Re: Converting string to double

Hi, how can I parse string "? 20.000" to double ?


Well, you obviously need to remove the '?' character and space before
it can be parsed to any numerical format. So I would use the Split()
function to remove the '?' character and the Trim() function to remove
the space:

string strNumber = "? 20.000";
strNumber = strNumber.Split('?');
strNumber.Trim();

Then use the Convert.ToDouble() function to convert the string to a
double value:

double myVal = Convert.ToDouble(strNumber);

If the value you are converting should be represented as currency or
requires a certain degree of precision you should use the
String.Format() function after converting your value. I hope that helps.
