Folder Browser Dialog

Hi Daniel, if noone has replied to your StackOverflow/Microsoft Q&A post, you can take a look at Microsoft's MAUI Essentials FilePicker control

Note: Microsoft hasn't published the documentation for MAUI Essentials yest, but you can use the same exact instructions from this documentation => Xamarin.Essentials: File Picker - Xamarin | Microsoft Docs  (MAUI Essentials are the same thing as Xamarin Essentials).

For an example, look at the MAUI Essentials demos maui/FilePickerViewModel.cs at main · dotnet/maui (github.com)

Please read the material, just because it is called a "File" picker doesn't mean you cannot get a folder.  Or just Google/Bing the questions it and you'll see many conversations on the topic, here's the most recent one https://docs.microsoft.com/en-us/answers/questions/717736/folder-picker-in-xamarin-forms.html

It is also very important to remember that the mobile paradigm is VERY different than what you might be used to building WinForms or WPF apps. Mobile OS does not let you just get a full path due to the tighter security.

An easier way for you to do this would be just to show the user a list of safe folders that can select from using Environment.SpecialFolder enum Xamarin.Forms Directory Picker - Stack Overflow 

i will.

I see also https://stackoverflow.com/questions/70999773/folder-picker-net-maui

That's a good starting point, you just need to finish building the interfaces for iOS and Android. Then on those native platform concrete implementations, you can use the native iOS and Android APIs to list the folder paths.

Though, keep in mind, you still run into the same risk of the user not being able to safe store anything in those locations You could look at the source code for MAUI Essentials and see how James implements the native iOS and and Android APIs to iterate valid directories. Here's the GitHub repo with the source code maui/src/Essentials at main · dotnet/maui (github.com)

This code is not complied:

using WindowsFolderPicker = Windows.Storage.Pickers.FolderPicker;

namespace MauiFolderPickerSample.Platforms.Windows
{
    public class FolderPicker : IFolderPicker
    {
        public async Task<string> PickFolder()
        {
            var folderPicker = new WindowsFolderPicker();

            // Get the current window's HWND by passing in the Window object
            var hwnd = ((MauiWinUIWindow)App.Current.Windows[0].Handler.NativeView).WindowHandle;

            // Associate the HWND with the file picker
            WinRT.Interop.InitializeWithWindow.Initialize(folderPicker, hwnd);

            var result = await folderPicker.PickSingleFolderAsync();

            return result.Path;
        }
    }
}
