C# - Remove rows with the same column value from a DataTable

Question

I have a DataTable which looks like this:

 ID   Name    DateBirth
.......................
 1     aa      1.1.11
 2     bb      2.3.11
 2     cc

Heres a way to achive this, All you need to use moreLinq library use its function DistinctBy

Code:

protected void Page_Load(object sender, EventArgs e)
{
  var DistinctByIdColumn = getDT2().AsEnumerable()
                                   .DistinctBy(
                                   row => new { Id = row["Id"] });
  DataTable dtDistinctByIdColumn = DistinctByIdColumn.CopyToDataTable();
}


public DataTable getDT2()
{
   DataTable dt = new DataTable();
   dt.Columns.Add("Id", typeof(string));
   dt.Columns.Add("Name", typeof(string));
   dt.Columns.Add("Dob", typeof(string));
   dt.Rows.Add("1", "aa","1.1.11");
   dt.Rows.Add("2", "bb","2.3.11");
   dt.Rows.Add("2", "cc","1.2.12");
   dt.Rows.Add("3", "cd","2.3.12");
   return dt;
}
