Xml序列化-创建对象层次结构来实现预定义的Xml结构
本文关键字：Xml 预定义 结构 实现 层次结构 序列化 创建对象 | 更新日期: 2023-09-27 18:06:27
我需要创建以下XML，并希望通过XmlSerialization创建它，以便可以通过对象动态生成数据本身。
<chart>
<series>
<value xid="0">Not Submitted: 20</value>
<value xid="1">Submitted: 11</value>
<value xid="2">Rejected: 2</value>
</series>
<graphs>
<graph gid="0">
<value xid="0" color="#FF0000">20</value>
<value xid="1" color="#00FF00">11</value>
<value xid="2" color="#0000FF">2</value>
</graph>
<graph gid="1">
<value xid="0" color="#FF0000">24</value>
<value xid="1" color="#00FF00">7</value>
<value xid="2" color="#0000FF">4</value>
</graph>
</graphs>
</chart>
我最初想到了这个，但它并不完全工作(事实上，其中一些是完全错误的)。什么好主意吗?
// the //chart/series/value elements with attributes
internal class BarChartSeriesValue
{
[XmlAttribute(AttributeName = "xid")]
public int Xid { get; set; }
[XmlText]
public int Value { get; set; }
}
// the //chart/graphs/graph/value elements with attributes
internal class BarChartGraphValue
{
[XmlAttribute(AttributeName = "xid")]
public int Xid { get; set; }
[XmlAttribute(AttributeName = "color")]
public string Color { get; set; }
[XmlText]
public int Value { get; set; }
}
// the //chart/series collection of values
internal class BarChartSeries : List<BarChartSeriesValue>
{
[XmlElement(ElementName = "series")]
public List<BarChartSeriesValue> Series { get; set; }
}
// the //chart/graphs/graph collection of values
internal class BarChartGraph : List<BarChartGraphValue>
{
[XmlAttribute(AttributeName = "gid")]
public int GraphId { get; set; }
}
// the //chart/graphs collection of graph elements
internal class BarChartData
{
[XmlElement(ElementName = "series")]
public BarChartSeries Series { get; set; }
[XmlElement(ElementName = "graphs")]
public BarChartGraph Graphs { get; set; }
}
EDIT - 8/22 11:24pm
当我说它完全错误时，我所要做的就是查看它并意识到数据结构不会映射到所需的XML。真正让我困惑的是嵌套图结构。
我以前不知道如何通过XSD从XML生成类。它看起来非常有用。
感谢所有提供解决方案的人
这是一个快速项目。
我使用这个类或它的一个变体:c#通用XML序列化类和XML序列化使用示例
这是你需要的代码。
[XmlRoot("chart")]
public class Chart
{
[XmlElement("series")]
public Series Series { get; set; }
[XmlArray("graphs")]
[XmlArrayItem("graph")]
public Graphs Graphs { get; set; }
}
public class Series
{
[XmlElement("value")]
public List<SeriesValue> Values { get; set; }
}
public class Graphs : List<Graph>
{
}
public class Graph
{
[XmlAttribute("gid")]
public int Gid { get; set; }
[XmlElement("value")]
public List<GraphValue> Values { get; set; }
}
public class GraphValue
{
[XmlAttribute("xid")]
public int Xid { get; set; }
[XmlAttribute("color")]
public String Color { get; set; }
[XmlText]
public int Value { get; set; }
}
public class SeriesValue
{
[XmlAttribute("xid")]
public int Xid { get; set; }
[XmlText]
public String Text { get; set; }
}
如何使用
class Program
{
static void Main(string[] args)
{
Chart c = new Chart();
c.Series = new Series();
c.Series.Values = new List<SeriesValue>();
c.Series.Values.Add(new SeriesValue() { Xid = 0, Text = "Not Submitted: 20" });
c.Series.Values.Add(new SeriesValue() { Xid = 1, Text = "Submitted: 11" });
c.Series.Values.Add(new SeriesValue() { Xid = 2, Text = "Rejected: 2" });
c.Graphs = new Graphs();
c.Graphs.Add(new Graph() { Gid = 0 });
c.Graphs[0].Values = new List<GraphValue>();
c.Graphs[0].Values.Add(new GraphValue() { Xid = 0, Color = "#FF0000", Value = 20 });
c.Graphs[0].Values.Add(new GraphValue() { Xid = 1, Color = "#00FF00", Value = 11 });
c.Graphs[0].Values.Add(new GraphValue() { Xid = 2, Color = "#0000FF", Value = 2 });
c.Graphs.Add(new Graph() { Gid = 1 });
c.Graphs[1].Values = new List<GraphValue>();
c.Graphs[1].Values.Add(new GraphValue() { Xid = 0, Color = "#FF0000", Value = 24 });
c.Graphs[1].Values.Add(new GraphValue() { Xid = 1, Color = "#00FF00", Value = 7 });
c.Graphs[1].Values.Add(new GraphValue() { Xid = 2, Color = "#0000FF", Value = 4 });
// Make sure it is Serializable
Serializer.SerializeToXML<Chart>(c, "chart.xml");
// Make sure it is Deserializable
Chart c2 = Serializer.DeserializeFromXML<Chart>("chart.xml");
}
}
您可以使用XSD.exe(我认为)作为visual studio的一部分来生成类。
如果你打开Visual Studio命令提示符，你可以访问它。
-
在硬盘上创建一个物理XML文件。(我使用您的xml和创建的sample.xml)
-
打开Visual Studio命令提示符
-
导航到目录
-
键入'xsd sample.xml'(不带引号)，这将生成sample.xsd
-
输入xsd样本。这将生成sample.cs
设置使用Microsoft Visual Studio 2008 x86工具的环境。
