XmlNodeReader 返回 {None}

我目前在从 Web 服务调用反序列化 XmlDocument 时遇到问题，这是我的代码： -


 public void getTest(XmlDocument requestDoc)
    {
        XmlDocument results = new XmlDocument();
        XmlSerializer serial = new XmlSerializer(typeof(DataRequest));
        DataRequest req;
        XmlNodeReader reader = new XmlNodeReader(requestDoc.DocumentElement);
        req = (DataRequest)serial.Deserialize(reader);
        response.write(req.toString());
    }

现在，我遇到的问题是，当我单步执行调试时，XmlNodeReader 仅包含“{None}”，requestDoc 肯定有预期的 XML 结构，有什么想法吗？

亲切的问候吉布

I'm currently having trouble deserializing an XmlDocument from a web service call, here is my code : -


 public void getTest(XmlDocument requestDoc)
    {
        XmlDocument results = new XmlDocument();
        XmlSerializer serial = new XmlSerializer(typeof(DataRequest));
        DataRequest req;
        XmlNodeReader reader = new XmlNodeReader(requestDoc.DocumentElement);
        req = (DataRequest)serial.Deserialize(reader);
        response.write(req.toString());
    }

now, the trouble I am having is that the XmlNodeReader just contains "{None}" when I step through in debug, the requestDoc definatly has the expected XML structure, any ideas?

Kind regards
Gib

“none”可能只是意味着它还没有开始迭代，并且处于 BOF（因为缺乏更好的术语）。它应该仍然有效。通常，如果不是，则意味着命名空间不正确 - 仔细检查源代码中的 xmlns。

这工作得很好，例如：

public class Test
{
    static void Main()
    {
        var doc = new XmlDocument();
        doc.LoadXml(@"<Test foo=""bar""></Test>");
        var ser = new XmlSerializer(typeof(Test));
        using (var reader = new XmlNodeReader(doc.DocumentElement))
        {
            var test = (Test)ser.Deserialize(reader);
            Console.WriteLine(test.Foo);
        }

    }
    [XmlAttribute("foo")]
    public string Foo { get; set; }
}

The "none" probably just means it hasn't started iterating yet, and is at BOF (for want of a better term). It should still work. Usually, if it doesn't it means the namespaces are incorrect - double-check for xmlns in the source.

This works fine, for example:

public class Test
{
    static void Main()
    {
        var doc = new XmlDocument();
        doc.LoadXml(@"<Test foo=""bar""></Test>");
        var ser = new XmlSerializer(typeof(Test));
        using (var reader = new XmlNodeReader(doc.DocumentElement))
        {
            var test = (Test)ser.Deserialize(reader);
            Console.WriteLine(test.Foo);
        }

    }
    [XmlAttribute("foo")]
    public string Foo { get; set; }
}
