返回 json api 中未显示的列表数据

Question

嗨，当我尝试从 api 请求中获取数据时，列表数据丢失了

[Route("/Calculators/{id}")]
        [HttpGet("{id}")]
   
        public CalcRequiredInputs Get(int id)
        {

            using (var context = new PiContext())
            {
                var calReqIn = new CalcRequiredInputs();
                calReqIn.CalObj  = context.TaskCalculators.Where(e => e.Id == id).ToList().ToList();
                calReqIn.ListOfRequiredInputs.Append("Dom");


                return calReqIn;
            }

            
        }



public class CalcRequiredInputs
{
    
    public List<string> ListOfRequiredInputs = new List<string>();
    public List<Calculator>? CalObj { get; set; }

}


public class Calculator
{
    public int Id { get; set; }
    public string CalculatorName { get; set; } = null!;
}

输出

{"calObj":[{"id":1,"calculatorName":"M2"}]}

ListOfRequiredInputs 丢失

Answer 1

这很可能是因为ListOfRequiredInputs 是一个字段而不是一个属性。请尝试以下操作：

public class CalcRequiredInputs
{
    public List<string> ListOfRequiredInputs {get;} = new List<string>();
    public List<Calculator>? CalObj { get; set; }
}
