Advice on Web Project for interface to another DLL

[Danny]

Hi

I'm kind of lost here.

I'm creating a ASP.NET page using C# as my code behind. I'm getting
information from the user from the ASP.NET page after the submit. The
part that I'm lost is that I want to feed this info to a DLL to run
some particular service. I'm not sure how to do that with C# ???

Also, would this scenario be handled the same way if instead of a DLL
it was another C# program?
I'm appreciate any advice. Thanks.

What kind of DLL is it? Is it a managed assembly or an old unmanaged type?

Hello,

It is possible to call functions from unmanage type DLLs using PInvoke. The
idea
is to provide C# enough information on the function (ie parameters, return
types...)

To call a simple fonction with this prototype located in test.dll

int print(int x, int y, char *name, int *error_code);

you will write :

[DllImport("test.dll")]
static extern int print(int x, int y, String name, out int error_code);

Well, this is the basic idea. It can get more complicated depending on the
function prototype :)
