WPF, How can I call an OpenFolderDialog and load the content of a folder or subfolders in a listbox ...

Question

Good morning dear friends.
I have a small project. It is a loader of text file names in a ListBox and that in turn allows me to select them and then be able to record or write them in a * .INI file that is already selected with its path.

The "Open Folder" button shows an OpenFolderDialog and loads the path of the selected folder in a TextBox and this in turn loads in the LisBox all the text files.txt located in the chosen folder and also in the subfolders of the main folder .

The texts selected in the ListBox are written or saved in a TextList.ini file (for example), and those that are not selected are deleted from the TextList.ini file. Please I hope you can help me, I have also created a video so that I can have a better reference and I have attached some images as well.

You can use both OpenFolderDialog and FolderBrowserDialog after you adding the System.Windows.Forms.dll in the project's reference.
Code to get the folder location:

 private void btnOpen_Click(object sender, RoutedEventArgs e)  
        {  
            System.Windows.Forms.FolderBrowserDialog openFileDlg = new System.Windows.Forms.FolderBrowserDialog();  
            var result = openFileDlg.ShowDialog();  
            if (result.ToString() != string.Empty)  
            {  
                txtPath.Text = openFileDlg.SelectedPath;  
            }  
            root = txtPath.Text;  
        }  

Code to get the txt in folder and subfolders:

private void Button_Click(object sender, RoutedEventArgs e)  
        {  
            lt = new ObservableCollection<MyModel>();  
            string[] dicFileList = Directory.GetFiles(root, "*.txt", SearchOption.AllDirectories);  
            foreach (string element in dicFileList)  
            {  
                myModel = new MyModel();  
                //myModel.Name = System.IO.Path.GetFileName(element);  
                myModel.Name = System.IO.Path.GetFileNameWithoutExtension(element);  
                myModel.StatusForCheckBox = false;  
  
                lt.Add(myModel);  
            }  
            myList.ItemsSource = lt;  
        }  

You can create a field public bool StatusForCheckBox { get; set;} for MyModel to identity selected or not:

 private void Save_Click(object sender, RoutedEventArgs e)  
        {  
            List<string> ltForSave = new List<string>();  
            foreach (MyModel obj in myList.ItemsSource)  
            {        
                if(obj.StatusForCheckBox==false)  
                {  
                    ltForSave.Add(";" + obj.Name);  
                }else  
                {  
                    ltForSave.Add(obj.Name);  
                }  
            }  
            //Save ltForSave as ini file.      
        }  

Use the listbox like:

<ListBox x:Name="myList" Width="400" Height="400" HorizontalAlignment="Right">  
            <ListBox.ItemTemplate>  
                <DataTemplate >  
                    <CheckBox Content="{Binding Name}" IsChecked="{Binding StatusForCheckBox,Mode=TwoWay}"/>  
                </DataTemplate>  
            </ListBox.ItemTemplate>  
        </ListBox>

Hi well, the problem is that WPF does not have an "OpenFolderDialog", or "Browser Folder Dialog", is there any way that a button can be implemented in my project that shows me the path of a folder in a "textbox", and looks for * .txt files inside of the folder and subfolders, which I would like to see in a Listbox with checkboxes.

• These same names selected in the "checkbox", of the "listbox", I want to write them in a * .ini file. For example: "list of names.ini"

The file "list of names.ini" must have the following parameters:

[Super_Hero.List]
ActiveText = Batman
ActiveText = Superman
ActiveText = Spaiderman

I also have a button which updates the listbox to add or remove selected names and another button that saves the file "list of names.ini"

I hope it can be done and you have the generous help you can give me, thank you very much in advance friend, PeterFleischer-3316

I made a video with powerpoint to illustrate the project.

You can use System.Windows.Forms.FolderBrowserDialog to open the folder, and you can use it like below to get the path.

