I am developing an application which will run on Windows OS. However, when run it on Windows Vista, my application's settings is stored in VirtualStore. How to check VirtualStore is being applied in my application (I need a function to check and it must ok on XP, Vista).

And how to get the path of Virtual Store of my application.

My workaround...

You get the user Appdata path:

String appdata = System.Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData);

Add VirtualStore folder to path:

String VirtualStoreRoot = appdata + "\\VirtualStore";

Create folder:

String backuppath = "C:\\Program Files\\Progname\\backup";
Directory.CreateDirectory(backuppath);

Check created in VirtualStore

String newpath = VirtualStoreRoot + backuppath.Substring(2);
if (Directory.Exists(newpath)){
   backuppath = newpath;
}

I found another stuff:

Isolated Storage with .NET

C# – How to cast int to enum

From an int:

YourEnum foo = (YourEnum)yourInt;

From a string:

YourEnum foo = (YourEnum) Enum.Parse(typeof(YourEnum), yourString);

// The foo.ToString().Contains(",") check is necessary for enumerations marked with an [Flags] attribute
if (!Enum.IsDefined(typeof(YourEnum), foo) && !foo.ToString().Contains(","))
{
    throw new InvalidOperationException($"{yourString} is not an underlying value of the YourEnum enumeration.")
}

Update:

From number you can also

YourEnum foo = (YourEnum)Enum.ToObject(typeof(YourEnum) , yourInt);

foreach (Suit suit in (Suit[]) Enum.GetValues(typeof(Suit)))
{
}

Note: The cast to (Suit[]) is not strictly necessary, but it does make the code 0.5 ns faster.
