Copy string array to an existing string array in C#

Question

 String[] search1 = Directory.EnumerateFiles(voiceSource, callId + " "+ separator +"*."+ fileFormat +"")
                         .Where(file => Path.GetFileName(file).StartsWith( callId + " "+ separator +""))
                         .Select(path => Path.GetFileName(path))
                         .ToArray();

Now I would like to copy the following array to the above search1. On the other word, I would like to combine two array.

  String[] search2 = Directory.EnumerateFiles(voiceSource, callId + ""+ separator +"*."+ fileFormat +"")
                         .Where(file => Path.GetFileName(file).StartsWith(callId + ""+ separator +""))
                         .Select(path => Path.GetFileName(path))
                         .ToArray();

Please note that search1 may be of zero length. Any help?

It's not really clear to me what you are trying to achieve - can you clarify? — BrokenGlass, Jan 25 '15 at 07:03

Do you mean you want to just concatenate two arrays? If so, use LINQ: `a.Concat(b).ToArray()` — Ian Mercer, Jan 25 '15 at 07:08

search3 = new type[search1.Length + search2.Length];
search1.CopyTo(search3, 0);
search2.CopyTo(search3, search1.Length);

where type is the type of element in array

from How do I concatenate two arrays in C#?

Instead of copying the code from another answer, flag as duplicate of the other question. – Patrick Hofman Jan 25 '15 at 07:16
