WPF文件和文件夹的操作

1、对文件的操作

    private void button_chose_Click(object sender, RoutedEventArgs e)
    {
        var openFileDialog = new Microsoft.Win32.OpenFileDialog()
        {  
　　　　　　　　DefaultExt =".sql",
            Filter = "Excel Files (*.sql)|*.sql|All files(*.*)|*.*"
        };
        var result = openFileDialog.ShowDialog();
        if (result == true)
        {
            this.textblock_filename.Text = openFileDialog.FileName;
        }
    }  

2、文件夹的操作，选择文件夹对话框：WPF中似乎没有打开文件夹对话框，不过可以通过winform的方法打开，调研之前需要引用System.Windows.Forms;

private void button_runScript_Click(object sender, RoutedEventArgs e)
{
    FolderBrowserDialog m_Dialog = new FolderBrowserDialog();
    DialogResult result = m_Dialog.ShowDialog();  

    if (result == System.Windows.Forms.DialogResult.Cancel)
    {
        return;
    }
    string m_Dir = m_Dialog.SelectedPath.Trim();
    this.textblock_filename.Text = m_Dir;
}
