Word split fails with more then 3 words - vb.net

Question

I try to split a string every + then every |, it works fine when I try to read only 3 words from the split words1(0-3), but when I try to read words1(4) the whole function fails... here is the code:
Private Function SetUpdateData()
Try
Dim delimiterChars As Char() = {"+"c}
Dim words As String() = updatelist.Split(delimiterChars)
Dim i As Integer = 1
Do While (i < words.Length)
Dim delimiterChars1 As Char() = {"|"c}
Dim words1 As String() = words(i).Split(delimiterChars1)
Dim name As String = words1(0)
Dim version As String = words1(1)
Dim fileurl As String = words1(2)
Dim size As String = (words1(3) / 1024D / 1024D).ToString("0.00") & " MB"
Dim cversion As FileVersionInfo = FileVersionInfo.GetVersionInfo(Path.Combine(Directory.GetCurrentDirectory() & "\" & name))
If My.Computer.FileSystem.FileExists(Directory.GetCurrentDirectory() & "\" & name) Then
If Not version.Contains(cversion.FileVersion) Then
DataGridView1.Rows.Add(name, version, size)
RichTextBox1.AppendText("+" & words1(0) & "|" & words1(1) & "|" & words1(2) & "|" & words1(3))
End If
Else
DataGridView1.Rows.Add(name, version, size)
RichTextBox1.AppendText("+" & words1(0) & "|" & words1(1) & "|" & words1(2) & "|" & words1(3))
End If
i = (i + 1)
Loop
Catch ex As Exception
MsgBox("error")
End Try
End Function
This above works no problem at all, but when you add words1(4) in like this:
Private Function SetUpdateData()
Try
Dim delimiterChars As Char() = {"+"c}
Dim words As String() = updatelist.Split(delimiterChars)
Dim i As Integer = 1
Do While (i < words.Length)
Dim delimiterChars1 As Char() = {"|"c}
Dim words1 As String() = words(i).Split(delimiterChars1)
Dim name As String = words1(0)
Dim version As String = words1(1)
Dim fileurl As String = words1(2)
Dim size As String = (words1(3) / 1024D / 1024D).ToString("0.00") & " MB"
Dim status As String = words1(4)
Dim cversion As FileVersionInfo = FileVersionInfo.GetVersionInfo(Path.Combine(Directory.GetCurrentDirectory() & "\" & name))
If My.Computer.FileSystem.FileExists(Directory.GetCurrentDirectory() & "\" & name) Then
If Not version.Contains(cversion.FileVersion) Then
DataGridView1.Rows.Add(name, version, size)
RichTextBox1.AppendText("+" & words1(0) & "|" & words1(1) & "|" & words1(2) & "|" & words1(3) & "|" & words(4))
End If
Else
DataGridView1.Rows.Add(name, version, size)
RichTextBox1.AppendText("+" & words1(0) & "|" & words1(1) & "|" & words1(2) & "|" & words1(3) & "|" & words(4))
End If
i = (i + 1)
Loop
Catch ex As Exception
MsgBox("error")
End Try
End Function
ALSO the string that it is splitting is:
+Thing v2.exe|1.0.0.1|http://example.com/uploads/Thing v2.exe|205824|Primary+Thing v2 DLL.dll|1.0.0.1|http://example.com/uploads/Thing DLL.dll|1097728|Secondary
Which all should output:
words1(0) - Thing v2.exe
words1(1) - 1.0.0.1
words1(2) - http://example.com/uploads/Thing v2.exe
words1(3) - 205824
words1(4) - Primary
But as I said above once words1(4) is used it crashes the whole function...
It will catch and fail and give the error message, but when I try to do msgbox(ex) for the exception error, no msgbox pops up and the program just continues.
If anyone can fix the issue or give me some help that would be greatly appreciated, thanks in advance and sorry if this is confusing as it is to me too!

Answer 1

There are two loops in your program:
Loop1:
words1(0)>>Thing v2.exe
words1(1)>>1.0.0.1
words1(2)>>http://example.com/uploads/Thing v2.exe
words1(3)>>205824
words1(4)>>Primary
Loop2:
words1(0)>>Thing v2 DLL.dll
words1(1)>>1.0.0.1
words1(2)>>http://example.com/uploads/Thing DLL.dll
words1(3)>>1097728
words1(4)>>Secondary
it appears that you misspelled your words1(4) to words(4) in below line
RichTextBox1.AppendText("+" & words1(0) & "|" & words1(1) & "|" & words1(2) & "|" & words1(3) & "|" & words(4))

Answer 2

Your split functionality works fine but there's an error on the following lines (there are 2 of them):
RichTextBox1.AppendText("+" & words1(0) & "|" & words1(1) & "|" & words1(2) & "|" & words1(3) & "|" & words(4))
The last words(4) should be words1(4).
