Join Gerry O'Brien for an in-depth discussion in this video Challenge: Handle an error, part of Up and Running with C#.
In this challenge, you're going to write structured exception handling to handle a…specific error that will be generated by the code you see on screen.…The challenge starts with code that I have already written, where…I'm declaring integer values, an object value, and a string value.…I will attempt to perform a cast using this statement here.…Your objective in this challenge is to use the existing code in Visual Studio.…Create the appropriate exception handling routine to wrap…the protected code that will generate the error.…You'll need to catch the InvalidCastException that is generated,…and you'll want to output the exception message to the screen.…
With the starter code, writing the exception…handling should take you approximately 10 minutes.…
