WinForm打开一个文件夹（得到文件夹路径 2种方法）

方法一：

Form窗体拖一个FolderBrowserDialog控件 在按钮事件中写入以下代码：

//打开选择文件夹目录
        private void btnOpen_Click(object sender, EventArgs e)
        {

            folderBrowserDialog1.RootFolder = Environment.SpecialFolder.Desktop;
            folderBrowserDialog1.Description = "请选择文件夹";
            DialogResult d = folderBrowserDialog1.ShowDialog();
            if (d == DialogResult.OK)
            {

                //txtFilesName指的是界面一个文本框获取路径
                txtFilesName.Text = folderBrowserDialog1.SelectedPath;
            }
            else
                txtFilesName.Text = "请选择目录！";
        }

        private void btnEXC_Click(object sender, EventArgs e)
        {
            Application.Exit();
        }

方法二：

新建一个类名字为FolderDialog.cs代码如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Forms.Design;
using System.Windows.Forms;

namespace Read
{
    public class FolderDialog:FolderNameEditor
    {
        FolderNameEditor.FolderBrowser fDialog = new System.Windows.Forms.Design.FolderNameEditor.FolderBrowser();
        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;
            }
        }
        ~FolderDialog()
        {
            fDialog.Dispose();
        }

    }
} 

在窗体的后台事件调用：

//打开选择文件夹目录
        private void btnOpen_Click(object sender, EventArgs e)
        {
            FolderDialog openFolder = new FolderDialog();
            if (openFolder.DisplayDialog() == DialogResult.OK)
            {
                txtFilesName.Text = openFolder.Path.ToString();
            }
            else
                txtFilesName.Text = "请选择目录！";
