winform 实现选择文件和选择文件夹对话框的简单实例

实例如下:

//选择文件,点击【浏览】,选择文件 
private void button1_Click(object sender, EventArgs e) 
{ 
  OpenFileDialog openFileDialog1 = new OpenFileDialog();   //显示选择文件对话框 
  openFileDialog1.InitialDirectory = "c:\\"; 
  openFileDialog1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*"; 
  openFileDialog1.FilterIndex = 2; 
  openFileDialog1.RestoreDirectory = true; 
 
  if (openFileDialog1.ShowDialog() == DialogResult.OK) 
  { 
    this.textBox1.Text = openFileDialog1.FileName;     //显示文件路径 
  } 
} 
 
  
 
//选择文件夹:点击【浏览】,选择文件夹 
private void button4_Click(object sender, EventArgs e) 
{ 
  if (this.folderBrowserDialog1.ShowDialog() == DialogResult.OK) 
  { 
    if (this.folderBrowserDialog1.SelectedPath.Trim() != "") 
      this.textBox4.Text = this.folderBrowserDialog1.SelectedPath.Trim(); 
  } 
}

选择文件夹对话框,如果想默认一个文件夹,在click事件一开始添加以下代码:

folderBrowserDialog1.SelectedPath =“d:\”; 

呵呵,是不是很简单呢。
