在Windows 8中我們的粘貼板分別保存4種信息：文本、圖片、網(wǎng)頁、文件。在本文中我們將分別復(fù)制和粘貼這4種元素，當(dāng)然你也可以在外部復(fù)制這4種元素，然后在程序中粘貼出來。

　　DataPackage：包含用戶希望與另一個(gè)應(yīng)用程序交換的數(shù)據(jù)

          //設(shè)置一個(gè)中轉(zhuǎn)變量保存用戶的值
       DataPackage dp = new DataPackage();

　　第一：我們來看看復(fù)制和粘貼文本的后臺(tái)處理代碼。

        //<!--復(fù)制文本-->
        private void CopyText_Click(object sender, RoutedEventArgs e)
        {
            dp.SetText(this.SourceText.Text);
            Clipboard.SetContent(dp);
        }
        //<!--粘貼文本-->
        private async void PasteText_Click(object sender, RoutedEventArgs e)
        {
            var ClipBoardData = Clipboard.GetContent();
            if (ClipBoardData.Contains(StandardDataFormats.Text))
            {
                this.TargetText.Text = await ClipBoardData.GetTextAsync();
            }
        }

　　第二：復(fù)制和粘貼圖片后臺(tái)處理代碼

        //<!--復(fù)制圖片-->
        private async void CopyImage_Click(object sender, RoutedEventArgs e)
        {
            Uri uri = new Uri("ms-appx:///Assets/iphone0426_006.jpg");
            StorageFile file = await StorageFile.GetFileFromApplicationUriAsync(uri);
            dp.SetBitmap(RandomAccessStreamReference.CreateFromFile(file));
            Clipboard.SetContent(dp);
        }
        //<!--粘貼圖片-->
        private async void PasteImage_Click(object sender, RoutedEventArgs e)
        {
            var ClipBoardData = Clipboard.GetContent();
            if (ClipBoardData.Contains(StandardDataFormats.Bitmap))
            {
                RandomAccessStreamReference img = await ClipBoardData.GetBitmapAsync();
                var imgstream = await img.OpenReadAsync();
                BitmapImage bitmap = new BitmapImage();
                bitmap.SetSource(imgstream);
                this.TargetImage.Source = bitmap;
            }
        }

　　第三：復(fù)制和粘貼HTML的后臺(tái)處理代碼

        //<!--復(fù)制HTML-->
        private void CopyHtml_Click(object sender, RoutedEventArgs e)
        {
            string html = HtmlFormatHelper.CreateHtmlFormat(this.SourceHtml.InvokeScript("eval", 
                new string[] { "document.documentElement.outerHTML;" }));
            dp.SetHtmlFormat(html);
            Clipboard.SetContent(dp);
        }
        //<!--粘貼HTML-->
        private async void PasteHtml_Click(object sender, RoutedEventArgs e)
        {
            var ClipBoardData = Clipboard.GetContent();
            if (ClipBoardData.Contains(StandardDataFormats.Html))
            {
                string html = await ClipBoardData.GetHtmlFormatAsync();
                this.TargetHtml.NavigateToString(html);
            }
        }

　　第四：復(fù)制和粘貼文件的后臺(tái)處理代碼

        //<!--復(fù)制文件-->
        private async void CopyFile_Click(object sender, RoutedEventArgs e)
        {
            Uri uri1 = new Uri("ms-appx:///Assets/iphone0426_006.jpg");
            StorageFile file1 = await StorageFile.GetFileFromApplicationUriAsync(uri1);
            Uri uri2 = new Uri("ms-appx:///Assets/iphone0426_010.jpg");
            StorageFile file2 = await StorageFile.GetFileFromApplicationUriAsync(uri2);
            List<StorageFile> filelist = new List<StorageFile>();
            filelist.Add(file1);
            filelist.Add(file2);
            dp.SetStorageItems(filelist);
            Clipboard.SetContent(dp);
        }
        //<!--粘貼文件-->
        private async void PasteFile_Click(object sender, RoutedEventArgs e)
        {
            var ClipBoardData = Clipboard.GetContent();
            this.TargetFile.Text = "";
            if (ClipBoardData.Contains(StandardDataFormats.StorageItems))
            {
                var filelist = await ClipBoardData.GetStorageItemsAsync();
                foreach (StorageFile sfile in filelist)
                {
                    StorageFile storageFileCopy = await sfile.CopyAsync(KnownFolders.DocumentsLibrary, 
                        sfile.Name,NameCollisionOption.ReplaceExisting);
                    this.TargetFile.Text += sfile.Name + "文件粘貼一份到“庫\\文檔\\" + sfile.Name+"\r";
                }
            }
        }

　　第五：我們貼出前臺(tái)代碼如下

    <Grid Background="{StaticResource ApplicationPageBackgroundThemeBrush}">
        <!--復(fù)制文本-->
        <TextBox  x:Name="SourceText" HorizontalAlignment="Left" Margin="96,50,0,0"

        <Image x:Name="TargetImage" HorizontalAlignment="Left" Margin="690,150,0,0"
               VerticalAlignment="Top"  Width="170" Height="170"/>
        <!--復(fù)制HTML-->
        <WebView x:Name="SourceHtml" HorizontalAlignment="Left" Source="http://wap.easou.com/"

        <Button x:Name="PasteHtml" Content="粘貼HTML" HorizontalAlignment="Left" 
                Margin="545,350,0,0" VerticalAlignment="Top" Click="PasteHtml_Click"/>
        <WebView x:Name="TargetHtml" HorizontalAlignment="Left" Margin="690,350,0,0" 
                 VerticalAlignment="Top" Width="270"  Height="278"/>
        <!--復(fù)制文件-->
        <Button x:Name="CopyFile" Content="復(fù)制文件" HorizontalAlignment="Left" 
                Margin="367,650,0,0" VerticalAlignment="Top" Click="CopyFile_Click"/>
        <Button x:Name="PasteFile" Content="粘貼文件" HorizontalAlignment="Left"

        <TextBlock x:Name="TargetFile" HorizontalAlignment="Left" Margin="690,656,0,0"
                   TextWrapping="Wrap" Text="顯示文件拷貝信息" VerticalAlignment="Top" Height="55" Width="450"/>
    </Grid>

　　第六：因?yàn)橐獜?fù)制文件到“庫/文檔"文件夾下面，所以需要設(shè)置如下兩處，具體參考http://www.cnblogs.com/chengxingliang/archive/2012/12/17/2819568.html

設(shè)置文件后綴為jpg的可訪問。
