No, multiple catch blocks cannot be executed. Once first catch block is catched, it will not read the next block.
What happens if you use multiple catch blocks for the same exception?
If you use multiple catch blocks for the same type of exception, then it will give you a compile-time error because C# does not allow you to use multiple catch block for the same type of exception. A catch block is always preceded by the try block.
Can you catch multiple exceptions at the same time?
Remember, though, that if all the exceptions belong to the same class hierarchy, you can simply catch that base exception type. Also note that you cannot catch both ExceptionA and ExceptionB in the same block if ExceptionB is inherited, either directly or indirectly, from ExceptionA.
How to handle exceptions associated with a single Try block?
Now we use two catch blocks to handle these exceptions that are associated with a single try block. Each catch block caught a different type of exception like catch block 1 is used to catch DivideByZeroException, catch block 2 is used to catch IndexOutOfRangeException. Example 2: In the below example, try block raise an exception.
How many exceptions can you catch per customer?
No, one per customer. You can catch a superclass, like java.lang.Exception, as long as you take the same action in all cases. But that might not be the best practice. You should only catch an exception when you have a strategy for actually handling it – and logging and rethrowing is not “handling it”.
