%AppData% is a SpecialFolder.

change your code from:

path = @"%AppData%\Roaming\test\";

to:

var appDataPath = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData);
var path = Path.Combine(appDataPath, @"test\");
if (!Directory.Exists(path))
        Directory.CreateDirectory(path);
