如何使用OpenFileDialog来选择文件夹?

How to use OpenFileDialog to select folders?

我打算使用以下项目:https://github.com/scottwis/OpenFileOrFolderDialog

但是，我遇到了一个问题.它使用GetOpenFileName 函数和OPENFILENAME 结构.而OPENFILENAME 有名为templateID 的成员.它是对话框模板的标识符.并且该项目还包含 res1.rc 文件和模板化对话框初始化.但我不知道如何将此文件附加到我的 C# 项目中.

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.

有没有更好的方法来使用 OpenFileDialog 来选择文件夹?

Is there a better way to use an OpenFileDialog to select folders?

推荐答案

基本上你需要 FolderBrowserDialog 类:

提示用户选择一个文件夹.这个类不能被继承.

Prompts the user to select a folder. This class cannot be inherited.

示例:

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");
    }
}

如果您在 WPF 中工作，则必须添加对 System.Windows.Forms 的引用.

If you work in WPF you have to add the reference to System.Windows.Forms.

您还必须为Directory 类添加using System.IO
