Handling Exceptions During Image Saving: MemoryStream and Bitmap Interaction

Saving images created from memory streams can sometimes lead to exceptions if the stream is prematurely closed. This article clarifies the correct handling of MemoryStream and Bitmap objects to prevent these errors.

A MemoryStream can remain open without causing problems. The exception arises when the stream is closed while the associated Bitmap is still in use. This is because the Bitmap constructor takes ownership of the stream.

The constructor documentation explicitly states that the stream must stay open for the duration of the Bitmap's existence. Therefore, manually closing the MemoryStream is not only unnecessary but also problematic.

The solution is to focus on properly disposing of the Bitmap object. Disposing of the Bitmap will automatically close the underlying MemoryStream. This simple step effectively prevents the exception.
