这一节,顾名思义,即使你要共享数据给别人,你是数据的提供者。
分两步即可
1、直接复制代码
protected override void OnNavigatedTo(NavigationEventArgs e) { DataTransferManager.GetForCurrentView().DataRequested += Page_DataRequested; } protected override void OnNavigatedFrom(NavigationEventArgs e) { DataTransferManager.GetForCurrentView().DataRequested -= Page_DataRequested; } void Page_DataRequested(DataTransferManager sender, DataRequestedEventArgs args) { var deferral = args.Request.GetDeferral(); //Image { args.Request.Data.Properties.Title = "Exif Info Share"; args.Request.Data.Properties.Description = "From Exif Info";// The description is optional. RandomAccessStreamReference imageStreamRef = RandomAccessStreamReference.CreateFromFile(file); args.Request.Data.Properties.Thumbnail = imageStreamRef; args.Request.Data.SetBitmap(imageStreamRef); } //StorageFile { //args.Request.Data.Properties.Title = "Exif Info Share"; //args.Request.Data.Properties.Description = "From Exif Info";// The description is optional. //List<IStorageItem> files = new List<IStorageItem>(); //files.Add(file); //args.Request.Data.SetStorageItems(files); } deferral.Complete(); }
2、最后
private void Btn_Share_Click(object sender, RoutedEventArgs e) { DataTransferManager.ShowShareUI(); }
