Problem with two Values

[redrose4u293]

 private void profitbefore()
        {
            decimal final = 0;
            decimal fullfinal = 0;
            if(decimal.TryParse(txtprofitbefore.Text,out final) && decimal.TryParse(txtfinal.Text,out fullfinal))
            {
                
                decimal finalfull = final - fullfinal;
                txtbeforeexp.Text = finalfull.ToString("#,##0.00");
            }
        }

If you always want a positive number consider the following language extension.

public static class Extensions
{
    public static T ToPositive<T>(this T source) where T : INumber<T> 
        => T.IsNegative(source) ? -source : source;
}

Usage

int value = -5;
value = value.ToPositive();

Don't know if this is any good for you.

            int neg = -5;
            if(neg < 0)
            {
                neg = (-neg);
            }
            MessageBox.Show
                (neg.ToString());
