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。
