如何将OpenApi.NET中的yaml扩展解析成.NET类？

using System;
using Microsoft.OpenApi.Extensions;
using Microsoft.OpenApi.Models;

// Step 2: 创建.NET类
public class MyModel
{
    public string Name { get; set; }
    public int Age { get; set; }
    // 其他属性...
}

class Program
{
    static void Main(string[] args)
    {
        // Step 3: 加载YAML文件
        var yamlContent = System.IO.File.ReadAllText("path/to/your/yaml/file.yaml");
        var document = OpenApiDocument.Load(yamlContent);

        // Step 4: 获取扩展
        var extensions = document.Extensions;

        // Step 5: 解析扩展字段
        if (extensions.TryGetValue("x-my-extension", out var myExtension))
        {
            // 解析myExtension字段并赋值给对应的属性
            var myModel = new MyModel
            {
                Name = myExtension["name"].ToString(),
                Age = Convert.ToInt32(myExtension["age"])
                // 其他属性...
            };

            // 打印解析得到的结果
            Console.WriteLine($"Name: {myModel.Name}");
            Console.WriteLine($"Age: {myModel.Age}");
        }
        else
        {
            Console.WriteLine("The x-my-extension field is missing in the YAML file.");
        }
    }
}
