C# 在XSD中表示一对重复的XML元素

我目前在使用XSD时遇到问题。通常，条目如下所示：

<Entry Num="4">
    <Info>
        <Name>Something</Name>
        <ID>1234</ID>
        <Start>2013-01-07</Start>
        <Stop>2013-01-09</Stop>
        <Completed>6</Completed>
    </Info>
</Entry>

<Entry Num="5">
    <Info>
        <Name>SomethingElse</Name>
        <ID>5678</ID>
        <Start>2013-01-08</Start>
        <Stop>2013-01-10</Stop>
        <Start>2013-01-11</Start>
        <Stop>2013-01-12</Stop>
        <Completed>14</Completed>
    </Info>
</Entry>

某物
1234
2013-01-07
2013-01-09
6.

但有时会像这样：

<Entry Num="4">
    <Info>
        <Name>Something</Name>
        <ID>1234</ID>
        <Start>2013-01-07</Start>
        <Stop>2013-01-09</Stop>
        <Completed>6</Completed>
    </Info>
</Entry>

<Entry Num="5">
    <Info>
        <Name>SomethingElse</Name>
        <ID>5678</ID>
        <Start>2013-01-08</Start>
        <Stop>2013-01-10</Stop>
        <Start>2013-01-11</Start>
        <Stop>2013-01-12</Stop>
        <Completed>14</Completed>
    </Info>
</Entry>

某物
5678
2013-01-08
2013-01-10
2013-01-11
2013-01-12
14

为了尝试捕捉多次启动和停止的可能性，我尝试了以下方法：

<xs:sequence maxOccurs="unbounded">
    <xs:element name="Start" type="xs:dateTime" maxOccurs="1"/>
    <xs:element name="Stop" type="xs:dateTime" maxOccurs="1"/>
</xs:sequence>

<xs:sequence maxOccurs="unbounded">
    <xs:element name="Start" type="xs:dateTime" />
    <xs:element name="Stop" type="xs:dateTime" />
</xs:sequence>

<xs:sequence maxOccurs="unbounded">
    <xs:sequence>
        <xs:element name="Start" type="xs:dateTime" />
        <xs:element name="Stop" type="xs:dateTime" />
    </xs:sequence>
</xs:sequence>

<xs:sequence maxOccurs="unbounded">
    <xs:sequence>
        <xs:element name="Start" type="xs:dateTime" maxOccurs="1"/>
        <xs:element name="Stop" type="xs:dateTime" maxOccurs="1"/>
    </xs:sequence>
</xs:sequence>

但当我使用xsd.exe将其转换为C#类时，它们都会生成一个开始数组，然后打印一个停止数组，该类序列化为：

<Entry Num="5">
    <Info>
        <Name>SomethingElse</Name>
        <ID>5678</ID>
        <Start>2013-01-08</Start>
        <Start>2013-01-11</Start>
        <Stop>2013-01-10</Stop>
        <Stop>2013-01-12</Stop>
        <Completed>14</Completed>
    </Info>
</Entry>

某物
5678
2013-01-08
2013-01-11
2013-01-10
2013-01-12
14

这与XML文件不匹配。有人知道如何正确地做这样的事情吗？非常感谢

我提出了一个可行的解决方案，但并不理想

当前解决方案：

<xs:choice minOccurs="2" maxOccurs="unbounded">
    <xs:element name="Start" type="xs:dateTime"/>
    <xs:element name="Stop" type="xs:dateTime"/>
</xs:choice>

您只是错过了

/order

参数

尝试以下操作：xsd/c/order your.xsd

通过附加的顺序值，输出将与您拥有的不同：

[System.Xml.Serialization.XmlElementAttribute("Start", typeof(System.DateTime), DataType="date", Order=2)]
[System.Xml.Serialization.XmlElementAttribute("Stop", typeof(System.DateTime), DataType="date", Order=2)]
[System.Xml.Serialization.XmlChoiceIdentifierAttribute("ItemsElementName")]
public System.DateTime[] Items {
    get {
        return this.itemsField;
    }
    set {
        this.itemsField = value;
    }
}

这样一个简单的测试程序可以正确地往返于XML：

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

namespace ConsoleApplication2
{
    class Program
    {
        static void Main(string[] args)
        {
            XmlSerializer ser = new XmlSerializer(typeof(Entry));
            Entry o;
            using (Stream s = File.OpenRead(@"D:\...\representing-a-repeated-pair-of-xml-elements-in-xsd-2.xml"))
            {
                o = (Entry)ser.Deserialize(s);
            }
            using (Stream s = File.OpenWrite(@"D:\...\representing-a-repeated-pair-of-xml-elements-in-xsd-3.xml"))
            {
                ser.Serialize(s, o);
            }
        }
    }
}
