How can you guaranteedly release resources that implement IDisposable?

In C#, the using statement is used to ensure the release of resources that implement the IDisposable interface. It automatically calls the Dispose method, even if an exception occurs during the execution of the code block.

Example:

using (var resource = new SomeDisposableResource())
{
    // Work with the resource
}
// The resource has been released here (Dispose called automatically)

Alternatively, you can explicitly call Dispose in a finally block:

var resource = new SomeDisposableResource();
try
{
    // Work with the resource
}
finally
{
    resource.Dispose();
}

Using using is preferable because it makes the code cleaner and safer.
