如何将异常对象序列化为xml字符串 [英] how to serialise exception object as xml string
本文介绍了如何将异常对象序列化为xml字符串的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我想是这样
try
{
//code here
}
catch (Exception ex)
{
stringXML = Exception.toXML();
}
让stringXML的价值将是
so that the value of stringXML would be
<exception><message></message><innerException></innerException></exception>
例如...
如何这可能吗?
推荐答案
这取决于你想要多少代码编写。一个简单的方法是写自己的对象,并使用的XmlSerializer
:
It depends how much code you want to write. One simple approach would be to write your own object and use XmlSerializer
:
[XmlRoot("exception"), XmLType("exception")]
public class SerializableException {
[XmlElement("message")]
public string Message {get;set;}
[XmlElement("innerException")]
public SerializableException InnerException {get;set;}
}
和映射只是一个普通的异常到此。但由于它是简单,无论如何,也许的XmlWriter
是不够好...
and just map a regular exception into this. But since it is simple anyway, maybe XmlWriter
is good enough...
public static string GetXmlString(this Exception exception)
{
if (exception == null) throw new ArgumentNullException("exception");
StringWriter sw = new StringWriter();
using (XmlWriter xw = XmlWriter.Create(sw))
{
WriteException(xw, "exception", exception);
}
return sw.ToString();
}
static void WriteException(XmlWriter writer, string name, Exception exception)
{
if (exception == null) return;
writer.WriteStartElement(name);
writer.WriteElementString("message", exception.Message);
writer.WriteElementString("source", exception.Source);
WriteException(writer, "innerException", exception.InnerException);
writer.WriteEndElement();
}
