Use API functions in C#

[Le, Thanh-Nhan]

Hi,
How can I use API functions in C#.
Is there in VS .Net any simple Way to use, declare an API Function?

Thanks

Unfortunately for the most part you will have to make use of Platform Invoke
(PInvoke) while marshaling your types. This is a very broad topic. To help
you I have posted a few links below to hopefully aid you in this process.

Good Luck

Accessing unmanaged code from the .net can be done either through COM
interop or using p/invoke. P/invoke is what you need when dealing with
windows API. It basically involves a special declarations in your c#
code where you will specify a function name, library where it comes
through, and its calling signiture in c#. The hardest part is to get the
signitures and various struct layout declarations right so that the
calls from c# are marshalled right to unmanaged world. The most
excellent source for all this is pinvoke wiki:

I love this site and you can just find the windows API function that you
want to use and they will give you a c# decl for it. Not all of the
functions have examples, but once you get better, you can post examples
there too because the site is wiki.
