Question

我正在尝试使用xsd.exe工具创建的对象反序列化和xml文件。当我尝试运行示例应用程序时，我收到以下异常，InvalidOperationException - XML文档（1,1）中存在错误。我在这做错了什么？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main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;
        }
    }

Answer 1

您的代码对我来说非常好。如果您在XML中有这个，请从顶部删除“示例XML文件”。如果你没有那个，你可能会遇到一些问题，如不可见的字符或可能的编码冲突。在SO上查看此链接，例如：Deserialization error in XML document(1,1)

Answer 2

我将文件扩展名从.cs更改为.xml。我还在项目中创建了一些部分类，并在类中添加了一些XML装饰。使用xsd.exe自动生成的类中没有任何更改。我的主要班级

 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;
        }

新的部分课程：

 [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; }
    }
