Using a List(Of String) is better because you don't need to know the size of the array.
Of course you need to initialize the List(Of String) before usage.

Function ConvertBinaryToASCII(ByVal input As String) As String
    Dim ASCIIList() As String = .....
    Dim BinaryList() As String = ......
    Dim BinarySubstrings = Enumerable.Range(0, input.Length \ 8).[Select](Function(i) input.Substring(i * 8, 8)).ToArray()
    Dim result = new List(Of String)()
    Dim binaryMatch As Integer

    For Each e As String In BinarySubstrings
        binaryMatch = Array.IndexOf(BinaryList, e)
        result.Add(ASCIIList(CInt(binaryMatch)))
    Next

    Return String.Join("", result.ToArray())
End Function
