Visual Studio 中用代码打开文件目录

首先引用 命名空间： System.Windows.Forms;

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Windows.Forms;

using System.IO;

namespace OpenFile

{

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

}

private void button1_Click(object sender, EventArgs e)

{

Stream myStream = null;

OpenFileDialog openFileDialog1 = new OpenFileDialog();

openFileDialog1.InitialDirectory = "c:\\";

openFileDialog1.Filter = "Excel 文件t(*.xl*;*.xlsx;*.xlsm;*.xlsb;*.xlam;*.xltx;*.xltm;*.xls)|*.xl*;*.xlsx;*.xlsm;*.xlsb;*.xlam;*.xltx;*.xltm;*.xls|All files (*.*)|*.*";

openFileDialog1.FilterIndex = 2;

openFileDialog1.RestoreDirectory = true;

if (openFileDialog1.ShowDialog() == DialogResult.OK)

{

try

{

if ((myStream = openFileDialog1.OpenFile()) != null)

{

using (myStream)

{

// Insert code to read the stream here.

}

}

}

catch (Exception ex)

{

MessageBox.Show("Error: Could not read file from disk. Original error: " + ex.Message);

}

}

}

}

}
