The following small series for everyone to bring an article WinForm C # get the MAC address, IP address, subnet mask, the default gateway instance. Small series feel very good, now share to everyone, also for everyone to make a reference. Let's take a look at it with a little knitting.
1. Add an assembly
2. Introduce namespaces
Using System.Management;
3. Methods

In the B/s structure of the system, we often need to obtain some information on the client, such as IP and Mac, in conjunction with authentication. Getting a server-side Mac is easy, but getting the client's MAC address takes a lot of effort, usually by calling Win32API or calling the nbtstat command directly, which has many problems, and the other way is to use
This is the first Mac OS app development Study, Hope is a good start.First, why to learn Mac OS app developmentA) for a long time to do iOS development, found that their own limitations on some of Apple's libraries, some of the underlying API is private, not conducive to their understanding of the operating system, learning Mac OS can increase the understanding o
In the local area network, how to get the MAC address of the PPPoE server is a headache, especially in the Windows environment; There are two ways to get the PPPoE server MAC address:1. Under Windows, we run the Wireshark software, we can get all the packet format and conten
Originally just for the Mac platform to simply call fopen, fwrite and other functions, found that fopen need to include an absolute path to normal use, otherwise, even if you can create a file during debugging, directly call the app execution, the file will not be created.To do this, you need to get an absolute path to the execution file. Use the function _nsgetexecutablepath. The path that this function ob
Get Client IP:
private String Getclientip (){string result = httpcontext.current.request.servervariables["http_x_forwarded_for"];if (Null = result | | = result = String.Empty){result = httpcontext.current.request.servervariables["REMOTE_ADDR"];}
if (Null = result | | = result = String.Empty){result = HttpContext.Current.Request.UserHostAddress;}return result;}
Get MAC
The looks up several methods and, after debugging, is a good way to get a local IP and MAC address. Can be used in this aspect of the functional implementation. The main is to add a system.management reference.
Using System;
Using System.Management;
Using System.Net;
public class Program {static void Main (string[] args) {try {
string ip = "";
String
Client | source code
This procedure belongs to a special method. The scope of use is relatively limited, and there is a certain risk. Borrowed from the ASP in the back door of some methods. The following is the program code.
Dim remoteaddr
If Request.ServerVariables ("Http_x_forwarded_for") =empty Then
Remoteaddr=request.servervariables ("REMOTE_ADDR")
Else
Remoteaddr=request.servervariables ("Http_x_forwarded_for")
End If
Response.Write (Getmac (REMOTEADDR))
' Due to read the NIC
The MAC system is hidden from the user's resource file (library) by default. However, this file is often needed for many times. For some users who are not familiar with the command, it is necessary to display it. Often encountered finding a file cannot be found, but it does exist. For example, I need to find the Android configuration file, Sdk,gradle, etc., when the command view in the user's directory there is a library folder, but open the user dire
