Please Explain

Hi All

Can anyone help me in understanding the highlighted text please.

For Each row As DataRow In ds.Tables(0).Rows
Dim arr() As Object = row.ItemArray()
For i As Integer = 0 To arr.Length - 1

If arr(i).ToString().IndexOf(",") > 0 Then ' I m unable to get this line of code.

record = record & Chr(34) & arr(i).ToString() & Chr(34) & ","
Else
record = record & arr(i).ToString() & ","
End If
Next
body = body & record.Substring(0, record.Length - 1) & vbCrLf
record = ""
Next

Thanks

take the object in Array arr at position indicated by i

convert to a string

find the index (position) of a comma character

see if the comma occurred after the first character position

Hi there
