将根 XML 元素反序列化为数组

Question

我需要将 XML 中的多个字段保存到不同的数组中。 这就是我的 XML 的样子：

<Content>
    <Colours>
        <Colour name="Strong Red">
                <R>255</R>      
                <G>0</G>
                <B>0</B>
                <A>255</A> 
        </Colour>
    </Colours>
    <Textures>
         <Texture name="Character01">
             <Path>Path/Folder</Path>
         </Texture>
    </Textures>
</Content>

当<Colours> 是我的根并且我只将颜色添加到一个数组中时，现在一切正常。

现在我想通过同一个 XML 文件添加纹理，然后再添加更多，从而将根移到 <Content>。

这就是我的 ColourLoader 类的样子，只有颜色，<Colour> 是我的 XML 的根：

[Serializable()]
[XmlRoot("Colours")]
public class ColourLoader
{
    [XmlElement("Colour")]
    public CustomColour[] Colours;

    public static ColourLoader Load(string path)
    {
        var serializer = new XmlSerializer(typeof(ColourLoader));
        using (var stream = new FileStream(path, FileMode.Open))
        {
            return serializer.Deserialize(stream) as ColourLoader;
        }        
    }
}

我的 CustomColour 类工作正常，它使用 [XmlElement("R")] 等从 XML 读取值。只是我不知道如何从嵌套的 XML 中读取元素。 我必须以某种方式跳过<Content> 并从<Colours> 添加颜色作为root 并为<Textures> 等做同样的事情。

我不想创建多个 XML 文件，因为我想将所有内容管理到一个位置，并且只加载一次 XML 文件。

我想这就是你所追求的。我还包含了一个序列化对象的方法。我发现这对诊断 XML 序列化的特殊问题非常有帮助......

如果这解决了您的问题，请投票作为答案。

    [Serializable()]
    [XmlRoot("Content")]
    public class Content
    {
        [XmlArray("Colours")]
        [XmlArrayItem("Colour")]
        public CustomColour[] Colours { get; set; }

        [XmlArray("Textures")]
        [XmlArrayItem("Texture")]
        public CustomTexture[] Textures { get; set; }
    }

    [Serializable()]
    [XmlRoot("Colour")]
    public class CustomColour
    {
        [XmlAttribute("name")]
        public string Name { get; set; }

        [XmlElement("R")]
        public int R { get; set; }

        [XmlElement("G")]
        public int G { get; set; }

        [XmlElement("B")]
        public int B { get; set; }

        [XmlElement("A")]
        public int A { get; set; }
    }

    [Serializable()]
    [XmlRoot("Texture")]
    public class CustomTexture
    {
        [XmlAttribute("name")]
        public string Name { get; set; }

        [XmlElement("Path")]
        public string Path { get; set; }
    }

    public static class ContentLoader
    {
        public static Content Load(TextReader textReader)
        {
            var serializer = new XmlSerializer(typeof(Content));
            var ret = serializer.Deserialize(textReader) as Content;
            return ret;
        }

        public static void Save(TextWriter textWriter, Content content)
        {
            var serializer = new XmlSerializer(typeof(Content));
            serializer.Serialize(textWriter, content);
        }
    }

    public static void XmlSerializing()
    {
        var xml = @"<?xml version=""1.0"" encoding=""utf-16""?>
                    <Content xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" xmlns:xsd=""http://www.w3.org/2001/XMLSchema"">

                            </Colour>
                        </Colours>

                        </Textures>
                    </Content>";
        var reader = new StringReader(xml);
        var content = ContentLoader.Load(reader);

        Console.WriteLine("Deserialized version:");
        Console.WriteLine("  Colours");
        foreach (var colour in content.Colours)
        {
            Console.WriteLine("    R: {0}, G: {1}, B: {2}, A: {3}", colour.R, colour.G, colour.B, colour.A);
        }

        Console.WriteLine("  Textures");
        foreach (var texture in content.Textures)
        {
            Console.WriteLine("    Path: {0}", texture.Path);
        }

        var contentObj = new Content()
                            {
                                Colours = new[] { new CustomColour() { Name = "StrongRed", R = 255, G = 0, B = 0, A = 255 } },
                                Textures = new[] { new CustomTexture() { Name = "Character01", Path = "Path/Folder" } }

        Console.WriteLine(string.Empty);
        Console.WriteLine("Serialized version:");
        var writer = new StringWriter();
        ContentLoader.Save(writer, contentObj);
        Console.WriteLine(writer);
    }
