Question

A have the string array and I need to select 9 elements starting from 20:

 string sel = data.Skip(19).Take(9).ToString();

Where is error?

SOLUTION:

string sel = String.Concat(data.Skip(19).Take(9).ToArray());

Answer 1

Take(9) returns an IEnumerable<string>. When you call ToString() on it you just get the name of the type. You need to do this instead:

var selected = data.Skip(19).Take(9).ToArray();

selected is now of type string[] and should contain 9 elements (if data contains enough elements, that is).
