WPF文件和文件夾的操作

 

1、對文件的操作

    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、文件夾的操作，選擇文件夾對話框：WPF中似乎沒有打開文件夾對話框，不過可以通過winform的方法打開，調研之前需要引用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;  
}
