我目前遇到XSD问题。通常情况下,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>
但偶尔看起来会像这样:
<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>
为了尝试捕获多个Starts和Stops的潜力,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>
但是当我使用序列化为xsd.exe的xsd.exe将它转换为C#类时,它们都会生成一系列Starts,然后打印一个Stops数组:
<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>
这与XML文件不匹配。有谁知道怎么做这样的事情吗?非常感谢。
我提出了一个有效的解决方案,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>
答案 0 :(得分:1)
您只是错过了/order
参数。
尝试这样的事情:xsd / c / order your.xsd
凭借额外的订单价值,输出可与您拥有的产品区分开来:
[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;
}
}
像这样的简单测试程序可以正确地往返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);
}
}
}
}
