我想将 winrt 中剪贴板内的一张图像保存到文件中。但我没有找到办法。你能帮忙吗?
var dataPackage = Clipboard.GetContent();
var t = await dataPackage.GetBitmapAsync();
var t2 = await t.OpenReadAsync();
t2.AsStream();
t2.Seek(0);
BitmapImage bitmapImage = new BitmapImage();
bitmapImage.SetSource(t2);
Image image = new Image();
image.Source = bitmapImage;<
干得好 :)
请注意,您不能使用任何文件夹来保存。我已经通过了ApplicationData.Current.LocalFolder.Path
作为目的地。您可以使用FolderPicker
然后传递所选文件夹的路径。
private async Task StoreImageFromClipboardAsync()
{
var dataPackage = Clipboard.GetContent();
var formats = dataPackage.AvailableFormats;
if (formats.Contains("Bitmap"))
{
var t = await dataPackage.GetBitmapAsync();
var file = await ChangeIRASRToStorageFileAsync(t, ApplicationData.Current.LocalFolder.Path, "Clipboard.png");
}
}
private async Task<StorageFile> ChangeIRASRToStorageFileAsync(IRandomAccessStreamReference MyIRASR, String StorageFolderPath, String StorageFileName)
{
IRandomAccessStreamWithContentType MyIRASWCT = await MyIRASR.OpenReadAsync();
StorageFolder MyStorageFolder = await StorageFolder.GetFolderFromPathAsync(StorageFolderPath);
StorageFile MyStorageFile = await MyStorageFolder.CreateFileAsync(StorageFileName, CreationCollisionOption.ReplaceExisting);
Windows.Storage.Streams.Buffer MyBuffer = new Windows.Storage.Streams.Buffer(Convert.ToUInt32(MyIRASWCT.Size));
IBuffer iBuf = await MyIRASWCT.ReadAsync(MyBuffer, MyBuffer.Capacity, InputStreamOptions.None);
await FileIO.WriteBufferAsync(MyStorageFile, iBuf);
return MyStorageFile;
}
