C# 将实体的一部分选择到具有子对象的自定义对象中

我有这样一个实体框架查询-

var query = from tbl in db.myTable
            select new MyModel
            {
               id = tbl.id,
               start = tbl.start,
               end = tbl.end
            }

public class MyModel
{
   public int id {get; set;}
   public string _start {get; set;}
   public string _end {get; set;}
   public Range range {get; set;} // contains start and end property
}

我的模型如下-

public class MyModel
{
   public int id {get; set;}
   public Range range  {get; set;} // contains start and end property
}

在查询select中是否仍然存在将myTable的属性映射到range.start和range.end的方法

我发现唯一可行的方法就是向模型中添加额外的属性，就像这样-

var query = from tbl in db.myTable
            select new MyModel
            {
               id = tbl.id,
               start = tbl.start,
               end = tbl.end
            }

public class MyModel
{
   public int id {get; set;}
   public string _start {get; set;}
   public string _end {get; set;}
   public Range range {get; set;} // contains start and end property
}

然后在查询完成后运行一些代码，将_start映射到range.start和_end映射到range.end

问题是我预见到需要从实体将开始/结束映射到许多自定义子模型中。我需要始终从公共文件导入函数，并记住在查询运行后运行它。如果可以直接在select-like中映射它们，那么会更干净-

var query = from tbl in db.myTable
            select new MyModel
            {
               id = tbl.id,
               range.start = tbl.start,
               range.end = tbl.end
            }

或

你是说像这样

var query = from tbl in db.myTable
            select new MyModel
            {
               id = tbl.id,
               range = new Range
               {
                   start = tbl.start,
                   end = tbl.end
               }
            }

是的，非常简单，有点无聊。谢谢你的帮助。想想看，你不能做像range=newrangetbl.end，tbl.start这样的事情，这让我有点不舒服。再次感谢！
