Saving File to Byte Array in Windows 8 WinRT

I’ve been hitting my head to the ground for a couple of days trying send a byte array that represents my Image to my WCF Service in Windows 8, things has changed a lot when it comes to IO and Streams in Windows 8 so I included my code here for others to use

 

 

 

 

 

 

 

Covert File to Byte Array

1. private async Task<byte[]> ConvertImagetoByte(StorageFileimage)
2.       {
3.           IRandomAccessStream fileStream = await image.OpenAsync(FileAccessMode.Read);
4.           var reader = new Windows.Storage.Streams.DataReader(fileStream.GetInputStreamAt(0));
5.           await reader.LoadAsync((uint)fileStream.Size);
6.  
7.           byte[] pixels = new byte[fileStream.Size];
8.  
9.           reader.ReadBytes(pixels);
10.  
11.           return pixels;
12.  
13.       }

  this is old but for the next guy who finds this off a search engine like i did: add: (IBuffer.ToArray() is defined in WindowsRuntimeBufferExtensions) using System.Runtime.InteropServices.WindowsRuntime; then just do: var buffer = await FileIO.ReadBufferAsync(image); var bytes = buffer.ToArray();
