【1】直接用组件：不知道05有没有，反正08有。FolderBrowserDialog直接拖到winform中就可以。代码：

private void button2_Click(object sender, EventArgs e)
        {
            folderBrowserDialog1.Description = "请选择**文件夹";
            //folderBrowserDialog1.ShowNewFolderButton = true;
            //folderBrowserDialog1.RootFolder = Environment.SpecialFolder.Personal;           
            if (folderBrowserDialog1.ShowDialog()==DialogResult.OK)
            {
                MessageBox.Show(folderBrowserDialog1.SelectedPath);
            }
        }

【2】网络高人写的一个类，我以前一直用这个的，最近才发现有组件，哎。看看，首先要添加一个类，类中添加一个引用system.desing的dll.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

//添加
using System.Windows.Forms;
using System.Windows.Forms.Design;

namespace useByte
{
    class FolderDialog : FolderNameEditor
    {
        FolderNameEditor.FolderBrowser fDialog = new
             FolderNameEditor.FolderBrowser();
        //构造函数
        public FolderDialog()
        {

        }

        public DialogResult DisplayDialog()
        {
            return DisplayDialog("请选择一个文件夹");
        }

        public DialogResult DisplayDialog(string description)
        {
            fDialog.Description = description;
            return fDialog.ShowDialog();
        }

        public string Path
        {
            get
            {
                return fDialog.DirectoryPath;
            }
        }

        //析构函数
        ~FolderDialog()
        {
            fDialog.Dispose();
        }

    }
}

使用方法：简单不用多说。

FolderDialog fd = new FolderDialog();
            fd.DisplayDialog();
            MessageBox.Show(fd.Path);
