Join Bruce Van Horn for an in-depth discussion in this video Using multiple catch statements, part of C# Essential Training: 2 Flow Control, Arrays, and Exception Handling.
- [Instructor] We've seen the simplest form…of Try/Catch,…why don't we expand this a little bit.…Generally speaking,…most people don't like the Try/Catch with no…exception in here…because effectively,…it catches anything and it isn't really…granular enough.…So a better way to do this,…generally speaking,…is to actually capture a particular exception…and react accordingly.…In this case,…what we could do is we could actually comment out…those parts that are the Try/Catch block,…and this would allow us to see the actual exception…as it happens so that we would know exactly what…kind of exception is being thrown.…
So I'll comment these out,…I'll go ahead and run my program,…and it's going to crash.…I can see that the exception here is…system.io directory not found exception,…I'm going to highlight the exception name,…I'm going to copy this,…and now I can actually detect that in my code.…Of course before I can edit my code,…I need to stop the run.…And now let me go back and…take these comments back out,…and now armed with the actual exception,…
