private void btnSubmit_Click(object sender, EventArgs e)

{

int numberOfDrawers = Convert.ToInt32(txtDrawers.Text);

char woodType = Convert.ToString(txtWood.Text);

double cost;

switch(woodType)

{

case 'p':

cost = (30 * numberOfDrawers) + 100;

lblDisplayTotal.Text = cost.ToString("C");

lblDisplayAll.Text = "Pine wood with " + numberOfDrawers + "drawers ";

break;

case 'm': cost = (30 * numberOfDrawers) + 180;

lblDisplayTotal.Text = cost.ToString("C");

blDisplayAll.Text = "Mahogany wood with " + numberOfDrawers + "drawers ";

break;

case 'o':

cost = (30 * numberOfDrawers) + 140;

lblDisplayTotal.Text = cost.ToString("C");

lblDisplayAll.Text = "Oak wood with " + numberOfDrawers + "drawers ";

break;

}

}

How can i get the letter than the user post for the wood type so that it can be used in my switch in its current state?
