The BinaryStream class is an input/output mechanism for reading and writing arbitrary binary data. It can be used with MemoryBlocks and FolderItems.
The Read/Write methods raise an exception when reading or writing past the end of the stream. File IO prevents thread switching.
Load an image that is copied to an iOS app using a Copy Files Build Step:
Dim b As BinaryStream
b = BinaryStream.Open(f, BinaryStream.LockModes.Read)
Dim mb As New MemoryBlock(b.Read(b.Length))
Dim image As iOSImage
image = Image.FromData(mb)
ImageView1.Image = image
