How can we hide coloums at run time in datagridview?

for (int i = 0; i < dataGridView1.ColumnCount; i++)
{
     if (i == 0)
     {
           //set to Visible 
           dataGridView1.Columns[i].Visible = true;
     }
     else
     {
           dataGridView1.Columns[i].Visible = false;
     }
 
}

if (grdView.Rows.Count > 0)
{
grdView.Columns[2].Visible = false;
}
