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。
