]
    public XmlSerializerNamespaces xmlns = new XmlSerializerNamespaces();

    public AttributeValue(string attributeValueText)
    {
        xmlns.Add("saml", "urn.oasis:names:tc:SAML:2.0:assertion");
        Text = attributeValueText;
    }

    private string text;

    [XmlText]
    public string Text
    {
        get { return text; }
        set { text = value; }
    }

}

默认情况下，在XML序列化期间，只会序列化对象的公共属性和字段。您的AssertionAttribute是公共字段，因此应该序列化，对吧？实际上，不：注意单词object :)。由于AssertionAttribute是static，因此它是该类的字段，而不是该类的对象。如果您可以安排诸如删除static修饰符之类的内容，那么应该这样做。

XML Serialize Collections不会出现在XML中
