Why use finally C #?

In C #, what is the point of having a sentence finally?

eg.

try {
        // do something
    }
catch (Exception exc)
    {
        // do something
    }
// do something

Will the code work at the end? What is the block point finally?

Good, except when the application is killed at the system level or the computer explodes.

The code in the finally block is always executed regardless of whether an exception is thrown or not. Code following the exception block may or may not be executed if the path is returned in catch.
