Checking for EOF with Streamreader

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Hi. What is the best way to check for EOF when using the streamreader? I am using a do loop. Following is what I have tried but all end in an error when eof is reached.

1. Adding 'until line is nothing' to the end of the loop.
2. Adding 'while not line is nothing' after the do.
3. After the line is read in the do coding:
If line Is Nothing Then
Exit Do
End If

Thanks for your help!
