OrderBy - Simple 1

This sample uses orderby to sort a list of words alphabetically.

Public Sub Linq28()
    Dim words() = {"cherry", "apple", "blueberry"}

        Order By w

    Console.WriteLine("The sorted list of words:")
    For Each w In sortedWords
        Console.WriteLine(w)
    Next
End Sub

Result:
The sorted list of words:
apple
blueberry
cherry

OrderBy - Simple 2

This sample uses orderby to sort a list of words by length.

Public Sub Linq29()
    Dim words() = {"cherry", "apple", "blueberry"}

    Dim sortedWords = From w In words _
        Select w _
        Order By w.Length

    Console.WriteLine("The sorted list of words (by length):")
    For Each w In sortedWords
        Console.WriteLine(w)
    Next

End Sub

Result:
The sorted list of words (by length):
apple
cherry
blueberry

OrderBy - Simple 3

This sample uses orderby to sort a list of products by name.

OrderBy - Comparer

This sample uses an OrderBy clause with a custom comparer to do a case-insensitive sort of the words in an array.

Public Sub Linq31()
    Dim words() = {"aPPLE", "AbAcUs", "bRaNcH", "BlUeBeRrY", "ClOvEr", "cHeRry"}

    Dim sortedWords = words.OrderBy(Function(a) a, New CaseInsensitiveComparer())

    ObjectDumper.Write(sortedWords)
End Sub

    Public Function Compare(ByVal x As String, ByVal y As String) As Integer Implements System.Collections.Generic.IComparer(Of String).Compare

    End Function
End Class

Result:

Public Sub Linq32()
    Dim doubles() = {1.7, 2.3, 1.9, 4.1, 2.9}

    Dim sortedDoubles = From d In doubles _
        Select d _
        Order By d Descending

    Console.WriteLine("The doubles from highest to lowest:")

This sample uses orderby to sort a list of products by units in stock from highest to lowest.

Public Sub Linq33()
    Dim products = GetProductList()

    Dim sortedProducts = From p In products _
        Select p _
        Order By p.UnitsInStock Descending

    ObjectDumper.Write(sortedProducts)

ThenByDescending - Comparer

This sample uses an OrderBy and a ThenBy clause with a custom comparer to sort first by word length and then by a case-insensitive descending sort of the words in an array.

Public Sub Linq38()
    Dim words() = {"aPPLE", "AbAcUs", "bRaNcH", "BlUeBeRrY", "ClOvEr", "cHeRry"}

    Dim sortedWords = words.OrderBy( _
                            Function(a) a.Length).ThenByDescending( _
                                Function(a) a, New CaseInsensitiveComparer())

    ObjectDumper.Write(sortedWords)
End Sub


Public Class CaseInsensitiveComparer : Implements IComparer(Of String)

    Public Function Compare(ByVal x As String, ByVal y As String) As Integer Implements System.Collections.Generic.IComparer(Of String).Compare
        Return String.Compare(x, y, True)
    End Function
End Class

Result:
aPPLE
ClOvEr
cHeRry
bRaNcH
AbAcUs
BlUeBeRrY

Reverse

This sample uses Reverse to create a list of all digits in the array whose second letter is 'i' that is reversed from the order in the original array.

Public Sub Linq39()
    Dim digits() = {"zero", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine"}

    Dim reversedIDigits = (From d In digits _
        Where d(1) = "i" _
        Select d).Reverse()

    Console.WriteLine("A backwards list of the digits with a second character of 'i':")
    For Each d In reversedIDigits
        Console.WriteLine(d)
    Next
End Sub

Result:
A backwards list of the digits with a second character of 'i':
nine
eight
six
five
