将 YAML 反序列化为自定义类型

我目前正在尝试将 YAML 文档反序列化为标准 .NET 对象，例如string对于标量值和Dictionary<string, object>对于映射，使用 YamlDotNet 库。

我猜可能是Deserializerclass 是最好的选择，但它的输出是object and Dictionary<object>。我尝试实施自定义INodeTypeResolver像这样：

class MyNodeTypeResolver : INodeTypeResolver
{
    bool INodeTypeResolver.Resolve(NodeEvent nodeEvent, ref Type currentType)
    {
        if (currentType == typeof(object))
        {
            if (nodeEvent is SequenceStart)
                currentType = typeof(List<object>);
            else if (nodeEvent is MappingStart)
                currentType = typeof(Dictionary<string, object>);
            else if (nodeEvent is Scalar)
                currentType = typeof(string);

            return true;
        }

        return false;
    }
}

并像这样使用它：

Deserializer deserializer = new Deserializer();
deserializer.TypeResolvers.Add(new MyNodeTypeResolver());
var res = deserializer.Deserialize(input);

但这似乎没有任何效果。有什么方法可以改变生成的对象的类型Deserializer?

你走在正确的轨道上INodeTypeResolver但您需要构建并使用自定义反序列化器：

DeserializerBuilder deserializerBuilder = new DeserializerBuilder()
    .WithNodeTypeResolver(new MyNodeTypeResolver());
IDeserializer deserializer = deserializerBuilder.Build();
var res = deserializer.Deserialize(input);
