Answer 1

void Main()
{
    var list = new []{
        new { LineId = 1 },
        new { LineId = 1 },
        new { LineId = 1 },
        new { LineId = 2 },
        new { LineId = 2 },
        new { LineId = 1 },
        new { LineId = 1 },
        new { LineId = 3 },
        new { LineId = 3 },
        new { LineId = 1 }
    };

    var groups =    
        from i in list
        group i by i.LineId into g
        select new { LineId = g.Key, MyObject = g };
}
