Deserialize XML string to Object Error : There is an Error in xml document (1,2)
提问by Saher Ahwal
From windows event viewer I can get the following xml structure:
从 Windows 事件查看器中，我可以获得以下 xml 结构：
<Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event">
<System>
<Provider Name="XXXXXXXXXX" Guid="{YYYYYYYY}" />
<EventID>XYZ</EventID>
<Version>0</Version>
<Level>L</Level>
<Task>A</Task>
<Opcode>0</Opcode>
<Keywords>0x000xyzh</Keywords>
<TimeCreated SystemTime="2012-06-28T15:44:04.997837000Z" />
<EventRecordID>153</EventRecordID>
<Correlation ActivityID="{DDDDDDDDD}" />
<Execution ProcessID="199999" ThreadID="90990" />
<Channel>Microsoft-Windows-ABCDEFG/Admin</Channel>

</System>
<EventData>
<Data Name="name1">data1</Data>
<Data Name="name2">data2</Data>
<Data Name="name3">data3</Data>

</Event>
I am only interested in the EventData section of the xml. I have created the following very simple classes:
我只对 xml 的 EventData 部分感兴趣。我创建了以下非常简单的类：
public class Event
{
public EventData EventData;
}
public class EventData
{
public String[] Data;
}
I then use the following code:
然后我使用以下代码：
XmlSerializer serializer = new XmlSerializer(typeof(Event));
StringReader reader = new StringReader(evtXml);
evt = (Event)serializer.Deserialize(reader);
but on the first line of code, I get the following error:
但是在第一行代码中，我收到以下错误：
There is an error in XML document (1, 2).
There is an error in XML document (1, 2).
This error is not informative to me. Is the problem that I don't have all the fields in the classes or do I need some other class (other than XmlSerializer) to get the data from. The way I would like the data under the EventData is by name and data value (e.g name1 with data1) ...etc
这个错误对我来说没有信息。问题是我没有类中的所有字段，还是我需要一些其他类（XmlSerializer 除外）来获取数据。我希望 EventData 下的数据的方式是按名称和数据值（例如 name1 和 data1）...等
Important EDIT: the xml I am getting is generated by the ToXML()method of the EventRecordclass
重要编辑：我得到的 xml 是由EventRecord类的ToXML()方法生成的
Thanks
谢谢

XmlSerializer serializer = new XmlSerializer(typeof(Event),
"http://schemas.microsoft.com/win/2004/08/events/event");
StringReader reader = new StringReader(evtXml);
var evt = (Event)serializer.Deserialize(reader);
public class Event
{
public Data[] EventData;
}
public class Data
{
[XmlAttribute]
public string Name;
[XmlText]
public string Value;
}

XmlSerializer often tells you what the matte is; add some error handling, specifically:
XmlSerializer 经常告诉你遮罩是什么；添加一些错误处理，特别是：
try {
// your code
} catch(Exception ex) {
while(ex != null) {
Console.WriteLine(ex.Message);
ex = ex.InnerException;
}
}
I'm guessingit is a namespace issue; try:
我猜这是一个命名空间问题；尝试：
[XmlRoot("Event",
Namespace="http://schemas.microsoft.com/win/2004/08/events/event")]
public class Event {...}
