深入XML序列化中的C＃for循环

问题描述

我正在尝试制作一个深层嵌套的XML文件，在其中我想从另一个文件插入一些数据。

现在的样子：

  <Documents Count="1">
    <Item DATE="2020-09-01" CREATEDBY="TestUser">
      <Row ITEMID="" ACTIVE="" />
    </Item>
  </Documents>

我希望它看起来像这样：

  <Documents Count="1">
    <Item DATE="2020-09-01" CREATEDBY="TestUser">
      <Row ITEMID="" ACTIVE="" />
      <Row ITEMID="" ACTIVE="" />
      <Row ITEMID="" ACTIVE="" />
      <Row ITEMID="" ACTIVE="" />
    </Item>
  </Documents>

问题是节点“ Item”内部必须有很多行（节点“ Row”），我想通过读取每一行来填充另一个文件中的数据，并执行我需要的操作 for 循环。 我被困住了，因为它不允许我在其中添加 for 循环，是否有办法以某种方式在其中插入for循环？

谢谢。

这是我到目前为止编写的代码：

class Program
{
    static void Main(string[] args)
    {
        var xmlData = new XmlData();

        xmlData.documents.documentsItem.Add(new DocumentsItem()
        {
            DATE = DateTime.Now.ToString("yyyy-MM-dd"),CREATEDBY = "TestUser",documentsRow = new List<DocumentsRow>()
            {
            //<-- I want to insert a 'for' loop in here,but it won't allow me to do that
                new DocumentsRow()
                {
                    ITEMID = "",ACTIVE = "",}
            }
            });
        xmlData.documents.Count = xmlData.documents.documentsItem.Count;

        using (StreamWriter sw = new StreamWriter(@"c:\a\test.xml",false,Encoding.UTF8))
        {
            new XmlSerializer(typeof(XmlData)).Serialize(sw,xmlData);
        }

    }
}


public class XmlData
{
    [XmlElement("Documents")]
    public Documents documents = new Documents();

    [XmlIgnore]
    public DocumentsRow documentsRow = new DocumentsRow();
}


public class Documents
{
    public Documents()
    {
        documentsItem = new List<DocumentsItem>();
    }

    [XmlAttribute]
    public int Count { get; set; }

    [XmlElement("Item")]
    public List<DocumentsItem> documentsItem { get; set; }
}

public class DocumentsItem
{
    public DocumentsItem()
    {
        documentsRow = new List<DocumentsRow>();
    }

    [XmlAttribute]
    public string DATE { get; set; }

    [XmlAttribute]
    public string CREATEDBY { get; set; }

    [XmlElement("Row")]
    public List<DocumentsRow> documentsRow { get; set; }
}

public class DocumentsRow
{
    [XmlAttribute]
    public string ITEMID { get; set; }

    [XmlAttribute]
    public string ACTIVE { get; set; }
}
