When working with unmanaged resources (e.g., file handles, database connections), implementing IDisposable ensures they are properly released. Here's how you can do it in 3 steps:
Step 1: Implement IDisposable Interface
public class ResourceHandler : IDisposable { private bool disposed = false; // Example: Unmanaged resource private IntPtr unmanagedResource; public ResourceHandler() { // Initialize resource unmanagedResource = // allocate unmanaged resource; } // Dispose method for cleaning up resources public void Dispose() { Dispose(true); GC.SuppressFinalize(this); } protected virtual void Dispose(bool disposing) { if (!disposed) { if (disposing) { // Release managed resources here if any } // Release unmanaged resources here if (unmanagedResource != IntPtr.Zero) { // Free the unmanaged resource unmanagedResource = IntPtr.Zero; } disposed = true; } } } Step 2: Use using Statement to Automatically Call Dispose()
using (var handler = new ResourceHandler()) { // Work with the resource } Step 3: Ensure Proper Cleanup with Finalizer (if needed)
~ResourceHandler() { Dispose(false); } 📌 Highlights:
Step 1: Implement IDisposable and handle cleanup logic for both managed and unmanaged resources.
Step 2: Use the using statement for automatic resource cleanup.
Step 3: Add a finalizer if needed to ensure resources are released if Dispose is not called.
This ensures that resources are properly managed, avoiding potential memory leaks and resource exhaustion.
