Um.
I think you are mistaken:

C#

using (SqlConnection con = new SqlConnection(strConnect))
    {
    DataTable dt = new DataTable();
    SqlDataAdapter da = new SqlDataAdapter("SELECT TOP 100 Title from Videos", con);
    da.Fill(dt);
    Console.WriteLine("{0}:{1}", dt.Columns.Count, dt.Rows.Count);
    dt.Columns.Clear();
    Console.WriteLine("{0}:{1}", dt.Columns.Count, dt.Rows.Count);
    }

Gives:

1:100
0:100

So start by looking at your code, and see exactly what you are doing, and what you are trying to achieve.
