文件对话框WPF(5)----文件浏览对话框
废话就不多说了，开始。。。
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：
- 支撑Windows Shell命名空间对象，包含新的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）。
- 支撑WPF和Windows Forms的Windows 7资源管理器浏览器控件（Explorer Browser Control）。
- 支撑Shell的属性系统。
- 用于Windows 7任务栏Jumplists、Icon Overlay和Progress Bar的帮助程序。
- 支撑Windows Vista和Windows 7的通用文件对话框，并包含了自定义文件对话框控件。
- 支撑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：
<Window x:Class="WpfFileExploerDialog.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="148" Width="434" Background="#E609072F">
<Grid Name="Grid1">
<TextBox Height="25" Text = "{Binding Path=TextBoxValue}" HorizontalAlignment="Left" Margin="15,29,0,0" Name="textBoxFilePath" VerticalAlignment="Top" Width="347" />
<Button Content="..." Click="ButtonFileSelect" Height="24" HorizontalAlignment="Left" Margin="377,30,0,0" Name="buttonFileDialog" VerticalAlignment="Top" Width="25" />
</Grid>
</Window>
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
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
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;
}
}
}
}
5：程序运行结果如下：
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，例如上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
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
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;
}
}
}
}
文章结束给大家分享下程序员的一些笑话语录：
看新闻说中国输入法全球第一！领先了又如何？西方文字根本不需要输入法。一点可比性都没有。
