CultureInfo result in visual studio is different between windows 8 and windows 10

Question

I found that CultureInfo class returns information such as number format which is different when executing in windows 8.1 and 10. I created a simple console application to conform which is given below. In windows 8.1 the result of conversion is 2235. But in windows 10 the result is 0. I am using visual studio 2013 in both environment.

        CultureInfo cultureInfo = new CultureInfo(3079);
        System.Threading.Thread.CurrentThread.CurrentCulture = cultureInfo;
        System.Threading.Thread.CurrentThread.CurrentUICulture = cultureInfo;

        string value = "2.235";
        decimal test;
        decimal.TryParse(value, NumberStyles.Any, cultureInfo, out test); 

Please let me know if you need any further information to give a clear picture.

Answer 1

This

CultureInfo cultureInfo = new CultureInfo(3079);

is the same as

CultureInfo cultureInfo = new CultureInfo("de-AT");

It's the austrian culture. They use comma as decimal separator but space as thousands separator(as opposed to germans who use . for thousands).

So this works (appended ,99 for clarity, you can remove it):

string value = "2 235,99";
bool valid = decimal.TryParse(value, NumberStyles.Any, new CultureInfo("de-AT"), out test);

But this format not: string value = "2.235,99"

So it has nothing to do with your OS version.

Note that you should always store the result of TryParse ( bool ) in a variable or use an if...else instead of using the returned out value to determine whether it could be parsed or not. Even 0 could be a valid value.
