Question

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>

我最初想出了这个，但它没有完全奏效（事实上，其中一些是完全错误的）。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; }
}

当我说它只是完全错误时，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。真正抛弃我的部分是嵌套的图形结构我以前不知道通过XSD从XML生成类。它看起来非常有用和有用感谢所有提供解决方案的人

Answer 1

这是一个快速项目。

我使用这个类或它的变体： Generic XML Serializer Class for C# and an XML Serialization usage example

然后这是您需要的代码。

[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");
    }
}

Answer 2

您可以使用XSD.exe生成该类，我认为它是视觉工作室的一部分。

如果打开Visual Studio命令提示符，则可以访问它。

在某处的硬盘上创建一个物理XML文件。（我使用了你的xml和crated sample.xml）
打开Visual Studio命令提示符
导航到目录
输入'xsd sample.xml'（不带引号）这将生成sample.xsd
输入'xsd sample.xsd / c'（不带引号）这将生成sample.cs

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

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

G:\>xsd sample.xml
Microsoft (R) Xml Schemas/DataTypes support utility
[Microsoft (R) .NET Framework, Version 2.0.50727.3038]

示例Xml：

    <value xid="0">0</value>
    <value xid="0">0</value>
    <value xid="0">0</value>
  </series>
