C# 使用System.xml.Serialization.XmlSerializer反序列化有效xml文件时存在差异
这是一个相当复杂的问题,请提前感谢。以下两个xml文件都根据给定的架构进行验证,但在尝试使用.Net的XmlSerializer进行反序列化时,只有第一个文件正确执行此操作:C# 使用System.xml.Serialization.XmlSerializer反序列化有效xml文件时存在差异,c#,xml,xml-serialization,xmlserializer,C#,Xml,Xml Serialization,Xmlserializer,这是一个相当复杂的问题,请提前感谢。以下两个xml文件都根据给定的架构进行验证,但在尝试使用.Net的XmlSerializer进行反序列化时,只有第一个文件正确执行此操作: <ex:iso_10303_28 xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.iai-tech.org/ifcXML/IFC2x3/

我的反序列化程序本质上是:
iso_10303_28 deserialized = (iso_10303_28)serializer.Deserialize( reader );
//using NUnit
Assert.IsNotNull(deserialized);
Assert.IsNotNull(deserialized.uos);
uos1 uos1 = deserialized.uos as uos1;
Assert.IsNotNull(uos1);
Assert.IsNotNull(uos1.Items); //<---FAILS HERE
Assert.AreEqual(3, uos1.Items.length);
以前有人遇到过这个问题吗?这有什么原因吗?我错过什么了吗?是否有修复或解决方法
由于模式和代码的其余部分相当大,并且试图将它们简化到最小失败部分会导致更多问题(请参阅),因此我没有将它们粘贴到这里。但是,如果需要,这个问题的模式、单元测试和源代码可以在中找到。在文件1中,两个XML文件不相同,uso在ex下是合格的,所以它在“urn:iso.org:standard:10303:part(28):version(2):xmlschema:common”命名空间下,而在第二个命名空间中它不是,并且在默认命名空间下 在类“iso_10303_28”中,uos类型的属性uos,这意味着XmlSerializer将在与类“uos”描述的iso_10303_28和“xsi:type”uos相同的命名空间下使用名为“uos”的元素(默认情况下),并在相同的“urn:iso.org:standard:10303:part(28):version(2):xmlschema:common”命名空间下使用。这就解释了为什么在第二个xml中会出现null。 如果您无法控制xml,并且应该能够对其中任何一个进行反序列化,请尝试以下操作
public enum uosChoice
{
[XmlEnum("http://www.iai-tech.org/ifcXML/IFC2x3/FINAL:uos")]

在应用#2时,我遇到了几个错误。[xmlcoiceIdentifier(“忽略”)]
应该是[xmlcoiceIdentifier(“uosChoice”)]
和公共uosChoice uosChoiceField
应该有[xmlcoliner()]
属性。按照上面的注释进行这些更改(作为第7版提交到code.google.com/p/ifc-dotnet/source/checkout),反序列化测试现在反序列化uos,因此它不是空的。不幸的是,它无法将uos强制转换为uos1,这意味着所有重要的uos1。项目仍然无法访问。:(抱歉,[xmlcoiceIdentifier(“忽略”)]应更改为[xmlcoiceIdentifier(“uosChoice”))]正如前面指出的那样,像这样更改XmlElement属性将正确解析为uos1[XmlElement(ElementName=“uos”,Namespace=”“,Type=typeof(uos1))],我已经编辑了这篇文章以反映-在XmlElement中添加类型-这对您有用
