Memory leaks occur when allocated memory remains unused due to certain reasons during program execution. This leads to increasing memory consumption as the program runs, potentially causing slowdowns or crashes. Even though C# .NET has a garbage collector (GC) to manage memory, certain situations can still result in memory leaks. This article will use examples to explore several common memory leak scenarios and their applications, along with testing methods.
1. Unsubscribed Event Subscriptions
Application Scenarios
In .NET, events are a mechanism for inter-object communication. If a subscriber object subscribes to an event of a publisher object but doesn’t unsubscribe when no longer needed, the publisher will continue to hold a reference to the subscriber, preventing the subscriber object from being garbage collected.
Example
// Define an event publisher class
public class EventPublisher
{
// Declare an event using the EventHandler<EventArgs> delegate, where the event data type is EventArgs
public event EventHandler<EventArgs> MyEvent;
// Method to trigger the event…
