Question

I’ve got a array of class in which one member is the full path to a file. I need to delete all those files from the directory which is not included in the array. As Usual, I am using the convential compare and delete method. I need to know if there any fast way to accomplish this.
I heard it can be done using Linq, but i dont have knowledge on linq.

My class struct is like below.

Class ImageDetails
{

public string Title;

public Boolean CanShow;

public String PathToFile;
}

I have an array of ImageDetails. The PathToFile contains full path

}

You can use Except() to handle this:

var filesToDelete = Directory.GetFiles(Path.GetDirectoryName(yourClass.FilePath)).Except(yourClass.TheArray);
