Getting client ip address

[Andy]

Hi all,

I'm trying to write some code in a business layer which will audit the
IP address that the request is coming from.

If the business layer is being called from a web app, I'd like to get
the IP address of the client browser, but if the business layer is
being called from a desktop app, i'd like to capture the desktop's IP
address.

The catch is that I don't want to have to pass the IP address from the
UI layer into the business layer; the business layer should be able to
detect this automatically.

Any ideas?

Thanks
Andy

Dns.Resolve(Dns.GetHostName()).AddressList
This will return all the IP addresses of the machine. I don't know how to
get it from a browser, it's the wrong group for that.

Cheers,

I know how to get it from a browser, so i guess the question is
technically how do i detect if i'm running an IIS process or not, and
if i am running under one, how can i get the HttpContext object.

Andy,

You can do this by checking the static Current property on the
HttpContext class. If there is one, then you will be able to get it here.

However, if you are going to use these objects through remoting, I don't
know that it would be possible to actually get the IP address of the client.
You should have your client objects get the IP address yourself, and then
pass that long with the call.

Hope this helps.
