Remote enable by Mac address C # (Wake On Lan)
In this article I would like to share a little experience of remotely turning on the computer. This topic is probably well known to many, but I would like to once again pay attention to this technology. I will divide my article into two parts:
This is how the created program looks like:
So, we proceed to the implementation of the first paragraph.
Currently, there are many programs that implement this item. In this article I will write a sample code that will perform the task.
')
Create a new project in Visual Studio WPF C #. To begin with, we will create the main element - this is a ListView, where the obtained information will be displayed.
XAML code
C # code
The next step is to find out your IP address and proceed to scanning the local network. The code is simple, even for a beginner, it will not cause any special difficulties.
C # code
Now we have everything we need. We proceed to the next stage.
You can read the definition here . This stage, as you understand, will only work with the computer turned off, so we will need to save all the information. I will write the full code at the end of the article.
The code is actually not that terrible, the activity of this item can be divided into two stages: the creation of a package and its sending.
C # code
That's probably all, I tried to run through the main points of the simple, but very interesting program. For the article, I filled this program with some more functionality to somehow diversify it. If someone is interested in - there is something to take for yourself. Below is the entire code:
- Scanning the local network, obtaining an IP address, HostName, Mac-address;
- Creating a " magic packet " and sending.
This is how the created program looks like:
So, we proceed to the implementation of the first paragraph.
1. LAN Scan: Obtaining an IP Address, HostName, Mac-address
Currently, there are many programs that implement this item. In this article I will write a sample code that will perform the task.

Create a new project in Visual Studio WPF C #. To begin with, we will create the main element - this is a ListView, where the obtained information will be displayed.
XAML code
<ListView Margin="12,84,12,12" Name="listView1"> <ListView.ContextMenu> <ContextMenu > <MenuItem Header=""> <MenuItem Header="IP-adress" Name="copyIP" Click="copyIP_Click" /> <MenuItem Header="HostName" Name="copyName" Click="copyName_Click" /> <MenuItem Header="Mac-adress" Name="copyMacAddress" Click="copyMacAddress_Click" /> </MenuItem> <MenuItem Header=" " Name="ClearList" Click="ClearList_Click" /> <MenuItem Header=" "/> <MenuItem Header=""> <MenuItem Header=" " Name="PowerOn" Click="PowerOn_Click" /> <MenuItem Header=" " IsEnabled="False" /> </MenuItem> <MenuItem Header=""/> </ContextMenu> </ListView.ContextMenu> <ListView.View> <GridView> <GridView.Columns> <GridViewColumn Header="IP-" DisplayMemberBinding="{Binding Path=ipAdress}" Width="200"></GridViewColumn> <GridViewColumn Header="HostName" DisplayMemberBinding="{Binding Path=nameComputer}" Width="250"></GridViewColumn> <GridViewColumn Header="Mac " DisplayMemberBinding="{Binding Path=MacAdress}" Width="250"></GridViewColumn> </GridView.Columns> </GridView> </ListView.View> </ListView> C # code
class TableHost { public string ipAdress { get; set; } public string nameComputer { get; set; } public string MacAdress { get; set; } } The next step is to find out your IP address and proceed to scanning the local network. The code is simple, even for a beginner, it will not cause any special difficulties.
C # code
// ip-. System.Net.IPAddress ip = System.Net.Dns.GetHostByName(host).AddressList[0]; private void button2_Click(object sender, RoutedEventArgs e) { int i = int.Parse(ipToString[0]); int j = int.Parse(ipToString[1]); { for(int k = 0;k<6;k++) { for (int m = 0; m < 254; m++) { // Thread _thread = new Thread(() => GetInform(string.Format("{0}.{1}.{2}.{3}", i.ToString(), j.ToString(), k.ToString(), m.ToString()))); _thread.Start(); } } } } private void GetInform(string textName) { string IP_Address = ""; string HostName = ""; string MacAddress = ""; try { // IP entry = Dns.GetHostEntry(textName); foreach (IPAddress a in entry.AddressList) { IP_Address = a.ToString(); break; } // HostName HostName = entry.HostName; // Mac-address IPAddress dst = IPAddress.Parse(textName); byte[] macAddr = new byte[6]; uint macAddrLen = (uint)macAddr.Length; if (SendARP(BitConverter.ToInt32(dst.GetAddressBytes(), 0), 0, macAddr, ref macAddrLen) != 0) throw new InvalidOperationException("SendARP failed."); string[] str = new string[(int)macAddrLen]; for (int i = 0; i < macAddrLen; i++) str[i] = macAddr[i].ToString("x2"); MacAddress = string.Join(":", str); //, , , ListView Dispatcher.Invoke(new Action(() => { _host.Add(new TableHost() { ipAdress = IP_Address, nameComputer = HostName, MacAdress = MacAddress }); listView1.ItemsSource = null; listView1.ItemsSource = _host; })); } catch { } } Now we have everything we need. We proceed to the next stage.
2. Creating “magic packet” and sending
You can read the definition here . This stage, as you understand, will only work with the computer turned off, so we will need to save all the information. I will write the full code at the end of the article.
The code is actually not that terrible, the activity of this item can be divided into two stages: the creation of a package and its sending.
C # code
[DllImport("iphlpapi.dll", ExactSpelling = true)] public static extern int SendARP(int destIp, int srcIP, byte[] macAddr, ref uint physicalAddrLen); private void WakeFunction(string MAC_ADDRESS) { WOLClass client = new WOLClass(); client.Connect(new IPAddress(0xffffffff), 0x2fff); client.SetClientToBrodcastMode(); int counter = 0; // byte[] bytes = new byte[1024]; // 6 0xFF for (int y = 0; y < 6; y++) bytes[counter++] = 0xFF; // MAC 16 for (int y = 0; y < 16; y++) { int i = 0; for (int z = 0; z < 6; z++) { bytes[counter++] = byte.Parse(MAC_ADDRESS.Substring(i, 2), NumberStyles.HexNumber); i += 2; } } // int reterned_value = client.Send(bytes, 1024); } public class WOLClass : UdpClient { public WOLClass() : base() { } // broadcast public void SetClientToBrodcastMode() { if (this.Active) this.Client.SetSocketOption(SocketOptionLevel.Socket,SocketOptionName.Broadcast, 0); } } That's probably all, I tried to run through the main points of the simple, but very interesting program.
