第493篇--OpenFolderDialog implementation

If you have developed a Windows Form project, you must haved experienced the OpenFileDialog class, but WinForm does not provided a class named OpenFolderDialog. Thus today, I'd like to share with your the implementation of OpenFolderDialog class as below.

First, you need to add the reference to System.Design.Dll.

Code snippet:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Windows.Forms.Design;

namespace WindowsFormsOpenFile
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            using (OpenFolderDialog openFolderDlg = new OpenFolderDialog())
            {
                if (openFolderDlg.ShowDialog() == DialogResult.OK)
                {
                    textBox1.Text = openFolderDlg.Path;
                }
            }
        }
    }

    public class OpenFolderDialog : FolderNameEditor, IDisposable
    {
        FolderNameEditor.FolderBrowser fDialog = new FolderNameEditor.FolderBrowser();

        public OpenFolderDialog()
        {
        }

        public DialogResult ShowDialog()
        {
            return ShowDialog("Select a folder:");
        }

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

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

        public void Dispose()
        {
            fDialog.Dispose();
        }
    }
}

                if (openFolderDlg.ShowDialog() == DialogResult.OK)
                {
                    textBox1.Text = openFolderDlg.Path;
                }
            }
        }

    public class OpenFolderDialog : FolderNameEditor, IDisposable

Save file dialogue:

 private void SaveButton_Click(object sender, EventArgs e)
        {
            SaveFileDialog saveFileDialog1 = new SaveFileDialog();
            saveFileDialog1.InitialDirectory = @"C:\";
            saveFileDialog1.Title = "Save text Files";
            saveFileDialog1.CheckFileExists = true;
            saveFileDialog1.CheckPathExists = true;
            saveFileDialog1.DefaultExt = "txt";
            saveFileDialog1.Filter = "Text files (*.txt)|*.txt|All files (*.*)|*.*";
            saveFileDialog1.FilterIndex = 2;
            saveFileDialog1.RestoreDirectory = true;
            if (saveFileDialog1.ShowDialog() == DialogResult.OK)
            {
                //textBox1.Text = saveFileDialog1.FileName;
            }
        }

Another version:
   private void SaveFileDialog()
        {
            //string localFilePath, fileNameExt, newFileName, FilePath;
            SaveFileDialog saveFileDialog1 = new SaveFileDialog();
            //设置文件类型
            saveFileDialog1.Filter = " txt files(*.txt)|*.txt|All files(*.*)|*.*";
            //设置默认文件类型显示顺序
            saveFileDialog1.FilterIndex = 2;
            //保存对话框是否记忆上次打开的目录
            saveFileDialog1.RestoreDirectory = true;
            //点了保存按钮进入
            if (saveFileDialog1.ShowDialog() == System.Windows.Forms.DialogResult.OK)
            {
                var res = saveFileDialog1.FileName;
                //获得文件路径
                //localFilePath = saveFileDialog1.FileName.ToString();
                //获取文件名，不带路径
                //fileNameExt = localFilePath.Substring(localFilePath.LastIndexOf("//") + 1);
                //获取文件路径，不带文件名
                //FilePath = localFilePath.Substring(0, localFilePath.LastIndexOf("//"));
                //给文件名前加上时间
                //newFileName = DateTime.Now.ToString("yyyyMMdd") + fileNameExt;
                //在文件名里加字符
                //saveFileDialog1.FileName.Insert(1,"dameng");
                //System.IO.FileStream fs = (System.IO.FileStream)saveFileDialog1.OpenFile();//输出文件
                //fs输出带文字或图片的文件，就看需求了
            }
        }
  /// <summary>
        /// Open File Dialog
        /// </summary>
        private void OpenFileDialog()
        {
            string path = string.Empty;
            using (OpenFileDialog ofd = new OpenFileDialog())
            {
                //定义打开的默认文件夹位置
                ofd.Filter = " txt files(*.txt)|*.txt|All files(*.*)|*.*";
                ofd.InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
                if (ofd.ShowDialog() == System.Windows.Forms.DialogResult.OK)
                {
                    path = ofd.FileName;
                }
            }
