Randomly choose an array C#

Question

I have 6 string arrays that contain a series of characters. What I would like to be able to do is random pick an array and once its picked afterwards, will produce a final string response. Do I need a list to do this or is there another way?

All of this is just an small array exercise using a random variable.

I should specify that this is a console application.

Please show what you've tried thus far. You might need a list or some such if you don't want to repeat the same string twice... — Lee Taylor, Jan 28 '13 at 20:17
I'd probably look into the `Random` class, but maybe that's just me. — Dave Zych, Jan 28 '13 at 20:18
Please provide some code, maybe it's easier to understand what you would like to achieve. — Alex Filipovici, Jan 28 '13 at 20:18

You use [`Random`](http://msdn.microsoft.com/en-us/library/system.random.aspx) to generate a random number, and then use the array that corresponds to that number. See [this answer](http://stackoverflow.com/a/3975307/298754) for an example. — Bobson, Jan 28 '13 at 20:18

A simple option would be: Make an array of the arrays. Pick a random index to get one of the arrays. Create a reference to this and then pick each member as needed.

here is what I have done to put all of those arrays in one. string[][] options = new string[][]{one, two, three, four, five...}; – Karim O. Jan 28 '13 at 21:05

        //let say u have an array of string
        string[] myarr = new string[] { "str1", "str3", "str3", "str4", "str5", "str6"};

        Random rnd = new Random();
        // you dont need a list, simply pick one rnd element from array
        string myRandomPickedString = myarr[rnd.Next(0, myarr.Length - 1)];
