Folder browser dialog like open file dialog

提问by Rockstart

Please see the snapshot below. This was taken from "New project creation" workflow in Visual Studio 2008.

请看下面的快照。这取自 Visual Studio 2008 中的“新建项目”工作流。

This window is used for selecting a folder in which the project will be stored. How do I create a similar window in my c# application?

此窗口用于选择将存储项目的文件夹。如何在我的 c# 应用程序中创建一个类似的窗口？

It is something similar in Office, a dialog which allows to select a folder. The only difference is that the Select folder button is named "OK" instead of "Select folder".

它与 Office 中的类似，一个允许选择文件夹的对话框。唯一的区别是“选择文件夹”按钮被命名为“确定”而不是“选择文件夹”。

Microsoft.Office.Interop.Excel.Application app = new Microsoft.Office.Interop.Excel.Application();
Microsoft.Office.Core.FileDialog fileDialog = app.get_FileDialog(Microsoft.Office.Core.MsoFileDialogType.msoFileDialogFolderPicker);
fileDialog.InitialFileName = "c:\Temp\"; //something you want
int nres = fileDialog.Show();
if (nres == -1) //ok
{
    Microsoft.Office.Core.FileDialogSelectedItems selectedItems = fileDialog.SelectedItems;

    string[] selectedFolders = selectedItems.Cast<string>().ToArray();

    if (selectedFolders.Length > 0)
    {
        string selectedFolder = selectedFolders[0];
    }
}

Of course, you need to add references to Microsoft.Office.Core (Microsoft Office 14.0 Object Library) and Microsoft.Office.Interop.Excel (Microsoft Excel 14.0 Object Library).

当然，您需要添加对 Microsoft.Office.Core（Microsoft Office 14.0 对象库）和 Microsoft.Office.Interop.Excel（Microsoft Excel 14.0 对象库）的引用。

I found a good article about the default FolderBrowserDialog and its limitations: http://www.ssware.com/articles/folderbrowserdialog-unmasked-everything-you-wanted-to-know-about-the-folder-browser-component-from-dotnet-framework.htm

There is a third party compoment "Shell MegaPack" (http://www.ssware.com/megapack.htm) from ssware which offers windows explorer like file and folder browser-controls for WinForms, ASP.net and WPF.

有一个来自 ssware 的第三方组件“Shell MegaPack”（http://www.ssware.com/megapack.htm），它为 WinForms、ASP.net 和 WPF 提供了像文件和文件夹浏览器控件这样的 Windows 资源管理器。

I modified the code from C# to VB, and my env is VS2015 + Office 2010. My code is slightly different than Daniel's, as some function from Daniel's code supports to only Office 2003/2007

我把代码从C#改成VB，我的环境是VS2015+Office 2010。我的代码和Daniel的略有不同，因为Daniel代码中的一些功能只支持Office 2003/2007

By using a new excel instance, it will be slower than just opening a OpenFileDialog or OpenFolderDialog, but is it way more user friendly. My program is only calling this code once, so trading off the performance for user-friendliness is not a concern in my case.

通过使用新的 excel 实例，它会比打开 OpenFileDialog 或 OpenFolderDialog 慢，但它是否更用户友好。我的程序只调用此代码一次，因此在我的情况下，为了用户友好性而牺牲性能并不是一个问题。

Imports Microsoft.Office
Imports Excel = Microsoft.Office.Interop.Excel

Private Sub Button_select_raw_dir_Click(sender As Object, e As EventArgs) Handles Button_select_raw_dir.Click
    Dim raw_app As Excel.Application = New Excel.Application
    Dim raw_data_open_folder_dialog As Microsoft.Office.Core.FileDialog
    raw_data_open_folder_dialog = raw_app.FileDialog(Microsoft.Office.Core.MsoFileDialogType.msoFileDialogFolderPicker)
    raw_data_open_folder_dialog.AllowMultiSelect = False
    raw_data_open_folder_dialog.Title = "Please select the raw data's dir "
    Dim nres As Integer = raw_data_open_folder_dialog.Show()
    Dim sz_SelectedPath As String = Nothing
    If nres = -1 Then '-1 means open... lol
        For Each selectedItems As Object In raw_data_open_folder_dialog.SelectedItems
            sz_SelectedPath = selectedItems.ToString()
        Next
        TextBox_raw_data_dir.Text = sz_SelectedPath
    End If

    raw_app.Quit()
    ReleaseComObject(raw_app)
    GC.Collect()
    GC.WaitForPendingFinalizers()
End Sub

' Release excel objects to avoid memory leak
Public Sub ReleaseComObject(ByRef obj As Object)
    Try
        System.Runtime.InteropServices.Marshal.ReleaseComObject(obj)
        obj = Nothing
    Catch ex As Exception
        obj = Nothing
        MsgBox("Exception! Failed to release com obj, debug your code.")
    End Try
End Sub

If you want a C# version, I believe you are smart enough to port it to C# :)

如果你想要一个 C# 版本，我相信你足够聪明，可以将它移植到 C# :)

If you are ok with adding a nuget package, Microsoft.WindowsAPICodePack.Shell has a CommonOpenFileDialogthat can be used in "folder mode" which should match your desired usage.

如果您可以添加 nuget 包，Microsoft.WindowsAPICodePack.Shell 有一个CommonOpenFileDialog可以在“文件夹模式”中使用的程序包，它应该符合您所需的用法。

var directoryDialog = new CommonOpenFileDialog
  {
     IsFolderPicker = true,
     Title = "Select Folder"
  };

Kindly check out BetterFolderBrowser. It provides just what you need and so much more.

请查看BetterFolderBrowser。它提供了您所需要的以及更多。

BetterFolderBrowseris a .NET component library that was written to help developers provide a better folder-browsing and selection experience to users by employing a similar browser dialog as the standard OpenFileDialogin place of the current FolderBrowserDialogwhich only allows for single-folder selections with its tree-view display format. This allows for a much easier viewing, modification, searching and selection experience using the standard Windows Explorer dialog.

BetterFolderBrowser是一个 .NET 组件库，旨在帮助开发人员通过使用与标准OpenFileDialog类似的浏览器对话框代替当前的FolderBrowserDialog来帮助开发人员为用户提供更好的文件夹浏览和选择体验，后者只允许使用其树视图显示格式。这允许使用标准的 Windows 资源管理器对话框更轻松地查看、修改、搜索和选择体验。
