What are some common memory leak scenarios in C#?

What are some common memory leak scenarios in C#?

Common memory leak scenarios in C# include:

1. Event handlers not being unsubscribed.
2. Static references holding onto objects.
3. Long-lived collections that grow indefinitely.
4. Unmanaged resources not being released properly.

Can you explain how event handlers can cause memory leaks?

Sure! If an event handler is attached to an event but not unsubscribed when the object is no longer needed, it keeps a reference to that object, preventing it from being garbage collected.

What can I do to prevent these memory leaks?

To prevent memory leaks, always unsubscribe from events when they are no longer needed, use weak references if appropriate, and regularly review your code for static references.

Are there any tools to help identify memory leaks in C#?

Yes, tools like .NET Memory Profiler, ANTS Memory Profiler, and Visual Studio's built-in diagnostic tools can help identify memory leaks.
