CultureInfo represents information about a culture. Here is an example of its use:
CultureInfo ci = new CultureInfo("de-AT"); // German-Austria
CultureInfo() with no parameters and Thread.CurrentThread.CurrentCulture return objects with current culture.
Use the instance method when the expression is used repeatedly, because, unlike the static approach, it does not have to recompile the expression each time.
Equals() is used to check the memory location. If different, a character-by-character comparison is performed.
a. FileInfo is not created from a FileStream.
