How to get a stream from a byte array in a windows8 store app

Question

I have been trying get a stream from a byte array in metro style app using the following code.

InMemoryRandomAccessStream memoryStream = new InMemoryRandomAc         


        

Answer 1

I know this is a very old question, but I was running into this issue myself today and figured it out so I'll leave this here for others.

I realized that the stream wasn't being written if it was too small. To fix this, I explicitly set the length of the stream like this:

ms.AsStreamForWrite(imageBytes.Length).Write(imageBytes, 0, imageBytes.Length);

That should be all you need.
