C# 如何将记录从可枚举模型列表存储到字符串数组中

我试图将记录列表按给定格式存储到字符串数组中。我已经给出了布局的格式，因为给定的数据需要存储在字符串数组myData中

为此，我有三个模型

   public class Depot
   {
       public  int Id { get; set; }
       public string  DepoName { get; set; }
   }
   public class Department
   {
       public int Id { get; set; }
       public string  DepartmentName { get; set; }
   }
   public class DepotDepartmentLink
   {
       public int Id { get; set; }
       public int DepotId { get; set; }
       public int DepartmentId { get; set; }
       public Depot Depot { get; set; }
       public Department Department { get; set; }
   }

在存储库类中

   public IEnumerable<DepotDepartmentLink> GetAllDepotDepartmentLink()
   {         
      return _db.DepotDepartmentLink.Include(m => m.Depot).Include(m=>m.Department);
   }

public IEnumerable GetAllDepotDepartmentLink（）
{         
return _db.DepotDepartmentLink.Include（m=>m.Depot）.Include（m=>m.Department）；
}

在控制器中，我试图将结果中的数据按照上面给定的格式带入数组myData。请帮忙

   public IActionResult Index()
   {    
       IEnumerable<DepotDepartmentLink> depotdepartment = _depotDepartmentLinkRepo.GetAllDepotDepartmentLink();
       string myData = "[]";
      
       myData = "[" + string.Join(",",depotdepartment.Select(l => l.DepotId + "." + l.DepartmentId).ToArray());    
       return View();
   }

public IActionResult Index（）
{    
IEnumerable DepotDepartDepartment=_DepotDepartDepartmentLinkRepo.GetAllDepotDepartDepartmentLink（）；
字符串myData=“[]”；
myData=“[”+string.Join（“，”，depotdepartment.Select（l=>l.DepotId+”+l.DepartmentId.ToArray（））；
返回视图（）；
}

这是一个简单的数据分组。它使用LINQ完成。
然后我们使用任何序列化程序获取json

var result = depotdepartment
    .GroupBy(dd => new { dd.DepotId, dd.Depot.DepoName })
    .Select(g => new
    {
        id = g.Key.DepotId,
        title = g.Key.DepoName,
        subs = g.Select(dd => new
        {
            id = dd.DepotId + "." + dd.DepartmentId,
            title = dd.Depot.DepoName + "." + dd.Department.DepartmentName
        })
    });

string json = JsonConvert.SerializeObject(result, Formatting.Indented);

您是否尝试使用JSON序列化？要转换为JSON sting数组，无论是要在视图中显示的对象还是其他对象，都必须序列化添加引用newtonsoft和类似字符串jstr=JsonConvert.SerializedObject（depotdepartment，Formatting.Indented）；请您根据我的示例指导我如何转换为json字符串arrayChetan，我按照您的建议进行了尝试，但不起作用。因为字符串数组应以与上面所附格式相同的格式传递，并且

DepotDepartmentLink

包含。。。？

   public IActionResult Index()
   {    
       IEnumerable<DepotDepartmentLink> depotdepartment = _depotDepartmentLinkRepo.GetAllDepotDepartmentLink();
       string myData = "[]";
      
       myData = "[" + string.Join(",",depotdepartment.Select(l => l.DepotId + "." + l.DepartmentId).ToArray());    
       return View();
   }

var result = depotdepartment
    .GroupBy(dd => new { dd.DepotId, dd.Depot.DepoName })
    .Select(g => new
    {
        id = g.Key.DepotId,
        title = g.Key.DepoName,
        subs = g.Select(dd => new
        {
            id = dd.DepotId + "." + dd.DepartmentId,
            title = dd.Depot.DepoName + "." + dd.Department.DepartmentName
        })
    });

string json = JsonConvert.SerializeObject(result, Formatting.Indented);
