You have to do this by two way

(1) One way using dropdownlist SelectedItem propety

lbltest.Text = ddlexpyear.SelectedItem.Text + "." + ddlexpmonth.SelectedItem.Text;
double test = Convert.ToDouble(lbltest.Text);

(2) Another way using dropdownlist SelectedValue propety

 lbltest.Text = ddlexpyear.SelectedValue + "." + ddlexpmonth.SelectedValue;
 double test= Convert.ToDouble(lbltest.Text);

If google then you have definitely find out.

I hope it’s help you.
