I do not believe there is a property that will allow for you to check if the streamreader is open or not.

Best practice seems to be to .close the reader when done with it. (All in the method that it was used in.)

You could try a try block to handle the exception if you are still getting one.

May be able to find additional info and some sample code here. Good Luck.

MSDN! StreamReader

EDIT: You may be able to check using this. IO.File

Private Function CheckFile(ByVal filename As String) As Boolean

    Try
        System.IO.File.Open(filename, IO.FileMode.Open, IO.FileAccess.Read, IO.FileShare.None)
        FileClose(1)
        Return False
    Catch ex As Exception
        Return True
    End Try

End Function
