Xml 序列化 - 创建对象层次结构以实现预定义的 xml 结构

Question

我需要创建以下 XML，并希望通过 XmlSerialization 创建它，以便数据本身可以通过对象动态生成。

<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>

我最初想出了这个，但它并不完全有效（事实上，其中一些完全是错误的）。有什么想法吗？

// 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; }
}

当我说这完全是错误的时，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。真正让我困惑的部分是嵌套图结构。
我以前不知道如何通过 XSD 从 XML 生成类。它看起来非常有用和有帮助。
感谢所有提供解决方案的人

这是一个快速项目。

我使用这个类或其变体：
C# 的通用 XML 序列化器类和 XML 序列化使用示例

下面是您需要的代码。

[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; }
}

以下是如何使用它。

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 生成该类，（我认为）它是 Visual Studio 的一部分。

如果您打开 Visual Studio 命令提示符，则可以访问它。

1. 在硬盘上的某个位置创建一个物理 XML 文件。 （我使用了您的 xml 并打包了 example.xml）

2. 打开 Visual Studio 命令提示符

3. 导航到目录

4. 键入 ' xsdsample.xml'（不带引号）这将生成sample.xsd

5. 类型为'xsd Sample.xsd /c'（不带引号）这将生成sample.cs

设置使用 Microsoft Visual Studio 2008 的环境x86 工具。

C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC>G:

G:\>xsd sample.xml
Microsoft (R) Xml Schemas/DataTypes support utility

有点乱，但是节省了你很多时间和精力。
