How do I read shorts from a binary file starting at position x, for y values?

Question

I need to read a certain amount of short (int16) data points from a binary file, starting at a specific position. Thanks!

Answer 1

You can simply call the Seek method on the Stream that you pass to BinaryReader to the position in the file you want to start reading from.

Then, once you pass the stream to BinaryReader, you can call the ReadInt16 method as many times as you need to.

Answer 2

Something like this should do it for you:

private IEnumerable<Int16> getShorts(string fileName, int start, int count)
using(var stream = File.OpenRead(fileName))
{
   stream.Seek(start);
   var reader = new BinaryReader(stream);
   var list = new List<int16>(count);
   for(var i = 0;i<count;i++)
   {
      list.Add(reader.ReadInt16());
   }
}

which is basically what CAsper wrote just in code
