Array Of Strings Contains Carriage Returns That Can't Be Found

I have used StreamReader to read the contents of a file to its end, and parsed each line into an array entry for an array of strings. That part works, and I have verified that each array entry does contain the proper line entry from the file. However, if I were to go and print out (say, in a MsgBox) each line, every line after the first one would look like (Carriage Return)(proper thing), yet searching for the CRs using InStr yields that there is no CR or ControlChars.NewLine etc. character in the string. I'll show you my code:

Dim FileParse(255) as string
Public Function FileRead(ByVal FILENAME As String)
Dim sr As New System.IO.StreamReader(System.AppDomain.CurrentDomain.BaseDirectory & FILENAME)
Dim FileData As String = sr.ReadToEnd

[code]....

I just set the For Loop from 0 to 10 because I am unsure how to tell the loop to end when it has finished with the last entry of the Lines() array, and since the program will later be writing to the source file, it is likely that the number of lines will change (which is why I just arbitrarily set the FileParse array to have 256 spots).
