C# - Save the last selected file names after closing DialogBox

Question

I have a button which will open a file dialog and choose 2 certificates.
After i click the button a windows will be shown from where i choose two certificates.

I click Open so i will get this two certs. What i want to do is that after i click Open and click again the Select Certificate button instead the empty filename textbox like this I want the last selection to be saved. Is it possible such a thing?

You mean you want to automatically re-select the previously selected items? — stuartd, Jun 08 '16 at 14:02
I know how to remember the directory, but not how to find the selected files. — drgmak, Jun 08 '16 at 14:04
Save the FileName string & set it before opening a second time. Note that there is a bug with this only setting part of the file name - workaround here http://stackoverflow.com/questions/17163784/default-name-with-openfiledialog-c — PaulF, Jun 08 '16 at 14:07

File**Names** is ReadOnly, but FileName isn't. – stuartd Jun 08 '16 at 14:11

Assign the FileName property when you create the dialog. It supports multiple files if you include quotes around the file names (full paths). See the example below:

var dialog = new OpenFileDialog
{
    Multiselect = true,
    FileName = @"""C:\example.txt"" ""C:\example2.txt"""
};
