如何在所选文件夹中打开FolderBrowserDialog？

using System;
using System.Windows.Forms;

namespace YourNamespace
{
    public partial class YourForm : Form
    {
        public YourForm()
        {
            InitializeComponent();
        }

        private void buttonBrowse_Click(object sender, EventArgs e)
        {
            FolderBrowserDialog folderBrowserDialog = new FolderBrowserDialog();
            folderBrowserDialog.ShowDialog();
        }
    }
}

private void buttonBrowse_Click(object sender, EventArgs e)
{
    FolderBrowserDialog folderBrowserDialog = new FolderBrowserDialog();
    DialogResult result = folderBrowserDialog.ShowDialog();

    if (result == DialogResult.OK)
    {
        string selectedPath = folderBrowserDialog.SelectedPath;
        // 在这里处理所选文件夹
    }
}
