UWP 剪贴板 Clipboard

Clipboard使用Windows.ApplicationModel.DataTransfer.Clipboard

设置文本

DataPackage dataPackage = new DataPackage();
dataPackage.SetText("文本");
Clipboard.SetContent(dp);      

获取文本

检查剪贴板包含文本

DataPackageView con = Windows.ApplicationModel.DataTransfer.Clipboard.GetContent();
if (con.Contains(StandardDataFormats.Text))
{

            DataPackageView con = Windows.ApplicationModel.DataTransfer.Clipboard.GetContent();
            string str = string.Empty;
            if (con.Contains(StandardDataFormats.Text))
            {
                str = await con.GetTextAsync();
            }
}      

获取图片

if (con.Contains(StandardDataFormats.Bitmap))
            {
                RandomAccessStreamReference img = await con.GetBitmapAsync();
                var imgstream = await img.OpenReadAsync();
                BitmapImage bitmap = new BitmapImage();
                bitmap.SetSource(imgstream);

                Windows.UI.Xaml.Media.Imaging.WriteableBitmap src = new Windows.UI.Xaml.Media.Imaging.WriteableBitmap(bitmap.PixelWidth, bitmap.PixelHeight);
                src.SetSource(imgstream);

                Windows.Graphics.Imaging.BitmapDecoder decoder = await Windows.Graphics.Imaging.BitmapDecoder.CreateAsync(imgstream);
                Windows.Graphics.Imaging.PixelDataProvider pxprd = await decoder.GetPixelDataAsync(Windows.Graphics.Imaging.BitmapPixelFormat.Bgra8, Windows.Graphics.Imaging.BitmapAlphaMode.Straight, new Windows.Graphics.Imaging.BitmapTransform(), Windows.Graphics.Imaging.ExifOrientationMode.RespectExifOrientation, Windows.Graphics.Imaging.ColorManagementMode.DoNotColorManage);
                byte[] buffer = pxprd.DetachPixelData();

                str = "image";
                StorageFolder folder = await _folder.GetFolderAsync(str);

                StorageFile file = await folder.CreateFileAsync(DateTime.Now.Year.ToString() + DateTime.Now.Month.ToString() + DateTime.Now.Day.ToString() + DateTime.Now.Hour.ToString() + DateTime.Now.Minute.ToString() + ".png", CreationCollisionOption.GenerateUniqueName);

                using (var fileStream = await file.OpenAsync(FileAccessMode.ReadWrite))
                {
                    var encoder = await Windows.Graphics.Imaging.BitmapEncoder.CreateAsync(Windows.Graphics.Imaging.BitmapEncoder.PngEncoderId, fileStream);
                    encoder.SetPixelData(Windows.Graphics.Imaging.BitmapPixelFormat.Bgra8, Windows.Graphics.Imaging.BitmapAlphaMode.Straight, decoder.PixelWidth, decoder.PixelHeight, decoder.DpiX, decoder.DpiY, buffer);
                    await encoder.FlushAsync();
                }
            }      

获取文件

if (con.Contains(StandardDataFormats.StorageItems))
            {
                var filelist = await con.GetStorageItemsAsync();
                foreach (StorageFile t in filelist)
                {

                }
            }      

IStorageItem 转 StorageFile

if (t.IsOfType(StorageItemTypes.File))
                    {
                        StorageFile storageFile = storageItem as StorageFile;
                    }
