文件对话框WPF(5)----文件浏览对话框

2023-01-01 11:51:13

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）

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。
