Thread.CurrentThread.CurrentUICulture = usCulture;
usCulture = Thread.CurrentThread.CurrentCulture;
dbNumberFormat = usCulture.NumberFormat;
number = decimal.Parse("1.332,23", dbNumberFormat); //123.456.789,00

usCulture = new CultureInfo("en-GB");
Thread.CurrentThread.CurrentCulture = usCulture;
Thread.CurrentThread.CurrentUICulture = usCulture;
usCulture = Thread.CurrentThread.CurrentCulture;
dbNumberFormat = usCulture.NumberFormat;
number = decimal.Parse("1,332.23", dbNumberFormat); //123.456.789,00
