loading images to ram

[mraj]

Hello...

I am new to C#. My requirement is that, I will receive over 100s of images
from the network to local machine and display these images on an image viewer
one by one on mouse scroll. To improve the performance, I want these images
to reside on the RAM instead of the hard disk. How do I load the images to
the ram and access it to improve my performance.

Just load them into an image component and cache them. Or if you are doing the drawing directly, you
can store them in byte arrays or streams.

See the GDI+ FAQ for articles that may help you to understand the
shortcomings of such a scheme.

Images take up a lot of space so uless you're using thumbnails you could be
in for a lot of pain trying to store large amounts of images in RAM.

Hi mraj,
As your goal is performance, you must keep an open eye on the number of
images and total size you are going to load in memory first.

If you think you plan it well, you can use the BitMap class to load the
Image from file and you can combine in with MemoryStream object to direct it
in a memory stream of bytes.

Mu advice to not load them all in memory, at least load couples of them and
drop them to get a new couple when user scrolls a page.

Hope that work with you, good luck
