Can you help me how this can be done?

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
