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

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();
}
}
}
