Describe the additions or enhancements you'd like
It would be great if you could provide a way to let us get/set ShellItem(s) through NativeClipboard class easily.
The function like the example below:

public void SetShellItems(IEnumerable<ShellItem> Items)
{
    //Set items to underlying clipboard
}

public IEnumerable<ShellItem> GetShellItems()
{
    //Get items from underlying clipboard
}

Does Vanara.Windows.Shell.ShellDataObject have what you want?

[zhuxb711]

But ShellDataObject rely on System.Windows.Forms which is not friendly to use if someone who do not use WinForms.

[dahall]

Got it. Let me see if I can port the ShellDataObject code without the Forms dependencies.

[zhuxb711]

Thanks, do you have any demo to tell us how to use ShellDataObject with ShellItem (Includes Get/Set ShellItem and Set ShellItem with something custom data which stored in another clipboard id)

I added a couple methods to NativeClipboard. Give them a try and let me know your thoughts.

[zhuxb711]

Due to NativeClipboard not working in my project, I have not be able to test that but I reviewed the code, it looks great. #355 (comment)

[dahall]

I'll see if I can troubleshoot #355 over the next few days.

I found some issues, I could not retrieve the ShellItem which I just set into clipboard

            IEnumerable<ShellItem> Items = Collection.Select((Item) => new ShellItem(Item.Path));

            try
            {
                NativeClipboard.SetShellItems(Items);

                if (NativeClipboard.GetShellItemArray() is ShellItemArray Array)
                {
                    foreach (ShellItem Item in Array)
                    {
                        System.Diagnostics.Debug.WriteLine($"Shell IDList: {Item.FileSystemPath}");
                    }
                }
                else
                {
                    //Runs to here which means no available Shell IDList Array
                    System.Diagnostics.Debug.WriteLine("No available Shell IDList Array");
                }
            }
            catch (Exception)
            {

            }
            finally
            {
                Items.ForEach((Item) => Item.Dispose());
            }

The latest AppVeyor package seems to be working. I used this code behind a button in a WinForms project and consistently got what I expected.

string[] fileNames = new[] { @"C:\file1.txt", @"C:\file2.txt" };
NativeClipboard.SetShellItems(fileNames.Select(ShellItem.Open));
MessageBox.Show(string.Join("\n", NativeClipboard.GetShellItemArray().Select(i => i.FileSystemPath)));

[zhuxb711]

Demo for you. Could set the ShellItem but could not retrieve them back

I think this is now complete.
