Getting Started with Windows 8 Development (14) use of the Pasteboard (clipboard) in Windows 8

In Windows 8, our Pasteboard holds 4 kinds of information: text, pictures, Web pages, files. In this article we will copy and paste each of these 4 elements, of course, you can also copy the 4 elements externally, and then paste it in the program.

Datapackage: Contains data that the user wants to exchange with another application

Set a relay variable to save the user's value
       datapackage dp = new Datapackage ();

First: Let's take a look at the background processing code for copying and pasting text.

<!--copy text-->
        private void Copytext_click (object sender, RoutedEventArgs e)
        {
            DP. SetText (this. Sourcetext.text);
            Clipboard.setcontent (DP);
        <!--paste text-->
        private async void Pastetext_click (object sender, RoutedEventArgs e)
        {
            var Clipboarddata = Clipboard.getcontent ();
            if (Clipboarddata.contains (standarddataformats.text))
            {this
                . Targettext.text = await clipboarddata.gettextasync ();
            }
        }

Second: Copy and paste picture background processing code

//<!--Copy picture--> 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);
            //<!--paste Picture--> private async void Pasteimage_click (object sender, RoutedEventArgs e) {
            var clipboarddata = clipboard.getcontent (); if (Clipboarddata.contains (Standarddataformats.bitmap)) {randomaccessstreamreference img = AW
                AIT Clipboarddata.getbitmapasync (); var imgstream = await img.
                OpenReadAsync ();
                BitmapImage bitmap = new BitmapImage (); Bitmap.
                SetSource (Imgstream); This.
            Targetimage.source = bitmap; }
        }

Third: Copy and paste the HTML background processing code

<!--copy 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);
        <!--paste 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);
            }
        

Four: Copy and paste the background code of the file

<!--copy files--> 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);
            //<!--paste file--> 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 + file Paste one copy to library \ \ document \ \ + sfile.
                Name+ "\ r"; }
            }
        }
