Converting "String" to "Double".

Question

Hi,

Can someone tell me how do i convert a "String" variable to a "Double" variable?

Thanks!

Answer 1

Try using the double.parse() method.

        string d = "1234.5";

        double m = double.Parse(d);

in addition, in .NET 2.0 there is a TryParse method. This allows you to check whether or not the string supplied is a double "compatible" type, in other words, checks to see if the value given can be converted to double. This is the preferred approach since doing a direct Parse can cause an exception if the string is not in the required format. If you know it is definately a double value from a string then yes use Parse. Example of using TryParse:

 

double theValue = 0;

if (double.TryParse("123.2", out theValue))

{

   //value was converted to double and result stored in "theValue"

}