System.Windows.Forms.FolderBrowserDialog openFileDlg = new System.Windows.Forms.FolderBrowserDialog();  
            var result = openFileDlg.ShowDialog();  
            if (result.ToString() != string.Empty)  
            {  
                txtPath.Text = openFileDlg.SelectedPath;  
            }  

I will show you my demo to get content for folders and subfolders.
The code for MainWindow.xaml

 <Grid>  
        <TextBox Width="200" Height="35" VerticalAlignment="Top" HorizontalAlignment="Left" Margin="0 20 0 0" Name="txtPath"></TextBox>  
        <Button Content="Open" Width="80" Height="35" VerticalAlignment="Top" HorizontalAlignment="Left" Margin="250 20 0 0" Name="btnOpen" Click="btnOpen_Click" />  
        <Button Width="100" Height="50" Content="ShowFolder" Click="Button_Click" HorizontalAlignment="Left"></Button>  
        <Button Width="200" Height="40" Content="ShowFolder+SubFolder" Click="Button_Click2" HorizontalAlignment="Left" Margin="1,245,0,124"></Button>  
        <ListBox x:Name="myList" Width="400" Height="400" HorizontalAlignment="Right">  
            <ListBox.ItemTemplate>  
                <DataTemplate >  
                    <CheckBox  Content="{Binding Name}"/>  
                </DataTemplate>  
            </ListBox.ItemTemplate>  
        </ListBox>  
    </Grid>  

The code for MainWindow.xaml.cs:

public partial class MainWindow : Window  
    {  
        string root = "";  
         MyModel myModel;  
        public MainWindow()  
        {  
            InitializeComponent();  
             
        }  
        private void btnOpen_Click(object sender, RoutedEventArgs e)  
        {  
            System.Windows.Forms.FolderBrowserDialog openFileDlg = new System.Windows.Forms.FolderBrowserDialog();  
            var result = openFileDlg.ShowDialog();  
            if (result.ToString() != string.Empty)  
            {  
                txtPath.Text = openFileDlg.SelectedPath;  
            }  
            root = txtPath.Text;  
        }  
        private void Button_Click(object sender, RoutedEventArgs e)  
        {  
            //Show Folders  
            List<MyModel> lt = new List<MyModel>();  
            System.IO.DirectoryInfo d = new System.IO.DirectoryInfo(root);  
            System.IO.DirectoryInfo[] ds = d.GetDirectories("*.*", System.IO.SearchOption.TopDirectoryOnly);  
            foreach (System.IO.DirectoryInfo var in ds)  
            {  
                myModel = new MyModel();  
                myModel.Name = var.Name;  
                lt.Add(myModel);  
            }  
            myList.ItemsSource = lt;   
        }  
        private void Button_Click2(object sender, RoutedEventArgs e)  
        {  
            //Show all Folders and SubFolder  
            List<MyModel> myModels = new List<MyModel>();  
            GetAllFolder(root, myModels);  
            myList.ItemsSource = myModels;  
        }  
        public List<MyModel> GetAllFolder(string path, List<MyModel> myModels)  
        {  
            System.IO.DirectoryInfo d = new System.IO.DirectoryInfo(path);  
            System.IO.DirectoryInfo[] ds = d.GetDirectories("*.*", System.IO.SearchOption.TopDirectoryOnly);  
            FileInfo[] fil = d.GetFiles();  
            DirectoryInfo[] dii = d.GetDirectories();  
  
            foreach (System.IO.DirectoryInfo var in ds)  
            {  
                myModel = new MyModel();  
                myModel.Name = var.Name;  
                myModels.Add(myModel);  
            }  
            foreach (DirectoryInfo dd in dii)  
            {  
                GetAllFolder(dd.FullName, myModels);  
            }  
             
            return myModels;  
        }  
  
         
    }  
    public class MyModel  
    {  
        public string Name { get; set; }  
    }

Miss "DaisyTian-MSFT", good morning.
I appreciate your help, and managed to open and reproduce the first part of your demo and make the openfolder dialog and subfolders work, I had to attach the following using:

using System.IO;
using WinForms = System.Windows.Forms;
using Microsoft.Win32;
using System.Diagnostics;

But I still can't make it so that I can filter the text files and that they appear in the "Listbox" and I can also save them in a * .ini file, could you show me that in more detail, I send you the project so that you can see it and help me please and thank you very much for your time.

I put the link of the project. I use visual studio 2019 wpf.

Miss "DaisyTian-MSFT", good morning and thank you very much for your time.

Test your Demo Project, and added an "OpenFileDialog" button to find the .ini file, for example "ListTextFile.ini" and a Textbox to specify the path of the .ini file. Which works fine, thanks to your help.
How do I so that the names of the selected files in the Listbox can be written and saved in the * .ini file (ListTextFile.ini).

I put two images of the project and the other of the * .ini file format inside. To be able to express myself better. I also attached a new link to the modified project so that you can do the tests.
