XML反序列化失败 [英] XML deserialization fail

问题描述

我反序列化下面的XML文件。使用XML序列化与VSTS 2008 + C＃+。NET 3.5的。

I am deserializing the following XML file. Using XML serializer with VSTS 2008 + C# + .Net 3.5.

下面是XML文件。

<?xml version="1.0" encoding="utf-8"?>
<Person><Name>=b?olu</Name></Person>

下面是屏幕快照的XML文件的XML文件和二进制格式，

Here is the screen snapshot for the display of the XML file and binary format of the XML file,

如果有一些解决办法接受这样的角色，这将是伟大的！由于我的XML文件是很大的，如果这样的角色真的是无效的，应该被过滤，我想保持反序列化后剩余的XML文件的内容。

If there are some solutions to accept such characters, it will be great! Since my XML file is big, and if such characters are really invalid and should be filtered, I want to keep remaining content of XML file after deserialization.

目前XML序列化失败，出现InvalidOperationException和整个XML文件的信息将会丢失。

Currently XML deserialization fails with InvalidOperationException and the whole XML file information will be lost.

其实，开的时候在VSTS这个XML文件中，有错误是这样，错误1字符'？'，十六进制值0xFFFF在XML文档中是非法的。我很困惑，因为以二进制形式，没有0xFFFF的值。

Actually, when open this XML file in VSTS, there is error like this, Error 1 Character '?', hexadecimal value 0xffff is illegal in XML documents. I am confused since in the binary form, there is no 0xffff values.

任何解决方案或想法？

EDIT1：这里是我的code，用来反序列化XML文件，

here is my code which is used to deserialize XML file,

    static void Foo()
    {
        XmlSerializer s = new XmlSerializer(typeof(Person));
        StreamReader file = new StreamReader("bug.xml");
        s.Deserialize(file);
    }

public class Person
{
    public string Name;
}

推荐答案

您是否尝试过DataContractSerializer的呢？我遇到了一个有趣的情况，当有人复制并粘贴一些word或excel的东西到我的web应用程序：字符串包含了一些无效的控制字符（如垂直选项卡）。令我吃惊的把它发送到一个WCF服务，甚至要求当它读回100％原装时，这是序列化。纯.NET环境没有这个问题，所以我假设的DataContractSerializer能处理这些东西（这是恕我直言违反XML规范的，不过）。

解决方案

我们有访问同一个服务的另一个Java客户端 - 接收到这个纪录，当它失败...

Have you tried the DataContractSerializer instead? I've encountered an interesting situation, when someone copy and pasted some word or excel stuff into my web application: the string contained some invalid control characters (such as vertical tab). To my surprise this was serialized when sending it to a WCF service and even read back 100% original when requesting it. The pure .net environment did not have a problem with this, so I assume that the DataContractSerializer can handle such stuff (which is IMHO a violation of XML spec, however).

[之后我的评论丑陋的格式编辑下面]

We had another Java client accessing the same service - it failed when receiving this record...

试试这个：

Try this: 

第二个马克的意见是关于DataContractSerializers习惯，使XmlElements而不是XMLATTRIBUTES：

DataContractSerializer serializer = new DataContractSerializer(typeof(MyType)); using (XmlWriter xmlWriter = new XmlTextWriter(filePath, Encoding.UTF8)) { serializer.WriteObject(xmlWriter, instanceOfMyType); } using (XmlReader xmlReader = new XmlTextReader(filePath)) { MyType = serializer.ReadObject(xmlReader) as MyType; }

The comment of the second Marc is about DataContractSerializers habit to make XmlElements instead of XmlAttributes:

而不是

<AnElement AnAttribute="value" />
