<p>i want to ask, how do i set condition or expression where the column table is type of <code>timespan</code>.

<pre><code>private void button1_Click(object sender, EventArgs e)
    {
        string expression2;
        expression2 = "timeOnlyStart &lt; '" + TimeSpan.Parse("10:00:00") + "'";
        DataTable yyy = dt_Main.Select(expression2).CopyToDataTable();
