Differentiate between finalize blocks and finalize. | C# interview Questions 18

Finalize Method:

Used for cleanup before garbage collection.
Called by the garbage collector.
Unreliable for timely cleanup.
finally Block:

Used in exception handling to ensure cleanup code runs.
Always executed after try/catch blocks.
Ensures deterministic cleanup.

Finalize Method:

A method in C# used to perform cleanup operations before an object is reclaimed by garbage collection.
Defined using a destructor syntax (~ClassName).
Called by the garbage collector, not by application code.
Unreliable for deterministic cleanup as it depends on the garbage collector’s timing.
finally Block:

Part of exception handling in C#.
Used to execute code regardless of whether an exception is thrown, ensuring that cleanup code runs.
Always executed after the try and catch blocks.
Used for deterministic cleanup, like closing files or releasing resources.
Key Differences:

Purpose: finalize (destructor) is for cleanup during garbage collection; finally is for cleanup during exception handling.
Execution Timing: finalize is called by the garbage collector at an undetermined time; finally is executed immediately after try/catch blocks.
Control: finalize is out of direct control and not guaranteed to run promptly; finally is guaranteed to run as part of the exception handling flow.
