converting from string to float problem

[ool]

Hello,

How I can convert value from string to double.

When I do this in that way:

String sParam="150.00" ;
double dbValue= Convert.ToDoubl e(szParam);

I get System.FormatEc xeption

Thomas,

You might find the either Double.Parse or Double.TryParse to be a bit more
useful than Convert.ToDoubl e.

A hunch.

I note that your post seems to originate from Poland, yes? According to
Windows, the Polish culture uses a comma to seperate whole part from decimal
part. Assuming the number you are trying to parse follows the English (U.S.)
format, you could create a CultureInfo object and pass it as the second
(IFormatProvide r) parameter to the Convert.ToDoubl e method.

System.Globaliz ation.CultureIn fo enUSCulture =
new System.Globaliz ation.CultureIn fo("en-US");

String sParam = "150.00";
double dbValue = Convert.ToDoubl e(szParam, enUSCulture);

I presume your actual code has the same variable name in both places.

My guess is that you're in a culture where the decimal point is a comma
rather than a dot. Try

double dbValue = Convert.ToDoubl e (szParam,
CultureInfo.Inv ariantCulture);

(with a using System.Globaliz ation; statement at the top of your code).
