c# equal to vb module

[moondaddy]

I'm writing a c# 3.0 app and want to know if there is anything similar to
the vibe module. I want to cache some data in memory for all classes to
access during the app session which will avoid having to access the data
source each time its needed. this data is mostly static for the session.
As I understand, a static class can not hold class level variables. I want
to create an instance of a class, have it read this data into class level
variables, then any class in the project can access this instance and
thereby not having to create new instances making them read from the data
source over and over again.

Is this possible?

C# does not have module.

But take a look at singleton pattern.

A static class is as close as it gets. The difference is that module
members are automatically imported to the global namespace in VB, and
they are implicitly Shared/static (whereas C# forces you to still mark
each member as static). The end result is largely the same though.

As I understand, a static class can not hold class level variables.

Only static variables.

Hi Moondaddy,

The VB.NET module come from the VB6 module which provides global shared
functions among the application. For .NET application developing through
C#, if you also want such public shared functions or variables as in VB.NET
module, you can consider define some public class with static member
variables/functions. Thus, those functions and variables can be visible and
accessible from other class code. And since they're marked as static, the
shared scope is the entire AppDomain. At runtime each AppDomain will has a
single copy of such static class variables.
