while(count < 20)

{

string next = GetRandomString();

if (Array.IndexOf(strings, next) == -1) // not already in array

{

strings[count] = next;

count++;

}

// print out the strings

foreach(string s in strings) Console.WriteLine(s);

Console.ReadKey();

}

static string GetRandomString()

{

int length = rand.Next(2, 21); // between 2 and 20 characters say

char[] chars = new char[length];

for(int i = 0; i < length; i++)

{

char c = (char)rand.Next(97, 123); // just use letters a to z

chars[i] = c;

}
