    Object reference not set to an instance of an object for streamreader object

    See the end of this message for details on invoking
    just-in-time (JIT) debugging instead of this dialog box.

    ************** JIT Debugging **************
    To enable just-in-time (JIT) debugging, the .config file for this
    application or computer (machine.config) must have the
    jitDebugging value set in the system.windows.forms section.
    The application must also be compiled with debugging
    enabled.

    For example:

    <configuration>
    <system.windows.forms jitDebugging="true" />
    </configuration>

    When JIT debugging is enabled, any unhandled exception
    will be sent to the JIT debugger registered on the computer
    rather than be handled by this dialog box.

    So, do you have a specific question for us, or are you just proud of your debug message?
