What is the IDisposable interface in C#?

The IDisposable interface is used to release unmanaged resources in C#. It provides a method called Dispose.

Why is it important to implement IDisposable?

Implementing IDisposable is crucial for managing resources efficiently, especially when dealing with file handles or database connections.

Can you give me an example of how to implement it?

Sure! Here's a simple example:

public class MyClass : 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 happens if I forget to call Dispose?

Forgetting to call Dispose can lead to resource leaks, as unmanaged resources won't be released until the garbage collector finalizes the object, which can impact performance.
