## 二、打开文件 ##

private void chooseFileBtn_Click(object sender, EventArgs e)
    {
        
        OpenFileDialog openFileDialog = new OpenFileDialog();
        openFileDialog.Title = "请选择文件";
        //openFileDialog.Filter = "文本文件(*.txt)|*.txt|所有文件(*.*)|*.*";
        openFileDialog.FilterIndex = 1;
        openFileDialog.Multiselect = false;
        if (openFileDialog.ShowDialog() == DialogResult.OK)
        {
        
            label1.Text = openFileDialog.FileName;
        }
    }

## 三、打开文件夹 ##

private void chooseFilePathBtn_Click(object sender, EventArgs e)
    {
        
        FolderBrowserDialog folderBrowserDialog = new FolderBrowserDialog();
        folderBrowserDialog.Description = "请选择文件夹";
        if (folderBrowserDialog.ShowDialog() == DialogResult.OK)
        {
        
            label1.Text = folderBrowserDialog.SelectedPath;
        }
    }

## 四、获取当前文件目录 ##

private void Form1_Load(object sender, EventArgs e)
    {
        
        label1.Text = Environment.CurrentDirectory;
    }

## 五、源码工程 ##
