反序列化XML无效操作异常
本文关键字：异常 操作 无效 XML 反序列化 | 更新日期: 2023-09-27 18:20:21
我正在尝试使用使用xsd.exe工具创建的对象来反序列化和xml文件。当我尝试运行示例应用程序时，我得到了以下异常，InvalidOperationException-XML文档（1，1）中存在错误。我在这里做错了什么？这是我的代码：
示例XML文件
<?xml version="1.0" encoding="utf-8"?>
<patient>
<pr>
<fname>Cindy </fname>
<lname>Knapp </lname>
<id>1 </id>
</pr>
<pr>
<fname>Regie </fname>
<lname>Miller </lname>
<id>2 </id>
</pr>
<ad>
<id>1</id>
<streetnumber>1200 NW</streetnumber>
<city>Miami </city>
<state>FL</state>
<zip>34488</zip>
</ad>
<ad>
<id>2</id>
<streetnumber>1299 NE</streetnumber>
<city>NY </city>
<state>NY</state>
<zip>9032</zip>
</ad>
</patient>
这是生成的类

在主函数中，我尝试反序列化xml文件。
class Program
{
static void Main(string[] args)
{
patient pr = new patient();
XmlSerializer serializer = new XmlSerializer(typeof(patient));
FileStream myStream = new FileStream(@"C:'com'dss'VXReports'XSD Document'EXAMPLE.CS", FileMode.Open);
pr = (patient)serializer.Deserialize(myStream);
string kr = string.Empty;
}
}

您的代码对我来说非常好。如果您的XML中有"示例XML文件"，请从顶部删除。如果你没有，你可能会遇到一些问题，比如看不见的字符，或者可能是编码冲突。请参阅SO上的此链接，例如：XML文档（1,1）中的反序列化错误
我将文件扩展名从in从.cs更改为.xml。我还在项目中创建了一些分部类，并为这些类添加了一些xml装饰。使用xsd.exe自动生成的类中没有任何更改。我的主类
static void Main(string[] args)
{
patient pr = new patient();
XmlSerializer serializer = new XmlSerializer(typeof(patient));
FileStream myStream = new FileStream(@"C:'com'dss'VXReports'XSD Document'EXAMPLE.XML", FileMode.Open);
pr = (patient)serializer.Deserialize(myStream);
string kr = string.Empty;
}
新的分部类：
[Serializable, XmlRoot("patient")]
public partial class patient
{
[XmlElement("pr")]
public patientPR[] pr { get; set; }
[XmlElement("ad")]
public patientAD[] ad { get; set; }
}
[Serializable, XmlType("pr")]
public partial class patientPR
{
[XmlElement("fname")]
public string fname { get; set; }
[XmlElement("lname")]
public string lname { get; set; }
[XmlElement("id")]
public int id { get; set; }
}
[Serializable, XmlType("ad")]
public partial class patientAD
{
[XmlElement("id")]
public int id { get; set; }
[XmlElement("streetnumber")]
public string streetnumber { get; set; }
[XmlElement("city")]
public string city { get; set; }
[XmlElement("state")]
public string state { get; set; }
[XmlElement("zip")]
public ushort zip { get; set; }
}
