What happens if both catch and finally blocks throw exception?

Question

What happens if both catch and finally blocks throw exception?

Answer 1

When the finally block throws an exception, it will effectively hide the exception thrown from the catch block and will be the one ultimately thrown. It is therefore important to either log exceptions when caught, or make sure that the finally block does not itself throw an exception, otherwise you can get exceptions being thrown that are stifled and never seen.

Answer 2

When catch throws an exception, finally block will be run and then exit with an exception. If the finally block throws an exception, the block will exit with an exception.

Answer 3

The last exception thrown is thrown.

Answer 5

HI Nwaman i think you answer is wrong i have tested it in windows appliaction, i found if u write a program like the below one

try
{
    string s = "hu";
    int i = int.Parse(s);
}
catch (Exception ex)
{
    string s = "hu";
    int i = int.Parse(s);
    throw new Exception();
}
finally
{
    MessageBox.Show("hi");
}

and this will not result finally to excute,
