OpenFileDialog open = new OpenFileDialog(); //创建一个打开对话框
             open.AddExtension = true; //设置是否自动在文件中添加扩展名
            open.CheckFileExists = true; //检查文件
            open.Filter = "MP3文件 (*.mp3)|*.mp3|所有文件 (*.*)|*.*"; //设置要打开的类型为mp3和任意文件
           //string a="";
            if (open.ShowDialog() == DialogResult.OK) //如果用户点击了“确定”
            {}

openFileDialog1.FileName来获取打开文件的全路径。

读取多个文件

看下面的代码，已经测试通过：this.openFileDialog1.Multiselect = true;this.openFileDialog1.ShowDialog(); foreach(string fName in this.openFileDialog1.FileNames){ this.listBox1.Items.Add(fName);}

一次导入文件夹中的所有文件

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 NoteBook{ public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void button1_Click(object sender, EventArgs e) { OpenFileDialog ofd = new OpenFileDialog(); if (ofd.ShowDialog() == DialogResult.OK) { StreamReader sr = new StreamReader(ofd.FileName); textBox1.Text = sr.ReadToEnd(); sr.Close(); } }}
