title: What's the best way to read/write array contents from/to binary files in C#?
body: <p>I would like to read and write the contents of large, raw volume files (e.g. MRI scans).  These files are just a sequence of e.g. 32 x 32 x 32 floats so they map well to 1D arrays.  I would like to be able to read the contents of the binary volume files into 1D arrays of e.g. float or ushort (depending on the data type of the binary files) and similarly export the arrays back out to the raw volume files.</p>
  
  <p>What's the best way to do this with C#?  Read/Write them 1 element at a time with BinaryReader/BinaryWriter?  Read them piece-wise into byte arrays with FileStream.Read and then do a System.Buffer.BlockCopy between arrays?  Write my own Reader/Writer?</p>
  
  <p>EDIT: It seems it's not possible to work with > 2GB arrays, but the question still stands for smaller arrays (around 256 MB or so)</p>
