How to save/store file/images in virtual memory/cache but not in disk?

Hi,

you can use MemoryStream and fileStream Class Object for this purpose. for example, using memorystream

MemoryStream ms = new MemoryStream(); //Declare Memory Stream

pictureBox1.Image.Save(ms, ImageFormat.Jpeg); // Store image from picture Box to memory Stream in JPEG format

byte[] photo_aray = new byte[ms.Length]; // if you want to read image from MemoryStream

ms.Position = 0;

ms.Read(photo_aray, 0, photo_aray.Length);
