Why We Use Finally For Managing Errors and Exception

Finally :
C# Support Another Statement Known as finally statement that can be used to handle an exception that is not caught by any of the previous catch statement , finally block can be used to handle any exception generated within a try block . It may be be added immediately after the last catch block shown as follows :
try                                                                                                      
{
  ...........
  ...........
}
finally
{
............
 ............
}

another example :

try                                                                                                      
{
  ...........
  ...........
}
catch(.........)
{
  ...........
  ..........
}
catch(.........)
{
  ...........
  ..........
}
finally
{
 ............
 ............
}

When a finally block is defined , this is guaranteed to execute , regardless of whether or not in exception is thrown , As a result , we can use it to perform certain house - keeping operation such as closing files and releasing system resource .
