random numbers in C#

[Jad]

i know this question is dull but i need to ask it guys. If i have an array of strings lets say ( string[] array = {"1","2","4","boss","678"} ) and i need to pick one randomly without a specific string lets say "4" (the answer should not never be 4). May i know how ? Thanks for the help,

P.S: i can do it in different ways but i need it in one line of code and that, my friends , i dont know how.

Any help appreciated .... Thanks guys

Hope the following code helps.
----------------------------------------------------
System.Random ran = new System.Random();
string[] array = { "1", "2", "4", "boss", "678" };
MessageBox.Show(array[Convert.ToInt32(ran.Next(0, 5).ToString())]);
