Question

Answer 1

In C# 8, range operators allow:

var dest = source[100..200];

(and a range of other options for open-ended, counted from the end, etc)

Before that, LINQ allows:

var dest = source.Skip(100).Take(100).ToArray();

or manually:

var dest = new MyType[100];
Array.Copy(source, 100, dest, 0, 100);
       // source,source-index,dest,dest-index,count
