When Should You Force Garbage Collection in C#?

C# Garbage Collection: The pros and cons of forced collection

It is generally accepted that forcing garbage collection in C# can hurt performance. However, when dealing with large objects, these objects may not be collected in the initial generation, causing memory issues.

So, in this case, is it advisable to force garbage collection manually? If so, what are the best practices?

Best Practice: Avoid Forced Garbage Collection

The recommended best practice is still to avoid manually triggering garbage collection. As Microsoft's MSDN documentation states: "In most cases, this operation should be avoided as it may cause performance issues."

Exceptions and Notes

If thorough testing confirms that calling Collect() does not negatively impact performance, then it is worth considering. Here are some additional considerations:

• Proper object cleanup: Make sure to clean up objects as soon as they are no longer needed.
• Use "using statement" and IDisposable: Implement "using statement" and IDisposable interface for custom objects to handle cleanup efficiently.
