return a variable length string array

Question

what's the best method to return a variable length string array

Answer 1

I'd prefer to use a generic collection such as: List<string> (or IList<string>), or IEnumerable<string> depending on how you plan to use it. Generic collections are typically easier to work with than arrays, having a much more robust interface.

Answer 2

There is nowhere near enough detail in your question to understand exactly what you are after.

This works though:

string[] GetStringArray(int length) {
    return new string[length];
}

(C# isn't like C, if that is your concern.)
