在 C# 中，如何序列化 System.Exception?(.Net CF 2.0) [英] In C#, how can I serialize System.Exception? (.Net CF 2.0)

问题描述

我想将异常写入 MS 消息队列.当我尝试它时，我得到了一个例外.所以我尝试使用 XmlSerializer 来简化它，但它仍然引发异常，但它给了我更多信息:

I want to write an Exception to an MS Message Queue. When I attempt it I get an exception. So I tried simplifying it by using the XmlSerializer which still raises an exception, but it gave me a bit more info:

{"有一个错误反映类型'System.Exception'."}

{"There was an error reflecting type 'System.Exception'."}

带有内部异常:

{"无法序列化成员System.Exception.Data 类型System.Collections.IDictionary,因为它实现了 IDictionary."}

{"Cannot serialize member System.Exception.Data of type System.Collections.IDictionary, because it implements IDictionary."}

示例代码:

        Exception e = new Exception("Hello, world!");
        MemoryStream stream = new MemoryStream();
        XmlSerializer x = new XmlSerializer(e.GetType()); // Exception raised on this line

        x.Serialize(stream, e);
        stream.Close();

我试图保持这个尽可能简单，但我可能做得过头了.我想要整个位、堆栈跟踪、消息、自定义异常类型和自定义异常属性.我什至可能想再次抛出异常.

I tried to keep this a simple as possible, but I may have overdone it. I want the whole bit, stack trace, message, custom exception type, and custom exception properties. I may even want to throw the exception again.

推荐答案

我认为你基本上有两个选择:

I think you basically have two options:

1. 自己手动序列化(可能不想这样做).由于您在内部异常中获得的确切消息，XML 序列化肯定无法工作.
2. 创建您自己的自定义(可序列化)异常类，将抛出的异常中的数据注入您的自定义异常类中并对其进行序列化.
