YamlDotNet:如何自定义反序列化程序以处理具有不同类型的值的相同键

using YamlDotNet.Core;
using YamlDotNet.Serialization;

public class CustomTypeConverter : IYamlTypeConverter
{
    public bool Accepts(Type type)
    {
        // 判断是否适用于自定义类型的转换
        return type == typeof(MyCustomType);
    }

    public object ReadYaml(IParser parser, Type type)
    {
        // 读取YAML节点并将其转换为.NET对象
        var scalarNode = parser.Consume<Scalar>();
        var value = scalarNode.Value;

        // 根据值的类型进行适当的处理
        if (value == "true")
        {
            return new MyCustomType(true);
        }
        else if (value == "false")
        {
            return new MyCustomType(false);
        }
        else
        {
            return new MyCustomType(int.Parse(value));
        }
    }
}

public class MyCustomType
{
    public object Value { get; }

    public MyCustomType(object value)
    {
        Value = value;
    }
}

public class Program
{
    public static void Main()
    {
        var yaml = @"
key: true
key: false
key: 123
";

        var deserializer = new DeserializerBuilder()
            .WithTypeConverter(new CustomTypeConverter())
            .Build();

        var result = deserializer.Deserialize<MyCustomType>(yaml);

        Console.WriteLine(result.Value); // 输出: 123
    }
}
