Filter and give back a new object with Linq

Simulating the current situation:

class MyDTO{
int Id {get;set;}
int IdOfSomethingElse{get;set;}
string Description {get;set;}
string Description2 {get;set;}
}

class MyDTO{
int Id {get;set;}
int IdOfSomethingElse{get;set;}
string Description {get;set;}
string Description2 {get;set;}
}

var myDTOList = new List<MyDTO>()
{
    new MyDto{
    Id = 1,
    IdOfSomethingElse = 2,
    Description = "blabla1",
    Description2 = "blabla11"
    },

     new MyDto{
    Id = 2,
    IdOfSomethingElse = 2,
    Description = "blabla2",
    Description2 = "blabla22"
    }


     new MyDto{
    Id = 2,
    IdOfSomethingElse = 3,
    Description = "blabla3",
    Description2 = "blabla33"
    },

     new MyDto{
    Id = 4,
    IdOfSomethingElse = 3,
    Description = "blabla4",
    Description2 = "blabla44"
    }
}

How can I transform myDTOList to a new object with linq to the following object:

class MyNewDTO{
   int IdOfSomethingElse= 2
   List<string> descriptionList = will contain description of idofsomethingelse
   List<string> descriptionList2 = will contain description2 of idofsomething else

}

var myDTOList = new List<MyDTO>()
{
    new MyDto{
    Id = 1,
    IdOfSomethingElse = 2,
    Description = "blabla1",
    Description2 = "blabla11"
    },

     new MyDto{
    Id = 2,
    IdOfSomethingElse = 2,
    Description = "blabla2",
    Description2 = "blabla22"
    }


     new MyDto{
    Id = 2,
    IdOfSomethingElse = 3,
    Description = "blabla3",
    Description2 = "blabla33"
    },

     new MyDto{
    Id = 4,
    IdOfSomethingElse = 3,
    Description = "blabla4",
    Description2 = "blabla44"
    }
}

How can I transform myDTOList to a new object with linq to the following object:

class MyNewDTO{
   int IdOfSomethingElse= 2
   List<string> descriptionList = will contain description of idofsomethingelse
   List<string> descriptionList2 = will contain description2 of idofsomething else

}

Entityframework .Select vs Mapping method [Answered]

Is the following the same or has it performance difference?

var myList = await _dbContext.SomeList.Select(x => new myDTO{...}.ToListAsync();

var myList = await _dbContext.SomeList.Select(x => new myDTO{...}.ToListAsync();

var myData = await _dbContext.SomeList.ToListAsync();
var myList = MapToMyDTO(myData);

var myData = await _dbContext.SomeList.ToListAsync();
var myList = MapToMyDTO(myData);
