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;
}
}
}
}
    每日一道理
如果说生命是一座庄严的城堡,如果说生命是一株苍茂的大树,如果说生命是一只飞翔的海鸟。那么,信念就是那穹顶的梁柱,就是那深扎的树根,就是那扇动的翅膀。没有信念,生命的动力便荡然无存;没有信念,生命的美丽便杳然西去。(划线处可以换其他词语)

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。
