How do I properly clean up resources in C#?

How do I properly clean up resources in C#?

In C#, you can clean up resources by implementing the IDisposable interface and using the Dispose method.

Can you give me an example of using IDisposable?

Sure! Here's a simple example:

public class Resource : IDisposable {
    private bool disposed = false;

    public void Dispose() {
        Dispose(true);
        GC.SuppressFinalize(this);
    }

    protected virtual void Dispose(bool disposing) {
        if (!disposed) {
            if (disposing) {
                // free managed resources
            }
            // free unmanaged resources
            disposed = true;
        }
    }
}

What about using the 'using' statement?

The 'using' statement is a great way to ensure that resources are disposed of automatically. For example:

using (var resource = new Resource()) {
    // use resource
}
// resource is disposed of here

Are there any common mistakes to avoid?

Yes, common mistakes include forgetting to call Dispose, not implementing IDisposable correctly, and not handling exceptions during resource cleanup.
