关于OpenFileDialog的使用

为了方便同事在日常工作中很快速生成大量数据, 我做了文件拷贝的小工具:
其中用到了OpenFileDialog这个类,下面是关于这个类的一些用法!
OpenFileDialog类是用来选择文件位置的,
FolderBrowserDialog 类用来选择文件夹位置.
具体代码如下:

程序源码:
using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Text;

using System.Windows.Forms;

using System.IO;
namespace copyFile

{

    public partial class Form1 : Form

    {

        String fileName;

        String folderName;

        String extendedName;

        String fileName1;

        

        public Form1()

        {

            InitializeComponent();

        }
        private void browse_Click(object sender,EventArgs e)

        {

            OpenFileDialog ofd = new OpenFileDialog();                //new一个方法

            ofd.InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);  //定义打开的默认文件夹位置

            ofd.ShowDialog();          //显示打开文件的窗口

             fileName = ofd.FileName;               //获得选择的文件路径

             textBox1.Text = fileName;

             extendedName = Path.GetExtension(fileName);       //获得文件扩展名

             fileName1 = Path.GetFileName(fileName);           //获得文件名

        }
        private void folder_Click(object sender, EventArgs e)

        {

            FolderBrowserDialog fbd = new FolderBrowserDialog();

            fbd.ShowDialog();

            folderName = fbd.SelectedPath;                     //获得选择的文件夹路径

            textBox3.Text = folderName;

        }
        private void ok_Click(object sender, EventArgs e)

        {

            if (textBox1.Text.Trim().Length == 0)

            {

                MessageBox.Show("文件路径不能为空!");

                return;

            }

            if (textBox2.Text.Trim().Length == 0)

            {

                MessageBox.Show("复制数量不能为空!");

                return;

            }

            if (textBox3.Text.Trim().Length == 0)

            {

                MessageBox.Show("目标文件夹路径不能为空!");

                return;

            }

            String newFile;                   //定义存储的位置,和存储的名称

            

            for (int i = 1; i <= Convert.ToInt32(textBox2.Text); i++)                   //从textBox2中获取要复制的次数

            {

                newFile = folderName + "\\" + fileName1 +"_"+ i.ToString() + extendedName;

;       File.Copy(fileName, newFile, true);            //使用Copy复制文件, Copy(源文件位置,目标文件夹位置,是否可以覆盖同名文件)

            }

            MessageBox.Show("复制完成!");

        }

    }

}
 
补充:
//获取文件名 

Path.GetFileName(OpenFileDialog.FileName) 

//获取文件路径 

Path.GetDirectoryName(OpenFileDialog.FileName) 

//获取文件扩展名 

Path.GetExtension(OpenFileDialog.FileName)
