Edit

Contains static properties that return string values. Each string corresponds to a known format ID. Use this class to avoid errors in using string constants to specify data formats.

Examples

This example shows how to retrieve shared text (by using StandardDataFormats.Text) or a shared file or folder (by using StandardDataFormats.StorageItems). For more examples, see the Clipboard sample and the ShareTarget sample.

public async Task ActivateAsync(ShareTargetActivatedEventArgs args)
{
    ShareOperation shareOperation = args.ShareOperation;
    if (shareOperation.Data.Contains(StandardDataFormats.Text))
    {
        string text = await shareOperation.Data.GetTextAsync();

        // To output the text from this example, you need a TextBlock control
        // with a name of "sharedContent".
        sharedContent.Text = "Text: " + text;
    }

    if (shareOperation.Data.Contains(StandardDataFormats.StorageItems)) 
    {
        shareOperation.ReportStarted();
        IReadOnlyList<IStorageItem> storageItems = null;
        storageItems = await shareOperation.Data.GetStorageItemsAsync();
        string fileList = String.Empty;

        for (int index = 0; index < storageItems.Count; index++) 
        {
            fileList += storageItems[index].Name;
                if (index < storageItems.Count - 1) {
                    fileList += ", ";
                }
            }

        // To output the text from this example, you need a TextBlock control
        // with a name of "sharedContent".
        sharedContent.Text += "StorageItems: " + fileList + Environment.NewLine;

        shareOperation.ReportCompleted();
    }

    Window.Current.Content = this;
    Window.Current.Activate();
}

Remarks

The DataPackage class supports several format types. Whenever you need to specify a format, we recommend using the properties of the StandardDataFormats class, instead of string values. Doing so ensures consistency between source and target applications.

The DataPackage class supports a number of legacy formats for interoperability between UWP app and desktop apps. To retrieve these formats, you pass one of the following strings to the DataPackageView.GetDataAsync method instead of a value from the StandardDataFormats class.

If format name is:	GetDataAsync() retrieves:
"AnsiText"	String for CF_TEXT.
"DeviceIndependentBitmap"	Stream for HGLOBAL corresponding to CF_DIB.
"DeviceIndependentBitmapV5"	Stream for HGLOBAL corresponding to CF_DIBV5.
"DataInterchangeFormat"	Stream for HGLOBAL corresponding to CF_DIF.
"EnhancedMetafile"	Stream for HENHMETAFILE corresponding to CF_ENHMETAFILE.
"Locale"	Stream for HGLOBAL corresponding to CF_LOCALE
"OEMText"	String for CF_OEMTEXT.
"PenData"	Stream for HGLOBAL corresponding to CF_PENDATA
"RiffAudio"	Stream for HGLOBAL corresponding to CF_RIFF.
"SymbolicLink"	Stream for HGLOBAL corresponding to CF_SYLK.
"TaggedImageFileFormat"	Stream for HGLOBAL corresponding to CF_TIFF.
"WaveAudio"	Stream for HGLOBAL corresponding to CF_WAVE.

The Windows Runtime provides limited support for metafiles. Specifically, the Windows Runtime:

Supports rendering metafiles, but not creating them.
Supports the CF_ENHMETAFILE format ("EnhancedMetafile"), but not CF_METAFILEPICT.
Supports requesting data in "EnhancedMetafile" format, but not providing it; that is, calling SetData("EnhancedMetafile", <data>) won't work.
Provides limited support through the clipboard API for exchanging metafiles between UWP app and desktop apps.
