Try and catch block Interview questions

Try and catch block

Difference btw throw end throw ex.

I am writing this post someone asked to me and I never heard earlier before.

I thought both are same, and one of them give an error, but both are wrong,

Now I have try to give you a proper answer

Similarities:

Let’s first see what is similar in both.

• Both are used to throw exception in catch block to log message
• Both contains same message of exception

Difference:

Now let’s see what is difference.

·         throw is used to throw current exception while throw(ex) mostly used to create a wrapper of exception.

• throw(ex) will reset your stack trace

                            I.        so error will appear from the line where throw(ex) written

                         II.        while throw does not reset stack trace and you will get information about original exception.

• In MSIL code when you use throw(ex) it will generate code as throw and if you use throw it will create re throw.

Notes: throw will get information about original exception point line no 13 as well as line where throw ex written

·         if you write main catch (Exception ex) at the top the in .net other you cannot write it’s show a compile time error to you
