BitmapImage result =newBitmapImage(); result.BeginInit();// According to MSDN, "The default OnDemand cache option retains access to the stream until the image is needed."// Force the bitmap to load right now so we can dispose the stream.result.CacheOption = BitmapCacheOption.OnLoad; res...
有时要实现BitmapImage与byte[]相互转换,这里实现两个静态方法,直接调用即可。 byte[]转换为BitmapImage: publicstaticBitmapImage ByteArrayToBitmapImage(byte[] byteArray) { BitmapImage bmp=null; try { bmp=newBitmapImage(); bmp.BeginInit(); bmp.StreamSource=newMemoryStream(byteArray); bmp.EndInit...
基本上它所做的是创建一个MemoryMappedFile和视图，并附加ImageSource到文件部分。这个ImageSource连接（依赖...
publicstaticBitmapImageLoadFromBytes(byte[] bytes){using(varstream =newMemoryStream(bytes)) {varimage =newBitmapImage(); image.BeginInit(); image.CacheOption = BitmapCacheOption.OnLoad; image.StreamSource = stream; image.EndInit();returnimage; } } ...
