WPF中文件浏览对话框的实现可以利用Windows API Code Pack,它是一个用于访问Windows Vista/7 特性的托管代码函数库,但并没有包含在.NET 4.0中。
该代码包的特性如下所示:
- 支持Windows Shell命名空间对象,包括新的Windows 7资源库(Libraries)、固定名称文件夹和非文件系统容器。
- Windows Vista和Windows 7任务对话框(Task Dialogs)。
- 支持WPF和Windows Forms的Windows 7资源管理器浏览器控件(Explorer Browser Control)。
- 支持Shell的属性系统。
- 用于Windows 7任务栏Jumplists、Icon Overlay和Progress Bar的帮助程序。
- 支持Windows Vista和Windows 7的通用文件对话框,并包括了自定义文件对话框控件。
- 支持Direct3D 11.0和DXGI 1.0/1.1的API。
- 传感器平台(Sensor Platform)API
- 扩展的语言服务(Extended Linguistic Services)API。
1:代码包下载之后,解压,将其中的Microsoft.WindowsAPICodePack.dll 和Microsoft.WindowsAPICodePack.Shell.dll拷贝至工程中。然后Reference-->Add将其添加至Project中的References。
2:代码编写时,将其导入命名空间:
using Microsoft.WindowsAPICodePack.Shell;
using Microsoft.WindowsAPICodePack.Dialogs;
3:前台xmal代码如下:
4:后台xmal.cs代码如下:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
using System.ComponentModel;
using Microsoft.WindowsAPICodePack.Shell;
using Microsoft.WindowsAPICodePack.Dialogs;
namespace WpfFileExploerDialog
{
///
/// Interaction logic for MainWindow.xaml
///
public partial class MainWindow : Window, INotifyPropertyChanged
{
public MainWindow()
{
InitializeComponent();
Grid1.DataContext = this;
}
public event PropertyChangedEventHandler PropertyChanged;
protected void NotifyPropertyChanged(string property)
{
if (PropertyChanged != null)
{
PropertyChanged(this, new PropertyChangedEventArgs(property));
}
}
private string _Value2;
public string TextBoxValue
{
get { return _Value2; }
set
{
if (value != _Value2)
{
_Value2 = value;
NotifyPropertyChanged("TextBoxValue");
}
}
}
private void ButtonFileSelect(object sender, RoutedEventArgs e)
{
ShellContainer selectedFolder = null;
selectedFolder = KnownFolders.Computer as ShellContainer;
CommonOpenFileDialog commonOpenFileDialog = new CommonOpenFileDialog();
commonOpenFileDialog.InitialDirectoryShellContainer = selectedFolder;
commonOpenFileDialog.EnsureReadOnly = true;
if (commonOpenFileDialog.ShowDialog() == CommonFileDialogResult.Ok)
{
TextBoxValue = commonOpenFileDialog.FileName;
}
}
}
}
另外,还可以将文件浏览窗口直接定位到固定的文件夹,并且添加想要的文件过滤器,例如下面的代码就是将其定位到SampleVideos文件夹:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
using System.ComponentModel;
using Microsoft.WindowsAPICodePack.Shell;
using Microsoft.WindowsAPICodePack.Dialogs;
namespace WpfFileExploerDialog
{
///
/// Interaction logic for MainWindow.xaml
///
public partial class MainWindow : Window, INotifyPropertyChanged
{
public MainWindow()
{
InitializeComponent();
Grid1.DataContext = this;
}
public event PropertyChangedEventHandler PropertyChanged;
protected void NotifyPropertyChanged(string property)
{
if (PropertyChanged != null)
{
PropertyChanged(this, new PropertyChangedEventArgs(property));
}
}
private string _Value2;
public string TextBoxValue
{
get { return _Value2; }
set
{
if (value != _Value2)
{
_Value2 = value;
NotifyPropertyChanged("TextBoxValue");
}
}
}
private void ButtonFileSelect(object sender, RoutedEventArgs e)
{
ShellContainer selectedFolder = null;
//文件夹定位至SampleVideos
selectedFolder = KnownFolders.SampleVideos as ShellContainer;
CommonOpenFileDialog commonOpenFileDialog = new CommonOpenFileDialog();
commonOpenFileDialog.InitialDirectoryShellContainer = selectedFolder;
commonOpenFileDialog.EnsureReadOnly = true;
//设置文件过滤
commonOpenFileDialog.Filters.Add(new CommonFileDialogFilter("WMV Files", "*.wmv"));
commonOpenFileDialog.Filters.Add(new CommonFileDialogFilter("AVI Files", "*.avi"));
commonOpenFileDialog.Filters.Add(new CommonFileDialogFilter("MP3 Files", "*.mp3"));
commonOpenFileDialog.Filters.Add(new CommonFileDialogFilter("MKV Files", "*.mkv"));
if (commonOpenFileDialog.ShowDialog() == CommonFileDialogResult.Ok)
{
TextBoxValue = commonOpenFileDialog.FileName;
}
}
}
}
