Put all 100 words in array, and apply for loop over 100 words; take a new hashtable, create a string of 3 words combining with underscore(_). Add this key value pair in hashtable, before adding you can check whether string is already added or not..

Hope this will help you.

Using LINQ:

Module Module1
    Sub Main()
        Dim wordList As New List(Of String)() From
        {
            "dog",
            "cat",
            "bird",
            "monkey",
            "mouse",
            "fish",
            "whale",
            "horse",
            "chicken"
        }

        Dim query = From firstWord In wordList
                    From secondWord In wordList
                    From thirdWord In wordList
                    Where firstWord <> secondWord AndAlso
                          firstWord <> thirdWord AndAlso
                          secondWord <> thirdWord
                    Select String.Format("{0}_{1}_{2}", firstWord, secondWord, thirdWord)

        For Each item In query
            Console.WriteLine(item)
        Next

        Console.ReadKey()
    End Sub
End Module

Open in new window


The multiple From effectively give you a Cartesian join of all the words. Then it simply becomes a matter of excluding the ones you don't want--in this case, the ones containing duplicates.
