source is Nothing.


source contains no elements.

The Max(IEnumerable(Of Int64)) method uses the Int64 implementation of IComparable(Of T) to compare values.

In Visual Basic query expression syntax, an Aggregate Into Max() clause translates to an invocation of Max.

The following code example demonstrates how to use Max(IEnumerable(Of Int64)) to determine the maximum value in a sequence.

        ' Create a list of Long values. 
        Dim longs As New List(Of Long)(New Long() _
                                       {4294967296L, 466855135L, 81125L})

        ' Get the maximum value in the list. 
        Dim max As Long = longs.Max()

        ' Display the result.
        MsgBox("The largest number is " & max)

        ' This code produces the following output: 
        ' The largest number is 4294967296
