How to create File with the FILE_ATTRIBUTE_TEMPORARY in C#?

Question

How to create File with the FILE_ATTRIBUTE_TEMPORARY in C#? (So to store Data in Ram but be able to use it as normal file)

Answer 1

I believe you'll have to use P/Invoke to call the native CreateFile then use the FileStream(SafeFileHandle, FileAccess) constructor on FileStream. MSDN has a sample for how to use SafeFileHandle and CreateFile together.

Answer 2

Memory mapped files are an alternative, and are built into C# 4.0:
