生活工作中经常通过远程控制某台电脑，但是有些时候，我们想远程某个电脑却发现，电脑被断电或者关机了，此时必须的跑去开个机；
由各种百度，博客发现可以通过幻包远程进行唤醒：其电脑设置步骤此处省略，百度搜索远程唤醒即可找到，当然网上也有很多工具可以远程唤醒，由于楼主是学C#故发一下
远程唤醒的C#代码实现：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Sockets;
using System.Text;
using System.Threading.Tasks;
namespace Gaofajin.Shell
{
public class RemoteOpenComputer
{
public string OpenComputer(string Mac)
{
string msg = "(同网段)执行代码成功!数据包:";
try
{
byte[] packet = GetPacket(Mac);
UdpClient udpClient = new UdpClient();
udpClient.Connect(IPAddress.Broadcast,30000);
udpClient.Send(packet,packet.Length);
foreach (byte bt in packet)
{
msg += bt.ToString();
}
}catch(Exception ex)
{
msg=ex.Message;
}
return msg;
}
public string OpenComputer(string broadcastip,string mac)
{
string msg = "(不同网段)执行代码成功!数据包为：";
try
{
byte[] ip = IPToBytes(broadcastip);
byte[] packet = GetPacket(mac);
IPAddress iPAddress = new IPAddress(ip);
UdpClient udpClient = new UdpClient();
udpClient.Connect(iPAddress,30000);
udpClient.Send(packet,packet.Length);
foreach(byte bt in packet)
{
msg += bt.ToString();
}
}
catch(Exception ex)
{
msg=ex.Message;
}
return msg;
}
Func<string,byte[]> IPToBytes = ip =>
{
byte[] bts = new byte[4];
for(int i = 0;i<ip.Split('.').Length;i++)
{
bts[i]=byte.Parse(ip.Split('.')[i]);
}
return bts;
};
Func<string,byte[]> GetPacket=mac=>
{
byte[] bmac =MacTobytes(mac);
byte[] packet = new byte[17*6];
for(int i = 0;i<6;i++)
{
packet[i]=0xFF;
}
for(int j = 1;j<=16;j++)
{
for(int k = 0;k<6;k++)
{
packet[j*6+k]=bmac[k];
}
}
return packet;
};
static Func<string,byte[]> MacTobytes = mac =>
{
mac=(mac.Contains('-')) ? mac.Trim('-') : mac;
if(mac.Length!=12)
{
throw new Exception("不是有效的mac地址!");
}
byte[] bt = new byte[6];
for(int i = 0;i<6;i++)
{
bt[i]=Convert.ToByte(mac.Substring(i*2,2),16);
Console.Write(bt[i].ToString());
}
return bt;
};
}
}
