C#Xml Deserializion错误

我是新手.net和xamarin.我正在尝试开发一个xamarin表单应用程序.当我尝试反序列化我的xml时,我会收到错误.

Error Message is

[XmlRoot("REPORTLIST")]
[Serializable]
class REPORTLIST
{
    public REPORTLIST()
    {

    }       

    public List<ROW> ROW { get; set; }

}
[Serializable]
class ROW
{
    public ROW()
    {

    }
    public string INSTNUMBER { get; set; }
    public string MATERIAL { get; set; }

}

我的xml文件是

 <REPORTLIST>
     <ROW>
        <MATERIAL>A</MATERIAL>
        <INSTNUMBER>B</INSTNUMBER>
    </ROW>
 </REPORTLIST>

这是我的反序列化方法

    public static Stream GenerateStreamFromString(string s)
    {
        MemoryStream stream = new MemoryStream();
        StreamWriter writer = new StreamWriter(stream);
        writer.Write(s);
        writer.Flush();
        stream.Position = 0;
        return stream;
    }
    REPORTLIST Deserialize1(String MyXml)
    {
      XmlSerializer serializer = new XmlSerializer(typeof(REPORTLIST));
      return (REPORTLIST)serializer.Deserialize(GenerateStreamFromString(MyXml));

    }

序列化程序出现错误.反序列化

解决方法:

错误消息是：

REPORTLIST is inaccessible due to its protection level. Only public types can be processed.

将类型公之于众. XmlSerializer无法处理内部类型.另外：你不需要[Serializable] – XmlSerializer并不关心.

你还需要集合上的[XmlElement],告诉它不要添加/期望一个包装元素.

最终工作版本：

[XmlRoot("REPORTLIST")]
public class ReportList
{
    [XmlElement("ROW")]
    public List<Row> Rows { get; } = new List<Row>();    
}
public class Row
{
    [XmlElement("INSTNUMBER")]
    public string InstNumber { get; set; }
    [XmlElement("MATERIAL")]
    public string Material { get; set; }
}
