1.获取MAC地址操作:
1
using System;
2 using System.Runtime.InteropServices;
3
4 namespace UtilityControl
5
{
6
/**//// <summary>
7
/// 关于IP地址的若干操作
8
/// </summary>
9 public class IP
10 {
11 public IP()
12 {
13 //
14 // TODO: 在此处添加构造函数逻辑
15 //
16 }
17
18 [DllImport("Iphlpapi.dll")]
19 private static extern int SendARP(Int32 dest,Int32 host,ref Int64 mac,ref Int32 length);
20 [DllImport("Ws2_32.dll")]
21 private static extern Int32 inet_addr(string ip);
22
23 /**//// <summary>
24 /// 根据ip得到网卡mac地址
25 /// </summary>
26 /// <param name="ip">给出的ip地址</param>
27 /// <returns>对应ip的网卡mac地址</returns>
28 public static Int64 GetMACByIP(string ip)
29 {
30 Int32 ldest= inet_addr(ip); //目的地的ip
31 try
32 {
33 Int64 macinfo = new Int64();
34 Int32 len = 6;
35 int res = SendARP(ldest,0, ref macinfo, ref len);
36 return macinfo;
37 }
38 catch(Exception err)
39 {
40 Console.WriteLine("Error:{0}",err.Message);
41 }
42 return 0;
43 }
44 }
45
}
-----------------------------------------------------------------
用C#编写获取远程IP,MAC的方法
1[DllImport("Iphlpapi.dll")]
2private static unsafe extern int SendARP(Int32 dest,Int32 host,ref IntPtr mac,ref IntPtr length);
3[DllImport("Ws2_32.dll")]
4private static extern Int32 inet_addr(string ip);
5
6Int32 ldest= inet_addr("157.60.68.163");//目的地的ip
7Int32 lhost= inet_addr("157.60.68.33");//本地的ip
8
9try
10{
11Byte[] macinfo=new Byte[6];
12Int32 length=6;
13
14IntPtr mac=new IntPtr(macinfo[0]);
15IntPtr len=new IntPtr(6);
16int ii=SendARP(ldest,lhost, ref mac, ref len);
17
18Console.WriteLine("Mac Add:"+mac);
19Console.WriteLine("length:"+len);
20
21
22}
23catch(Exception err)
24{
25Console.WriteLine(err);
26}
27
用WMI
使用时首先添加System.Management.dll，然后引用
1using System.Management;
2using System.Threading;
3 {
4 ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
5 ManagementObjectCollection moc = mc.GetInstances();
6 foreach(ManagementObject mo in moc)
7 {
8 if((bool)mo["IPEnabled"] == true)
9 Response.Write("MAC address"+mo["MacAddress"].ToString()+"<br/>");
10 mo.Dispose();
11 }
12 }
2.手动设置IP或设置动态IP
如果是winform的话，需要添加对System.Management.dll的引用
然后使用下面的类就可以实现你的前2个要求：
1namespace modify
2{
3 public class ChangeIP
4 {
5
6 public static readonly System.Version myVersion = new System.Version(1, 1);
7 private ManagementBaseObject iObj = null;
8 private ManagementBaseObject oObj = null;
9 private ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
10 private readonly ManagementObjectCollection moc;
11
12 /**//// <summary>
13 /// example:
14 /// <code>
15 /// ArLi.CommonPrj.ChangeIP o = new ArLi.CommonPrj.ChangeIP();
16 /// string[] ipList = new string[]{"192.168.0.253","192.168.0.250"};
17 /// string[] subnetList = new string[]{"255.255.255.0","255.255.255.0"};
18 /// o.ChangeTo(ipList,subnetList);
19 /// </code>
20 /// </summary>
21 public ChangeIP()
22 {
23 moc = mc.GetInstances();
24 }
25
26 /**//// <summary>cortrol</summary>
27 /// <param name="ipAddr">IPAddr List</param>
28 /// <param name="subnetMask">subnetMask List</param>
29 public void ChangeTo(string[] ipAddr, string[] subnetMask)
30 {
31 foreach (ManagementObject mo in moc)
32 {
33 if (!(bool)mo["IPEnabled"]) continue;
34
35 iObj = mo.GetMethodParameters("EnableStatic");
36 iObj["IPAddress"] = ipAddr;
37 iObj["SubnetMask"] = subnetMask;
38 oObj = mo.InvokeMethod("EnableStatic", iObj, null);
39 }
40 }

59 iObj["DefaultIPGateway"] = gateways;
60 iObj["GatewayCostMetric"] = gatewayCostMetric;
61 oObj = mo.InvokeMethod("SetGateways", iObj, null);
62 }
63 }
64

90 iObj["DNSServerSearchOrder"] = dnsServer;
91 oObj = mo.InvokeMethod("SetDNSServerSearchOrder", iObj, null);
92 }
93 }
94
95 /**//// <summary> DHCPEnabled</summary>
96 public void EnableDHCP()
97 {
98 foreach (ManagementObject mo in moc)
99 {
100 if (!(bool)mo["IPEnabled"]) continue;
