Try and load it using the appropriate library built to parse that kind of file.
Other than that, you have to examine each and every byte yourself, parsing the file yourself, and validating all the data yourself. For every kind of file format, that's an enormous amount of work.

If your application is meant to handle almost any kind of file, then you have a tough job. Every file essentially is a series of bytes. Unless you scan that and then try to match it with actual pattern, I can't think of a concrete solution.
You can try opening the file with the associated program. That too will not guarantee detection since many file will open (although distorted and with weird characters) in the associated program.
I found this[^] through google. You can check if it helps.

Your post doesn't make much sense at all, so, point-by-piont:

C# and the .NET Framework has no managed classes to do this. You must use an outside library.

Yeah. And?

Is there any way to do optional variable declaration in c# 3.5.
I have two alternatives.
(a) Function Overloading
(b) declaring the function arguments in Params Object[] variable
Can i do it exactly the way we can do in vb.net ?
|
|
|
|
|
C# 4.0 introduces optional parameters, you can't do it in 3.5.

Why would you ever compare anything to VB?

OK, well you can do optional parameters in C++. Would that have been a better comparison? Kevin

Yes, VB and C++ are much closer.

hello everyone!!
I have a problem.
i build a service and i build install to.
i install my service and is work beautiful.
but...if he as a error he stop the service and write to my even log.
i dont want to stop my service if he as a error.what i do?how to fix that?
|

Services stop when an unhandled exception is thrown, so you need to make sure you handle them. You could maybe do this quite high up - do you have a loop on a thread created in OnStart()?
However, that just assumes you can just carry on if something bad happens. You really need to consider the execution path which may result from an exception being thrown. If you get a network error, you might want to try again a short while later. If you run out of memory or disc space, you probably do want the service to stop...Regards,
Rob Philpott.

If you have a form you need localized, in the designer view, set its Localizable property to be true, then set it's Language property to be whatever language you are localizing. This essentialy creates a second copy of the form, in which you can change the text on all the controls, resize them to fit different length text, while still allowing you to switch back to the default language without the resizes and the text changes. All of you work will automatically get stored in a resex file.
