Shared Named Memory

[Maxwell2006]

Hi,

Is there a concept of shared named memory in .NET to allow multiple program
use the name and then set/retrieve values?

Thank you,
Alan

Alan,

No, not really. You should be using remoting and a singleton for
something like this (with a named pipe channel).

Hope this helps.

You are most likely referring to MemoryMapped Files, which in done through
P/invoke to the MapViewOfFile and related APIs. You can find several good C#
implementations of this.

Why not to use Shared Property Manager (SharedProperty GroupManager,
SharedPropertyG roup, and SharedProperty) for this reason?
But it's available with the assembly System.Enterpri seServices

AFAIK there is no built-in mechanism for this...

To use shared memory you can use memory mapped files ( mmf ), where file name will be the name of the shared memory.

Well, the reason for this is because it is only really applicable for
COM+ applications. Applications outside of COM+ are not able to use it.

Thank you for help.

Do you know any sample that shows me how to use Memory Mapped files in C#?

Thank you,
