WPF 选择文件和文件夹对话框。

选择文件对话框：

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

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;

代码：

        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;
        }

全部代码：

using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Forms;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;

{
    /// 

    /// MainWindow.xaml 的交互逻辑
    /// 
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }

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

        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;
        }
    }
}
