如何使用
OpenFileDialog
选择文件夹？
我打算使用以下项目： https://github.com/scottwis/OpenFileOrFolderDialog
然而，我面临着一个问题。它使用了
GetOpenFileName
函数和
OPENFILENAME
结构。
OPENFILENAME
有一个名为
templateID
的成员。它是对话框模板的标识符。该项目还包含
res1.rc
文件和模板化对话框初始化。但是我不知道如何将这个文件附加到我的C#项目中。
有没有更好的方式使用
OpenFileDialog
来选择文件夹？

听起来你只是在找 FolderBrowserDialog

奇怪的是，这么多答案/投票，但没有人添加以下代码作为答案：
using (var opnDlg = new OpenFileDialog()) //ANY dialog
//opnDlg.Filter = "Png Files (*.png)|*.png";
//opnDlg.Filter = "Excel Files (*.xls, *.xlsx)|*.xls;*.xlsx|CSV Files (*.csv)|*.csv"
if (opnDlg.ShowDialog() == DialogResult.OK)
//opnDlg.SelectedPath -- your result
}

为了提醒那些想要避免使用
FolderBrowserDialog
的用户，微软曾经发布了一个名为WindowsAPICodePack的应用程序接口，它有一个名为
CommonOpenFileDialog
的有用的对话框，可以设置为
IsFolderPicker
模式。该应用程序接口可从微软以
NuGet package
形式获得。
这就是我安装和使用
CommonOpenFileDialog
所需的全部内容。(NuGet处理了依赖项)
Install-Package Microsoft.WindowsAPICodePack-Shell对于include行：
using Microsoft.WindowsAPICodePack.Dialogs;用法：
CommonOpenFileDialog dialog = new CommonOpenFileDialog();
dialog.InitialDirectory = "C:\\Users";
dialog.IsFolderPicker = true;
if (dialog.ShowDialog() == CommonFileDialogResult.Ok)
MessageBox.Show("You selected: " + dialog.FileName);
}

有一种使用
OpenFileDialog
的黑客解决方案，其中
ValidateNames
和
CheckFileExists
都被设置为false，并为
FileName
提供了一个模拟值，以指示选择了一个目录。
我之所以说hack，是因为它让用户对如何选择文件夹感到困惑。它们需要在所需的文件夹中，然后只需在文件名显示"Folder Selection“时按Open。
这是基于Denis Stankovski的 Select file or folder from the same dialog 。
OpenFileDialog folderBrowser = new OpenFileDialog();
// Set validate names and check file exists to false otherwise windows will
// not let you select "Folder Selection."
folderBrowser.ValidateNames = false;
folderBrowser.CheckFileExists = false;
folderBrowser.CheckPathExists = true;
// Always default to Folder Selection.
folderBrowser.FileName = "Folder Selection.";
if (folderBrowser.ShowDialog() == DialogResult.OK)
string folderPath = Path.GetDirectoryName(folderBrowser.FileName);
// ...
}

这应该是最明显和最直接的方法
using (var dialog = new System.Windows.Forms.FolderBrowserDialog())
System.Windows.Forms.DialogResult result = dialog.ShowDialog();
if(result == System.Windows.Forms.DialogResult.OK)
selectedFolder = dialog.SelectedPath;
}

这是一个纯C#版本，不含nuget，适用于所有版本的.NET (包括.NET核心、.NET 5、WPF、Winforms等)。并使用Windows Vista (和更高版本)的 FOS_PICKFOLDERS 选项的 IFileDialog 界面，所以它有很好的文件夹选择器Windows标准UI。
我还添加了WPF的
Window
类型支持，但这是可选的，可以只删除WPF标记的行。
用法：
var dlg = new FolderPicker();
dlg.InputPath = @"c:\windows\system32";
if (dlg.ShowDialog() == true)
MessageBox.Show(dlg.ResultPath);
}代码：
using System;
using System.Diagnostics;
using System.Runtime.InteropServices;
using System.Runtime.InteropServices.ComTypes;
using System.Windows; // for WPF support
using System.Windows.Interop; // for WPF support
public class FolderPicker

public virtual string ResultName { get; protected set; }
public virtual string InputPath { get; set; }
public virtual bool ForceFileSystem { get; set; }
public virtual string Title { get; set; }
public virtual string OkButtonLabel { get; set; }

dialog.SetFolder(item);
var options = FOS.FOS_PICKFOLDERS;
