C# 如何构造此XML的类？

如何将这个XML反序列化到C#中的类中

---

我在这些课上都学到了。请非常小心，因为某些更改区分大小写

用

private void frmXmlDeserialize_Load(object sender, EventArgs e)
{
    try
    {
        XmlSerializer xs = new XmlSerializer(typeof(Root));
        StreamReader sr = new StreamReader("import.xml");
        Root r = (Root)xs.Deserialize(sr);
        sr.Close();
    }
    catch (Exception ex)
    {
        Debug.WriteLine(ex.Message);
    }           
}

? 请发布您当前的代码，并解释哪些代码不起作用，以及您遇到的问题。请看一看-您可以使用它从XML生成一个XSD文件（尽管如果所做的假设不正确，您可能希望查看并更正它），然后在生成的XSD上再次运行它以生成一个C类。“它不起作用”这是对问题的拙劣描述。你能更具体地说明什么不起作用吗？例外情况？错误？预期的行为和实际的行为是什么？我说的是。这些是您需要了解的关于XML（和HTML）的基本知识。您有太多的

XmlRoot

s-XML文件只有一个根（在您的例子中是

root

元素）。
