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，因此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，但它并没有完全工作（事实上，其中的一些是明显错误的）。有任何想法吗？

// 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，这是完全错误的，所有我需要做的就是看看它实现了数据结构不会映射到所需的XML。真正抛出我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用。
感谢所有谁提供的解决方案

下面是一个简单的项目。

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

那么这里就是你所需要的代码。

[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"); 
    } 
}

示例XML：

<chart> 
    <series> 
    <value xid="0">0</value> 
    <value xid="0">0</value> 
    <value xid="0">0</value> 
    </series> 
    <graphs> 
    <graph gid="1"> 
     <value xid="0" color="0">0</value> 
     <value xid="0" color="0">0</value> 
     <value xid="0" color="0">0</value> 
    </graph> 
    <graph gid="1"> 
     <value xid="0" color="0">0</value> 
     <value xid="0" color="0">0</value> 
     <value xid="0" color="0">0</value> 
    </graph> 
    <graph gid="1"> 
     <value xid="0" color="0">0</value> 
     <value xid="0" color="0">0</value> 
     <value xid="0" color="0">0</value> 
    </graph> 
    </graphs> 
</chart> 

类：

[XmlRoot("chart")] 
public class BarChartSeriesEntity 
{ 
    [XmlElement("series")] 
    public BarChartSeriesValue[] SeriesValues { get; set; } 
    [XmlElement("graphs")] 
    public BarChartGraphsValue[] GraphsValues { get; set; } 

    public class BarChartSeriesValue 
    { 
     [XmlElement("value")] 
     public SeriesValueEntity[] Values { get; set; } 
    } 

    public class SeriesValueEntity 
    { 
     [XmlAttribute("xid")] 
     public string Xid { get; set; } 
     [XmlText] 
     public string Value { get; set; } 
    } 


    public class BarChartGraphsValue 
    { 
     [XmlElement("graph")] 
     public BarChartGraphValue[] Graphs { get; set; } 
    } 

    public class BarChartGraphValue 
    { 
     [XmlAttribute("gid")] 
     public string Gid { get; set; } 
     [XmlElement("value")] 
     public GraphValueEntity[] Values { get; set; } 
    } 

    public class GraphValueEntity 
    { 
     [XmlAttribute("xid")] 
     public string Xid { get; set; } 
     [XmlAttribute("color")] 
     public string Color { get; set; } 
     [XmlText] 
     public string Value { get; set; } 
    } 
}

您可以使用XSD.exe生成类，我认为它是Visual Studio的一部分。

如果打开Visual Studio命令提示符，您可以访问它。

1. 在硬盘的某个地方创建一个物理XML文件。 （我用了你的XML和装箱sample.xml中）

2. 打开Visual Studio命令提示符

3. 导航到该目录

4. 型 'XSD sample.xml中'（不带引号），这将生成（没有引号）在 'XSD sample.xsd/C' sample.xsd

5. 类型，这将产生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]

生成：
