VB.NET Count bits, 1's are counted as 1, Zero's are counted together in a sequence between 1's - vb.net

Question

Looking to count bits in a sequence.
1's are counted as 1, Zero's are counted together in a sequence between 1's
If you look at this picture
The output should be 2,1,5,1,1,3,2,1
Here is my code it works on 80% of numbers sometimes it messes up.
dim bitmask() as byte
redim bitmask(15)
bitmask(0) = 0
bitmask(1) = 0
bitmask(2) = 1
bitmask(3) = 0
bitmask(4) = 0
bitmask(5) = 0
bitmask(6) = 0
bitmask(7) = 0
bitmask(8) = 1
bitmask(9) = 1
bitmask(10) = 0
bitmask(11) = 0
bitmask(12) = 0
bitmask(13) = 1
bitmask(14) = 0
bitmask(15) = 1
Public Function GetBitCount() As Byte()
Dim count As Byte = 0
Dim bitcounts As New List(Of Byte)
Dim indexOfNext As Integer = 0
Dim totalCounted As Integer = 0
While True
indexOfNext = Array.IndexOf(bitmask, CByte(1), indexOfNext + 1)
If indexOfNext > 0 Then
If indexOfNext - totalCounted = 1 Then
bitcounts.Add(2)
bitcounts.Add(1)
ElseIf indexOfNext - totalCounted > 0 Then
bitcounts.Add(IIf(totalCounted > 0, indexOfNext - totalCounted, indexOfNext))
ElseIf indexOfNext - totalCounted > 1 Then
bitcounts.Add(2)
bitcounts.Add(1)
Else
bitcounts.Add(1)
bitcounts.Add(1)
End If
If totalCounted = 0 Then bitcounts.Add(1)
totalCounted = indexOfNext + 1
Else
Exit While
End If
End While
If totalCounted - 1 > 2 AndAlso totalCounted - 1 < bitmask.Length - 1 Then
bitcounts.Add(1)
bitcounts.Add((bitmask.Length - 1) - (totalCounted - 1))
ElseIf totalCounted - 1 <= 2 AndAlso totalCounted - 1 < bitmask.Length - 1 Then
bitcounts.Add((bitmask.Length - 1) - (totalCounted - 1))
Else
bitcounts.Add(1)
End If
If count > 0 Then bitcounts.Add(count)
Return bitcounts.ToArray()
End Function

Solution
Public Function GetBitCount() As Byte()
Dim i As Integer = 0
Dim count As Byte = 0
Dim bitcounts As New List(Of Byte)
For i = 0 To bitmask.Length - 1
If bitmask(i) = 1 Then
bitcounts.Add(count)
count = 0
End If
count += 1
Next
If count > 0 Then bitcounts.Add(count)
Return bitcounts.ToArray()
End Function
