Stream stream = WriteableBitmap.PixelBuffer.AsStream() missing

问题

I'm writing windows store app (8.1) and I have sample (probably for win 8.0):

private WriteableBitmap WriteableBitmap;
…
WriteableBitmap = new WriteableBitmap(500,500);
…
using (Stream stream = WriteableBitmap.PixelBuffer.AsStream())
{
    …
}

So I have created new win 8.1 project and trying to do it same way, but when I get to:

using (Stream stream = WriteableBitmap.PixelBuffer.AsStream())

My project dont recognize *.AsStream() method, can anyone tell me why?

回答1:

using System.Runtime.InteropServices.WindowsRuntime;
