Question

I’ve got a search box which I need to check all words in it against a a string array

So far I’ve got the following code

        For i As Integer = 0 To wordList.Length - 1

            If wordList(i).Contains(TextBox1.Text) Then
                Dim item As String() = New String(0) {}
                item(0) = wordList(i)

                items.Add(item)
            End If

        Next

This checks if the words contain what’s in the textbox in the order it is input but not individual words in any order.

Any ideas how I can check every word in any order and only show words from wordList that contain ALL words?

Thanks in advance

Use LINQ:

Dim words As String() = TextBox1.Text.Split(' 'c);
If words.All(AddressOf someString.Contains) Then

If you don’t want to match text in the middle, you’ll need to use a regex:

If words.All(Function(W) Regex.IsMatch(someString, "\b" + Regex.Escape(w) + "\b"))
