同一个表'tableName'不能是两个嵌套关系中的子表

Posted 2023-04-12

技术标签:

【中文标题】同一个表\'tableName\'不能是两个嵌套关系中的子表【英文标题】：The same table 'tableName' cannot be the child table in two nested relations同一个表'tableName'不能是两个嵌套关系中的子表 【发布时间】：2012-11-02 01:32:46 【问题描述】：

使用 XSD.EXE 我生成了一个 *.cs 文件来序列化 XML。当我序列化时，我得到了错误

"The same table 'DefaultFont' cannot be the child table in two nested relations."

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">
        <LinkedPluginId>00000000-0000-0000-0000-000000000000</LinkedPluginId>
        <Plugin xsi:type="PromptPlugin" ID="2446441e-6eb2-49ef-b8e3-28f638755b75">
            <CopyForwardChecked>true</CopyForwardChecked>
            <PromptBase xsi:type="MemoPrompt">
                <Label>Comment</Label>
                <DocumentValue>
                    <Paragraphs />
                    <DefaultFont FontFamily="Arial" SizeInPoints="10" Style="Regular" />
                </DocumentValue>
                <ShowLabel>false</ShowLabel>
                <RenderHeader>false</RenderHeader>
            </PromptBase>
        </Plugin>

【问题讨论】：

【参考方案1】：

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，我在 XmlTypeAttribute 中添加了“MemoPrompt”和“PromptPlugin”类名）：

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);
