我正在写windows store app(8.1),我有样本(可能是win 8.0):
private WriteableBitmap WriteableBitmap;
…
WriteableBitmap = new WriteableBitmap(500,500);
…
using (Stream stream = WriteableBitmap.PixelBuffer.AsStream())
{
…
}
所以我创建了新的win 8.1项目并尝试以同样的方式进行,但是当我到达时:
using (Stream stream = WriteableBitmap.PixelBuffer.AsStream())
我的项目不承认*.AsStream()
方法,有人可以告诉我原因吗?
