There is a class FileInfo (https://msdn.microsoft.com/en-us/library/system.io.fileinfo%28v=vs.110%29.aspx) - is this the array you mention or you just want some collection of the information about the files?

Assuming that you're using Windows Forms due to the use of the OpenFileDialog class, you can just use OpenFileDialog.Files to get the FileInfo structs of the various selected items.

Solution 1

Try this;

var fileInfos = openFileDialog.FileNames.Select(x => new FileInfo(x)).ToArray();

Remember to import System.Linq.

Hope this helps,
