C# Web API 嵌套在存储过程中的 JSON

Question

概述：

I'm building an API using ASP.NET Web API 2. I'm building Stored Procedures in SQL and linking these in the API to serve data.

例如，我知道 SQL 可以使用FOR JSON AUTO返回 JSON 。 但是，我认为这不是配置数据和输出JSON的最佳位置。 所以我假设必须有一种方法可以在 API 中实现嵌套的 JSON。

这就是我想要实现的目标：

    {
        "Apps": [
            {
                "ItemID": "1",
                "Path": "/AppReport",
                "Name": "AppReport",
                "Reports": [
                    {
                        "Reports_ItemID": "11",
                        "Reports_Path": "/AppReport/SubReport",
                        "Reports_Name": "SubReport"
                    },
                    {
                        "Reports_ItemID": "12",
                        "Reports_Path": "/AppReport/SubReport2",
                        "Reports_Name": "SubReport2"
                    }
                ]
            },
            {
                "ItemID": "2",
                "Path": "/AppReport2",
                "Name": "AppReport2",
                "Reports": [
                    {
                        "Reports_ItemID": "22",
                        "Reports_Path": "/AppReport/SubReport",
                        "Reports_Name": "SubReport"
                    }
                ]
            }
        ]
    }

目前它以平面Objects Array的形式出现

    {
        "Apps": [
            {
                "ItemID": "1",
                "Path": "/AppReport",
                "Name": "AppReport",
                "Reports_ItemID": "11",
                "Reports_Path": "/AppReport/SubReport",
                "Reports_Name": "SubReport"
            },
            {
                "ItemID": "1",
                "Path": "/AppReport",
                "Name": "AppReport",
                "Reports_ItemID": "12",
                "Reports_Path": "/AppReport/SubReport2",
                "Reports_Name": "SubReport2"
            },

            ...
        ]
    }

我在 API 中有一个存储过程的 class，如下所示：

    namespace API.Stored_Procedures
    {
        public partial class SP_GetApps
        {
            public System.Guid ItemID { get; set; }
            public string Path { get; set; }
            public string Name { get; set; }
            public System.Guid Report_ItemID { get; set; }
            public string Report_Path { get; set; }
            public string Report_Name { get; set; }
        }

    }

我的 Controller 看起来像这样：

    [HttpGet]
    [Route("{uid}", Name ="getReportApps")]
    [ResponseType(typeof(SP_GetApps_Result))]
    public IHttpActionResult SP_GetApps(string uid)
    {
        var res = db.Database.SqlQuery<SP_GetApps_Result>
            ("SP_GetApps {0}", uid);

        return Ok(res);
    }

为了实现所需的 JSON Class 应该看起来像

public class App
{
    public string ItemID { get; set; }
    public string Path { get; set; }
    public string Name { get; set; }
    public List<Report> Reports { get; set; }
}

public class Report
{
    public string Reports_ItemID { get; set; }
    public string Reports_Path { get; set; }
    public string Reports_Name { get; set; }
}
