Hello,
i am new to Electron.Net and have a question. I am not very familar with javascript btw.

I used the Electron.Net Api Demos to open a file dialog that allows multiple selection.
I nearly copied everything from DialogsController.

string[] files = await Electron.Dialog.ShowOpenDialogAsync(mainWindow, options); Electron.IpcMain.Send(mainWindow, "select-directory-reply", files);

files is an array.
I expected to get an array on the javascript side too.
But i only get a string. The related javascript code in the example expect only a single path.

The code in IpcMain goes over the array and creates multiple objects.
I think it was designed to do so. Right?

After i debugged the IpcMain code i decide to use :
'Electron.IpcMain.Send(mainWindow, "select-directory-reply", new object[] { files });'

Is that the simplest solution or do i miss something?
Should the example be edited to make it clearer how parameters should be passed?
