Outofmemory exception when converting picture to byte array

Question

I am working on Windows Phone and I need to convert the images in the phone to a byte array, but the problem is that VisualStudio throws an OutOfMemory exception.

Is there any way to avoid this error? Or an alternative way?

public static byte[] GetBytes(Picture p)
{
    byte[] buffer=new byte[p.GetImage().Length];
    p.GetImage().Read(buffer, 0, buffer.Length);
    return buffer;
}

Yes. Do not load such large of an image. Perhaps you could stream the image rather than load it into memory in one step. — rae1, Jan 20 '14 at 16:36
you could pass the image to the byte array in chunks instead of all at once, maybe it'll help. Are you loading the picture from a folder? Or is it only in memory? — Steven Mills, Jan 20 '14 at 16:40
I try to send the image using chunks, but now I don't know what happen that the stream sends more bytes than the total of the images :S — programmer23, Jan 21 '14 at 08:42

The image is too big for the memory.. Use Stream in System.IO to stream it and save it. That is the most efficient one.

You need to use MemoryStream such as :

public byte[] imageToByteArray(System.Drawing.Image imageIn)
{
 MemoryStream ms = new MemoryStream();
 imageIn.Save(ms,System.Drawing.Imaging.ImageFormat.Gif);
 return  ms.ToArray();
}

Ok, I have found another way to upload images and now it doesn't throw exceptions. I decided to upload the file by chunks, just as Steven Mills. I would like to thank you all for your help.
