c# - 同一张表 'tableName'不能是两个嵌套关系中的子表

转载作者：数据小太阳更新时间：2023-10-29 02:45:53

使用 XSD.EXE我生成了一个 *.cs 文件来序列化 XML。序列化时出现错误

“同一个表‘DefaultFont’不能是两个嵌套关系中的子表。”

为什么我会收到错误消息？我可以在不使用 XSLT 转换的情况下修复错误吗？

序列化代码

        StreamReader fs = new StreamReader(@"C:\path\DocumentSample.xml");
        XmlSerializer serializer = new XmlSerializer(typeof(PhysDocDocument));
        var result = serializer.Deserialize(fs) as PhysDocDocument;//exception thrown here

示例 XML

<PhysDocDocument xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <PhysDocNode HeaderVisible="true" Display="Summary" IsCollapsed="false" CopyForwardEnabled="true" IsHidden="false" Borders="false">

最佳答案

您生成的一些类在 XmlTypeAttribute 中设置了 AnonymousType=true。当我修改它并添加真实的类名时 - 错误消失了。这是完整的工作示例(请注意，我将“MemoPrompt”和“PromptPlugin”类名称添加到 XmlTypeAttribute):

using System.Xml.Serialization;
using System.IO;
using System;

class App
{
  static void Main()
  {
    StreamReader fs = new StreamReader(@"sample.xml");
    XmlSerializer serializer = new XmlSerializer(typeof(PhysDocDocument));
    var result = serializer.Deserialize(fs) as PhysDocDocument;  
    Console.WriteLine(result);
  }
}
