🛠️ Pro Tip: Implementing IDisposable for Proper Resource Management

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.
