将ObjectResult<int?>转换为List<int>

using Microsoft.AspNetCore.Mvc;
using System.Collections.Generic;
using System.Linq;

public class MyController : ControllerBase
{
    public IActionResult MyAction()
    {
        // 假设这里返回的是一个ObjectResult<int?>对象
        ObjectResult<int?> result = GetObjectResult();

        // 获取ObjectResult<int?>中的值
        int? value = result.Value;

        // 判断值是否为null
        if (value == null)
        {
            return new List<int>(); // 返回空的List<int>
        }

        // 将值转换为List<int>
        List<int> list = new List<int> { value.Value };

        return list;
    }

    private ObjectResult<int?> GetObjectResult()
    {
        // 这里可以是获取ObjectResult<int?>的逻辑
        // 例如，从数据库或其他数据源获取数据并返回ObjectResult<int?>
        return new ObjectResult<int?>(42);
    }
