如何将 XML 文件反序列化为对象列表

Question

我需要帮助，我有一个 XML 文件，我已经在一个名为 Class 1 的 class 上进行了序列化，其中包含另一个名为 class 类型的列表27=] 将列表序列化为 XML 文件后，我正在尝试将文件反序列化为服务类型列表

这是 class 1 个代码：

public class Class1

{
    public Class1()
    {
        ServiceList = new List<service>();

    }
    public List<service> ServiceList { get; set; }
}

public class service
{
    public string ServiceName { get; set; }
    public string Symbol { get; set; }

}

这是我的序列化代码：

 var filestream = new FileStream("sth.xml", FileMode.Create);
        new XmlSerializer(typeof(Class1)).Serialize(filestream,c);
        filestream.Close();

这是 XML 数据：

<?xml version="1.0"?>
<Class1 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<ServiceList>
<service>
  <ServiceName>cool</ServiceName>
  <Symbol>v</Symbol>
</service>
<service>
  <ServiceName>cool</ServiceName>
  <Symbol>v</Symbol>
</service>
<service>
  <ServiceName>cool</ServiceName>
  <Symbol>v</Symbol>
</service>
<service>
  <ServiceName>cool</ServiceName>
  <Symbol>v</Symbol>
</service>
<service>
  <ServiceName>cool</ServiceName>
  <Symbol>v</Symbol>
</service>
<service>
  <ServiceName>cool</ServiceName>
  <Symbol>v</Symbol>
</service>
<service>
  <ServiceName>cool</ServiceName>
  <Symbol>v</Symbol>
</service>
<service>
  <ServiceName>cool</ServiceName>
  <Symbol>v</Symbol>
</service>
<service>
  <ServiceName>cool</ServiceName>
  <Symbol>v</Symbol>
</service>
<service>
  <ServiceName>cool</ServiceName>
  <Symbol>v</Symbol>
</service>
 </ServiceList>
</Class1>

这是我的反序列化代码，运行正确但没有给我正确的输出

        XmlSerializer myDeserilizer = new XmlSerializer(typeof(List<service>) ,  new XmlRootAttribute("Class1"));
        FileStream myfilestream = new FileStream("sth.xml", FileMode.Open);
        var loadedData = (List<service>)myDeserilizer.Deserialize(myfilestream);
        myfilestream.Close();

问题是反序列化后我没有得到列表有帮助吗？？

Answer 1

按如下方式重写代码并查看结果：

[XmlRoot(ElementName = "Class1"), XmlType("Class1")]
public class Class1
{
  public Class1()
  {
     ServiceList = new List<service>();

  }
  [XmlElement(ElementName = "ServiceList")
  public List<service> ServiceList { get; set; }
}

[XmlRoot(ElementName = "Service"), XmlType("Service")]
public class service
{
   [XmlElement(ElementName = "ServiceName")
   public string ServiceName { get; set; }

   [XmlElement(ElementName = "Symbol")
   public string Symbol { get; set; }
}

然后按如下方式更改反序列化代码：

XmlSerializer myDeserilizer = new XmlSerializer(typeof(Class1));
FileStream myfilestream = new FileStream("sth.xml", FileMode.Open);
var loadedData = myDeserilizer.Deserialize(myfilestream);
myfilestream.Close();

应该可以，我在本地测试过

你过去的反序列化有问题，你可以简单地改变你的反序列化部分，如下所示。

        XmlSerializer myDeserilizer = new XmlSerializer(typeof(Class1));
        FileStream myfilestream = new FileStream("sth.xml", FileMode.Open);
        var loadedData = (Class1)myDeserilizer.Deserialize(myfilestream);
        var listOfServices = loadedData.ServiceList;
        myfilestream.Close();
