使用带有多个类的类序列化为xml

我正在使用asp.net和c#来序列化一些使用类输入的数据。这个类是从一个xsd文件生成的。我使用这个类来生成一个xml文件。我正在努力理解如何引用所有这些类并将其序列化到一个xml文件。

这是我的类代码。它在我的项目中的一个单独的文件中:

 namespace Ce
{
    using System.Xml.Serialization;
// 
// This source code was auto-generated by xsd, Version=4.0.30319.33440.
// 

public partial class AddRequest
{
    private CDocument cDocumentField;
    /// <remarks/>
    [System.Xml.Serialization.XmlElementAttribute(Namespace = "x")]
    public CDocument CDocument
    {
        get
        {
            return this.cDocumentField;
        }
        set
        {
            this.cDocumentField = value;
        }
    }
}

public partial class CDocument
{
    private CaseA caseAField;
    /// <remarks/>
    [System.Xml.Serialization.XmlElementAttribute(Namespace = "x")]
    public CaseA CaseA
    {
        get
        {
            return this.caseAField;
        }
        set
        {
            this.caseAField = value;
        }
    }
}

public partial class CaseA
{
    public string dCTextField;
    private string dLField;

    /// <remarks/>
    [System.Xml.Serialization.XmlElementAttribute(Namespace = "x")]
    public string DCText
    {
        get
        {
            return this.dCTextField;
        }
        set
        {
            this.dCTextField = value;
        }
    }
    /// <remarks/>
    [System.Xml.Serialization.XmlElementAttribute(Namespace = "x")]
    public string DLU
    {
        get
        {
            return this.dLField;
        }
        set
        {
            this.dLField = value;
        }
    }
}
}

为了序列化，我在我的代码后面有一个按钮单击事件:

 protected void CaseSubmitButton_Click(object sender, EventArgs e)
    {
CaseA CSerialize = new CaseA();
    CSerialize.DCText = casetextboxt.text;
    CSerialize.DLu = "''app";
    XmlSerializer Serializer = new XmlSerializer(typeof(CaseA));
    StreamWriter Writer = new StreamWriter(Server.MapPath("~/XmlPackages/" + xmlPackageFilename));
    Serializer.Serialize(Writer, CSerialize);
    Serializer.Serialize(Writer, CSerialize); 
}

通过这个按钮点击事件，我得到这个xml格式:

<?xml version="1.0" encoding="utf-8"?>
<CaseA xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <DCText>'apptest</DCText>
    <DLU>'apptest</DLU>
</CaseA>

我想引用其他两个类来获得:

    <?xml version="1.0" encoding="utf-8"?>
<Addrequest>
 <Cdocument>
   <CaseA xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <DCText>'apptest</DCText>
    <DLU>'apptest</DLU>
   </CaseA>
  </Cdocument>
</Addrequest>

CaseA cSerialize = new CaseA();
cSerialize .DCText = casetextboxt.text;
cSerialize .DLu = "''app";
CDocument document = new CDocument();
document.CaseA = cSerialize ;
AddRequest root = new AddRequest();
root.CDocument = document;
XmlSerializer serializer = new XmlSerializer(typeof(AddRequest), new Type[] { typeof(CDocument), typeof(CaseA) });
StreamWriter writer = new StreamWriter(Server.MapPath("~/XmlPackages/" + xmlPackageFilename));
serializer.Serialize(writer, root);
