Find Own IP

Can anyone give me a pointer how can I use C# to enumerate or find out the IP address of the machine the code is running on?

Thanks much

Hi!

If you are using C# for your ASP .NET application you can definately do something like...

Code:

string ip = Page.Request.ServerVariables["LOCAL_ADDR"];

In order to see all the keys in the collection you can do something like this

Code:

NameValueCollection variables = Page.Request.ServerVariables;
string[] keys = variables.AllKeys;
for(int i = 0; i < keys.Length; i++)
   Page.Response.Write(keys[i] + "<BR>");

I don't know too much about .NET applications. I am only doing ASP .NET in C#, so the above goes for ASP .NET.

Jacob,

Thanks for your reply. Unfortunately, I do want to use this as a part of a console utility... So if anyone has any idea how to enum the local IP address/s, that would be great.

Thanks again

Try this code and extend it if you need to

IPHostEntry LocalHost = Dns.GetHostByName("");
LocalHost.AddressList[0].ToString();

The requiered classes are defined in System.Net
namespace.
