How to use OpenFileDialog to select folders?
I was going to use the following project: https://github.com/scottwis/OpenFileOrFolderDialog
However, I faced one problem. It uses the GetOpenFileName function and OPENFILENAME structure. And OPENFILENAME has the member named templateID. It's the identifier for dialog template. And the project contains the res1.rc file and the templated dialog init, too. But I couldn't figure out how to attach this file to my C# project.
Is there a better way to use an OpenFileDialog to select folders?

OpenFileDialog component opens the Windows dialog box for browsing and selecting files. To open and read the selected files, you can use the OpenFileDialog. OpenFile method, or create an instance of the System. IO.
To open a folder, you just specify folder name without /select, part. Something like explorer c:\folder_name . /select option requires an existing file or folder and open its parent and select the item. Thus both options are available.
Unlike other Windows Forms controls, a FolderBrowserDialog does not have or need visual properties like others. To create a FolderBrowserDialog control at design-time, you simply drag and drop a FolderBrowserDialog control from Toolbox to a Form in Visual Studio.
In this article, you'll learn how to use the OpenFileDialog in C#. C# OpenFileDialog control allows us to browse and select files on a computer in an application. A typical Open File Dialog looks like Figure 1 where you can see Windows Explorer like features to navigate through folders and select a file.
In VS .NET, when you are selecting a folder for a project, a dialog that looks like an OpenFileDialog or SaveFileDialog is displayed, but is set up to accept only folders. Ever since I've seen this I've wanted to know how it's done. I am aware of the FolderBrowserDialog, but I've never really liked that dialog.
It's got a lot of shell related stuff, including the CommonOpenFileDialog class (in the Microsoft.WindowsAPICodePack.Dialogs namespace). This is the perfect solution - the usual open dialog with only folders displayed. Unfortunately Microsoft no longer ships this package, but several people have unofficially uploaded binaries to NuGet.
Once the ShowDialog method is called, you can browse and select a file. After you place an OpenFileDialog control on a Form, the next step is to set properties. The easiest way to set properties is from the Properties Window. You can open Properties window by pressing F4 or right click on a control and select Properties menu item.
Basically you need the FolderBrowserDialog class:
Prompts the user to select a folder. This class cannot be inherited.
Example:
using(var fbd = new FolderBrowserDialog()) { DialogResult result = fbd.ShowDialog(); if (result == DialogResult.OK && !string.IsNullOrWhiteSpace(fbd.SelectedPath)) { string[] files = Directory.GetFiles(fbd.SelectedPath); System.Windows.Forms.MessageBox.Show("Files found: " + files.Length.ToString(), "Message"); } } If you work in WPF you have to add the reference to System.Windows.Forms.
you also have to add using System.IO for Directory class
