Hi All,

Assume there are two systems System1 & System2. System1 - Windows XP and System2 - Linux. I have installed a WPF application in System1. User who is using the System2 will launch the WPF application thru Remote Connection with System1.

Thru WPF application, I can read the IP address and Windows Login Name for the System1 thru the following codes.

C#

private String GetIP()
        {
            string strHostName = "";
            strHostName = System.Net.Dns.GetHostName();
            IPHostEntry ipEntry = System.Net.Dns.GetHostEntry(strHostName);
            IPAddress[] addr = ipEntry.AddressList;
            return addr[0].ToString();
        }

String WinUserName_withNetwork = System.Security.Principal.WindowsIdentity.GetCurrent().Name;
String WinUserNameOnly = System.Environment.UserName;

Please help me how to read the IP address and Windows login name for System2.

Solution 1

Try this:

C#

string goog = "www.google.com";
IPAddress[] addresslist = Dns.GetHostAddresses(goog);

foreach (IPAddress theaddress in addresslist)
{
   Console.WriteLine(theaddress.ToString());
}

Solution 2

Try with Request.ServerVariables["REMOTE_ADDR"] or Request.UserHostAddress.

The Request object should be available anywhere in your ASPX page.
