一共两个页面，第一个为MainPage.xaml，代码如下：
<!--ContentPanel - place additional content here-->
<Grid x:Name="ContentPanel" Grid.Row="" Margin="12,0,12,0">
<Image Name="PhotoImage" Height="" HorizontalAlignment="Left" Margin="9,6,0,0" Stretch="Fill" VerticalAlignment="Top" Width=""/>
<Button Name="SaveButton" Click="SaveButton_Click" Content="保存" Height="" HorizontalAlignment="Left" Margin="7,482,0,0" VerticalAlignment="Top" Width="">
<Button.Background>
<LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
<GradientStop Color="Black" Offset=""/>
<GradientStop Color="#FFEB1818" Offset=""/>
</LinearGradientBrush>
</Button.Background>
</Button>
<TextBlock Height="" HorizontalAlignment="Left" Margin="27,442,0,0" Name="textBlock1" Text="输入照片名：" FontSize="" VerticalAlignment="Top"/>
<TextBox Name="PhotoName" Height="" HorizontalAlignment="Left" Margin="165,424,0,0" Text="" VerticalAlignment="Top" Width="">
<TextBox.Background>
<LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
<GradientStop Color="Black" Offset=""/>
<GradientStop Color="#FFD01818" Offset=""/>
</LinearGradientBrush>
</TextBox.Background>
</TextBox>
<Button Name="TakePhotoButton" Click="TakePhotoButton_Click" Content="拍照" Height="" Margin="9,366,8,0" VerticalAlignment="Top">
<Button.Background>
<LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
<GradientStop Color="Black" Offset=""/>
<GradientStop Color="#FFD61212" Offset=""/>
</LinearGradientBrush>
</Button.Background>
</Button>
</Grid>
</Grid>
<!--Sample code showing usage of ApplicationBar-->
<phone:PhoneApplicationPage.ApplicationBar>
<shell:ApplicationBar IsVisible="True" IsMenuEnabled="True">
<shell:ApplicationBarIconButton IconUri="/Images/appbar.feature.search.rest.png" Text="查看" Click="ApplicationBarIconButton_Click"/>
</shell:ApplicationBar>
</phone:PhoneApplicationPage.ApplicationBar>
前台
后台代码如下：
MainPage.xaml.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using Microsoft.Phone.Controls;
using Microsoft.Phone.Tasks;
using Microsoft.Phone;
using System.IO;
using System.IO.IsolatedStorage;
namespace 在隔离存储中存取照片
{
public partial class MainPage : PhoneApplicationPage
{
// Constructor
string filename;
byte[] _imageAsByte;
public MainPage()
{
InitializeComponent();
}
private void SaveButton_Click(object sender, RoutedEventArgs e)
{
filename = PhotoName.Text;
if (filename != ""&&PhotoImage.Source!=null)
{
using (var store = IsolatedStorageFile.GetUserStoreForApplication())
{
if (!store.FileExists(filename) || store.FileExists(filename) && MessageBox.Show("Overwrite the file?", "Question", MessageBoxButton.OKCancel) == MessageBoxResult.OK)
{
using (var stream = store.CreateFile(filename))
{
stream.Write(_imageAsByte, , _imageAsByte.Length);
}
PhotoImage.Source = null;
PhotoName.Text = "";
NavigationService.Navigate(new Uri("/Page1.xaml", UriKind.Relative));
}
}
}
else
{
MessageBox.Show("Sorry,but you must take a photo and write the photo's name in the textbox!","Warning!",MessageBoxButton.OK);
}
}
private void TakePhotoButton_Click(object sender, RoutedEventArgs e)
{
CameraCaptureTask task = new CameraCaptureTask();
task.Completed += new EventHandler<PhotoResult>(task_Completed);
task.Show();
}
void task_Completed(object sender, PhotoResult e)
{
if (e.TaskResult == TaskResult.OK)
{
_imageAsByte = new byte[e.ChosenPhoto.Length];
e.ChosenPhoto.Read(_imageAsByte, , _imageAsByte.Length);
e.ChosenPhoto.Seek(, SeekOrigin.Begin);
this.PhotoImage.Source = PictureDecoder.DecodeJpeg(e.ChosenPhoto);
}
}
private void ApplicationBarIconButton_Click(object sender, EventArgs e)
{
NavigationService.Navigate(new Uri("/Page1.xaml",UriKind.Relative));
}
}
}
效果如图所示：
同时还新建了一个照片文件的类，从IsolatedStorage里读取出照片及照片名再绑定到Page1.xaml中的ListBox中。类代码如下：
PhotoFile.cs
using System;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Ink;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
namespace 在隔离存储中存取照片
{
public class PhotoFile
{
public ImageSource Image { get; set; }
public string ImageName { get; set; }
}
}
第二个Page1.xaml，代码如下：
<!--ContentPanel - place additional content here-->
<Grid x:Name="ContentPanel" Grid.Row="" Margin="12,0,12,0">
<ListBox Height="" HorizontalAlignment="Left" Margin="6,6,0,0" Name="listBox1" VerticalAlignment="Top" Width="">
<ListBox.ItemTemplate>
<DataTemplate>
<Grid Margin="{StaticResource PhoneTouchTargetOverhang}">
<StackPanel Orientation="Horizontal">
<Image Source="{Binding Image}" Width="" Height="" Stretch="Fill"/>
<TextBlock Text="{Binding ImageName}" Foreground="Coral" FontSize="" TextWrapping="Wrap" Width=""/>
</StackPanel>
</Grid>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</Grid>
</Grid>
<!--Sample code showing usage of ApplicationBar-->
<phone:PhoneApplicationPage.ApplicationBar>
<shell:ApplicationBar IsVisible="True" IsMenuEnabled="True">
<shell:ApplicationBarIconButton IconUri="/Images/appbar.add.rest.png" Text="添加" Click="ApplicationBarIconButton_Click"/>
</shell:ApplicationBar>
</phone:PhoneApplicationPage.ApplicationBar>
后台代码：
Page1.xaml.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using Microsoft.Phone.Controls;
using System.IO;
using System.IO.IsolatedStorage;
using System.Windows.Media.Imaging;
namespace 在隔离存储中存取照片
{
public partial class Page1 : PhoneApplicationPage
{
IsolatedStorageFile file = IsolatedStorageFile.GetUserStoreForApplication();
public Page1()
{
InitializeComponent();
}
protected override void OnNavigatedTo(NavigationEventArgs e)
{
List<PhotoFile> filelist = new List<PhotoFile>();
if (file.GetFileNames() != null)
{
foreach (string filename in file.GetFileNames())
{
PhotoFile photo = new PhotoFile();
BitmapImage bmp = new BitmapImage();
using (IsolatedStorageFileStream filestream = file.OpenFile(filename, FileMode.Open, FileAccess.ReadWrite))
{
bmp.SetSource(filestream);
filestream.Flush();
filestream.Close();
photo.Image = bmp;
photo.ImageName = " 照片名："+filename;
}
filelist.Add(photo);
}
listBox1.ItemsSource = filelist;
}
}
private void ApplicationBarIconButton_Click(object sender, EventArgs e)
{
NavigationService.Navigate(new Uri("/MainPage.xaml",UriKind.Relative));
}
}
}
运行效果如下：
