我收到以下错误：

System.InvalidOperationException：“ XML文档中存在错误（33、14）。”

内部异常

InvalidOperationException：无法识别指定的类型：   名称='genericDrug'，名称空间='http://webservice.sirkb/'，位于http://www.govtalk.gov.uk/CM/envelope'>。

我从this线程中注意到，如果我从XML文件中删除xsi:type="ns2:genericDrug"，则可以反序列化XML。我无法修改XML，因为它是我对请求的响应。在XML上执行字符串替换不是一个好习惯，因此我正在寻找更好的解决方案。

这可能是来自this one的重复问题，但是由于我无法解决问题，因此我将其再次发布，因为很难在评论部分获得帮助。

基于上述问题，我试图更改public partial class returnDRUG的注释

来自

[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true, Namespace = "http://www.govtalk.gov.uk/CM/envelope")]

到

[System.Xml.Serialization.XmlTypeAttribute(Namespace = "http://www.w3.org/2001/XMLSchema-instance", TypeName = "genericDrug")]

但仍然无法解析XML。

解析代码很简单

var deserializer = new XmlSerializer(typeof(GovTalkMessage));
TextReader textReader = new StreamReader("drug.xml"); //saved response in file for simplicity
GovTalkMessage response;
response = (GovTalkMessage)deserializer.Deserialize(textReader);
textReader.Close();

如何对GovTalkMessage对象中的XML进行反序列化？

Answer 1

您需要更改returnDRUG类的修饰

从此

[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true, Namespace = "http://www.govtalk.gov.uk/CM/envelope")]
public partial class returnDRUG

对此

[System.Xml.Serialization.XmlTypeAttribute(TypeName = "genericDrug", Namespace = "http://webservice.sirkb/")]
public partial class returnDRUG

将其类型指定为“ genericDrug”，关键点是，将其名称空间更正为“ http://webservice.sirkb/”

我刚刚使用了您的代码，并使用此更改设法取消了序列化。

解释是，如果您看一下DRUG的定义，您会发现它的类型在名称空间别名“ ns2”中定义为“ genericDRUG”

<DRUG xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="ns2:genericDrug">

如果您查看ns2别名的定义，您会发现它是“ http://webservice.sirkb/”

<ns2:getGenericDrugsResponse xmlns:ns2="http://webservice.sirkb/">

一些附加功能可以防止 DRUG 对象的默认值

returnDrug类的每个属性都应具有名称空间http://www.govtalk.gov.uk/CM/envelope。

完整的类应具有以下形式：

[System.Xml.Serialization.XmlTypeAttribute(TypeName = "genericDrug", Namespace = "http://webservice.sirkb/")]
