Try

string columnNames = dt.Columns.Cast<DataColumn>()

                                 .Select(x => x.ColumnName)

                                 .ToArray();  

dataGridView1.DataSource = columnNames;

dataGridView1.DataSource = dt.Columns.Cast<DataColumn>()

                                 .Select(x => x.ColumnName)

                                 .ToArray();

I think it returns the length of the column. But it did change to vertically down a column. Can i know. Is this what they call LINQ?

Yes, this is LINQ . will return ColumnName and if you bind with Grid, will be shown vertically as needed.

the columnNames did store the row values in array. But when i set it to dataGridView1.DataSource it shows the property of the array. Not the values in it. Can i know how i can solve this?

Simply set the Header to be visible like this:

DataGridView.ColumnHeaderVisible = true;

This worked for me.
