How to create memory file?

Arish rivlin

I cannot find a way to do that in C#... gave MemoryMappedFile a try, File is written to disk as well. I'm looking for a solution to write only to disk....

You need to create a file on Hard drive? Use methods from the built in classes of .net framework (File and Stream writer)

Hi, thanks... I need the file to be in memory and not on hard drive....

Use a MemoryStream :) Works the same like writing to disk.

What type of file? And for what will it be used? Have a look at System.IO.MemoryStream

True, but I have to avoid the disk writings, that I cannot do...

I would like to place a pointer in a mapped memory file for all dll's share... It has to be in memmory for preformance rather then on disk...

The MemoryStream won't write to a file. That is, until your memory is full and Windows starts swapping to disk. You're gonna read/write a lot from several places in a single datastore? You've probably already tried it, but I still want to suggest the use of a database. There are some data-driven websites out there, serving lots o' people at once.. This site is one of them :) --Edit-- Removed some typo's..

You would have to use the Windows API to use a Memory Mapped File and potentially unsafe code. However, I believe that the FileStream class uses the Memory Mapped File under the scenes.
