LINQ to get an Item from an array and Debug.WriteLine it.

[ebellounisoft]

Starting to use LINQ. Using this LINQ code to Filter in strings in an array that Contain the word Visual.

Dim words() As String = {"Visual Basic", "Java", "Visual Studio"}

        Dim selectedWords = From word In words
                            Where word.ToUpper.Contains("VISUAL")
                            Select word

        For Each word In words
            Debug.WriteLine(word.ToString)
        Next

The result is :

Visual Basic
Java
Visual Studio

Not the one I expected and looking for. With Array.Filter works ok but I what to learn how to do it with LINQ. The output should be:

Visual Basic
Visual Studio

What is wrong ?. Thank you.

Solved it.

 Dim words() As String = {"Visual Basic", "Java", "Visual Studio"}

        Dim selectedWords = From word In words
                            Where word.ToUpper.Contains("VISUAL")
                            Select word

        For Each wrd In selectedWords
            Debug.WriteLine(wrd.ToString)
        Next

RESULT:

Visual Basic
Visual Studio

For the record here is another method

Module Module1
Sub Main()
    Dim words() As String = {"Visual Basic", "Java", "Visual Studio"}
    Dim selectedWords = From item In
                        words Where item.IndexOf("visual", StringComparison.CurrentCultureIgnoreCase) > -1
    For Each word As String In selectedWords
        Console.WriteLine($"->{word}")
    Next
    Console.ReadLine()
End Sub
End Module

well heck, as long as we're showing off here....

        Dim words() As String = {"Visual Basic", "Java", "Visual Studio"}
        Array.ForEach(words.Where(Function(w) w.Contains("Visual")).ToArray, Sub(w) Console.WriteLine(String.Format("-> {0}", w)))
