c# - 以编程方式在 "This PC"文件夹下添加自定义文件夹

Question

有没有办法在此 PC 的“文件夹”下以编程方式添加文件夹？

预添加的文件夹是:

Desktop, Documents, Downloads, Music, Pictures and Videos

我想在安装我的应用程序时添加自定义文件夹。

Answer 1

您需要使用注册表。使用 GUID 添加该文件夹的注册表项
使用以下代码执行此操作，此代码在 x64 操作系统(Windows 8 及更高版本)和 x64 Build 上进行了测试。您需要下载Windows API并以管理员身份添加引用和运行应用程序以编写注册表项。

    private void btnAddCustomFolder_Click(object sender, EventArgs e)
    {
        var folderBrowserDialog1 = new FolderBrowserDialog();
        if (folderBrowserDialog1.ShowDialog(this) != DialogResult.OK) return;
        string cLSID = string.Format("{{{0}}}", Guid.NewGuid());
        string subkey = @"CLSID\" + cLSID;
        string folder = folderBrowserDialog1.SelectedPath;
