使用OpenFileDialog作为目录,而不是FolderBrowserDialog

using System;
using System.IO;
using System.Windows.Forms;

namespace MyApplication
{
    public class MyClass
    {
        public void BrowseForFolder()
        {
            FolderBrowserDialog folderBrowserDialog = new FolderBrowserDialog();
            folderBrowserDialog.ShowNewFolderButton = true;
            DialogResult result = folderBrowserDialog.ShowDialog();
            if (result == DialogResult.OK)
            {
                string selectedPath = folderBrowserDialog.SelectedPath;
                // 在这里处理所选文件夹
            }
        }
    }
}
