C# XML序列化集合不'；不显示在XML中

我正在尝试序列化一个继承接口ICollection的类，正如在网站上看到的那样，但它并没有出现在我的XML中。可能出了什么问题？为什么我的XMLSerializer没有包含

AssertionAttribute

集合？至于我的例子，我为所附的大量代码提前道歉

为此元素生成的XML：

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

AssertionAttributes.cs-类应包含AssertionAttribute类型的集合

[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-应在xml中显示为多个标记（生成时）

AttributeValue.cs-一个XML值，用于存储此元素的文本值

[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，仅序列化对象的公共属性和字段。您的

AssertionAttribute

是一个公共字段，因此应该序列化它，对吗？实际上，否：请注意单词

object

：）。由于

AssertionAttribute

是

static

，因此它是类的字段，而不是类的对象的字段。如果您可以安排删除

static

修饰符之类的操作，那么应该可以做到这一点

[Serializable]

public class AssertionAttributes : ICollection
