【问题描述】：

我是 .net 核心编程的新手。

我在如何格式化我的 Json 对象时遇到问题。我想创建一个 Json 对象，并且该 Json 的字段之一将处理 Json 对象。

我正在使用 MVC 架构。谢谢

这是我的代码。

    public async Task<List<Schedule>> getAllScheds(){
        dynamic response = new JObject();
        try {

            var data = await _context.MlfbSchedules
                        .Include(h => h.Team1)
                        .Include(a => a.Team2)
                        .Include(s => s.StadiumID)
                        .ToListAsync();
            return data;
        } catch (Exception e) {
            response.Error = e.ToString();
            return response;
        }

    }

此函数正在返回此数据。

我想返回一个与此类似的Json对象。

使用布尔属性 Success 和 List 属性 Data 创建一个类。并填充该类的对象并从方法返回
布尔属性？如何？你有样品吗/
你必须使用模型类和 DTO
怎么样？能详细点吗？

标签： c# json api .net-core asp.net-core-mvc

【解决方案1】：

为了格式化响应，您可以实现自己的 Dto，如下所示：

    public class ResultDto<T> where T : class
{
    public ResultDto(string status, IList<T> data)
    {
        Status = status;
        Data = data;
    }
    public string Status { get; set; }
    public IList<T> Data { get; set; }
}

然后像

这样改变你的方法

        public async Task<ResultDto<Product>> getAllScheds()
    {
        dynamic response = new JObject();
        try
        {

            var data = new List<Product>
                     {
                         new Product{ProductId=Guid.NewGuid().ToString(),Name="142525"},
                         new Product{ProductId=Guid.NewGuid().ToString(),Name="122555"},
                         new Product{ProductId=Guid.NewGuid().ToString(),Name="125255"}
                     };
            return new ResultDto<Product>("success", data);
        }
        catch (Exception e)
        {
            response.Error = e.ToString();
            return response;
        }

    }

【讨论】：

我要为此在我的模型文件夹中添加一个新类吗？公共类 ResultDto 其中 T : 类
@Novice 是的。您需要创建一个新的 dto
所以我需要为那个 DTO 创建一个新的控制器，对吧？还是我只编辑我现有的？
@Novice 这取决于你的要求，如果你只需要status and data json，修改现有的，如果你需要status and data 和data，创建一个新方法。
