Can you give an example of a situation where the IDisposable pattern is used for resource management?

The IDisposable pattern is used for managing unmanaged resources such as file handles, network connections, streams, etc. Its purpose is to ensure the release of resources when the object is no longer needed.

Example: working with a file. The FileStream class implements IDisposable to close the file and release the handle after use.

using (var stream = new FileStream("file.txt", FileMode.Open))
{
    // Working with the file
}
// Here, stream.Dispose() is called automatically, and the file is closed

Using the using statement guarantees that Dispose is called even if an exception occurs.
