hi, i cannot find the answer of this in the net.

string a = "4.00";
double d = Convert.ToDouble(a);
double d1 = d * 3;
MessageBox.Show(d1.ToString());

it displays "1200" but i want it to display 12.0 or 12.

How can i convert the string "4.00" to double 4.00 because it converts the string "4.00" to double 400.

thanks in advance
