Thread: Appending an unsized array

Is there a way to append an unsized array (of strings) to the end of another one? I have the following incomplete function:

Code:

String* all_files(String* sDir)[]
{
		String* f[] = Directory::GetFiles(sDir);
		int numFiles = f->get_Length();

		// The new items in f[] are added to the old ones and stored in files[] (the problem)

		String* d[] = Directory::GetDirectories(sDir);
		int numDirs = d->get_Length();

		for (int i=0; i < numDirs; i++)
		{
			all_files(d[i]);
		}

		return files;
}

(try-catch omitted).

The function basically is *supposed* to return an array of strings containing the full path of all the files in sDir. But I can't figure out how to add the new items in f[] to the old ones to generate the output. Btw as you can see I don't have any definitions for variable "files"; this is because I don't know where to define it. Vectors didn't work here.

Any help is appreciated.
