Why can't I write just a try with no catch or finally?

Hi, One of the important exception handling in C# is try and catch.Simplay way you are trying something inside the try block. Suddenly you get some exceptions inside the try block and those exception automatically catch by catch block. So we can easily identify and fix the bug. Catch is mandatory but finally is not.

If you don't want to catch it, why are you using try in the first place?

A try statement means that you believe something can go wrong, and the catch says that you can adequately handle that which you catch.

So in your estimation:

try
{
//Something that can go wrong
}
catch
{
//An empty catch means I can handle whatever goes wrong. If a meteorite hits the
//datacenter, I can handle it.
}

That catch swallows any exceptions that happen. Are you that confident in your code that you can handle anything that goes wrong gracefully?

The best thing to do (for both yours and your maintenance programmer's sanity) is to explicitly state that which you can handle gracefully:

try
{
//Something that could throw MeteoriteHitDatacenterException
}
catch (MeteoriteHitDatacenterException ex)
{
//Please log when you're just catching something. Especially if the catch statement has side effects. Trust me.
ErrorLog.Log(ex, "Just logging so that I have something to check later on if this happens.")
}

For your easy understanding Try is some problem like (Fever) To recover that problem we need different medicines so we keep them in catch block. In general we can have multiple catch blocks but finally is optional one.

Try Catch is used to exception handling in c#. try is for the coe which we need to run and can throw some exception.
And we require catch to catch that exception and handle it the way we need to.
