最近看到一些对IP的操作,感觉不错,而且以后可能会用到,所以收集过来,以备以后使用.
1.获取MAC地址操作:
using System; using System.Runtime.InteropServices; namespace UtilityControl { /// <summary> /// 关于IP地址的若干操作 /// </summary> public class IP { public IP() { // // TODO: 在此处添加构造函数逻辑 // } [DllImport("Iphlpapi.dll")] private static extern int SendARP(Int32 dest,Int32 host,ref Int64 mac,ref Int32 length); [DllImport("Ws2_32.dll")] private static extern Int32 inet_addr(string ip); /// <summary> /// 根据ip得到网卡mac地址 /// </summary> /// <param name="ip">给出的ip地址</param> /// <returns>对应ip的网卡mac地址</returns> public static Int64 GetMACByIP(string ip) { Int32 ldest= inet_addr(ip); //目的地的ip try { Int64 macinfo = new Int64(); Int32 len = 6; int res = SendARP(ldest,0, ref macinfo, ref len); return macinfo; } catch(Exception err) { Console.WriteLine("Error:{0}",err.Message); } return 0; } } }
-----------------------------------------------------------------
用C#编写获取远程IP,MAC的方法
[DllImport("Iphlpapi.dll")]private static unsafe extern int SendARP(Int32 dest,Int32 host,ref IntPtr mac,ref IntPtr length);[DllImport("Ws2_32.dll")]private static extern Int32 inet_addr(string ip);
Int32 ldest= inet_addr("157.60.68.163");//目的地的ipInt32 lhost= inet_addr("157.60.68.33");//本地的ip
try{Byte[] macinfo=new Byte[6];Int32 length=6;
IntPtr mac=new IntPtr(macinfo[0]);IntPtr len=new IntPtr(6);int ii=SendARP(ldest,lhost, ref mac, ref len);
Console.WriteLine("Mac Add:"+mac);Console.WriteLine("length:"+len);
}catch(Exception err){Console.WriteLine(err);}
-----------------------------------------------
用WMI使用时首先添加System.Management.dll，然后引用using System.Management;using System.Threading; { ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration"); ManagementObjectCollection moc = mc.GetInstances(); foreach(ManagementObject mo in moc) { if((bool)mo["IPEnabled"] == true) Response.Write("MAC address"+mo["MacAddress"].ToString()+"<br/>"); mo.Dispose(); } }
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：namespace modify{ public class ChangeIP {
public static readonly System.Version myVersion = new System.Version(1, 1); private ManagementBaseObject iObj = null; private ManagementBaseObject oObj = null; private ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration"); private readonly ManagementObjectCollection moc;
/// <summary> /// example: /// <code> /// ArLi.CommonPrj.ChangeIP o = new ArLi.CommonPrj.ChangeIP(); /// string[] ipList = new string[]{"192.168.0.253","192.168.0.250"}; /// string[] subnetList = new string[]{"255.255.255.0","255.255.255.0"}; /// o.ChangeTo(ipList,subnetList); /// </code> /// </summary> public ChangeIP() { moc = mc.GetInstances(); }
/// <summary>cortrol</summary> /// <param name="ipAddr">IPAddr List</param> /// <param name="subnetMask">subnetMask List</param> public void ChangeTo(string[] ipAddr, string[] subnetMask) { foreach (ManagementObject mo in moc) { if (!(bool)mo["IPEnabled"]) continue;
iObj = mo.GetMethodParameters("EnableStatic"); iObj["IPAddress"] = ipAddr; iObj["SubnetMask"] = subnetMask; oObj = mo.InvokeMethod("EnableStatic", iObj, null); } }
/// <summary>cortrol</summary> /// <param name="ipAddr">IPAddr List</param> /// <param name="subnetMask">subnetMask List</param> /// <param name="gateways">gateway List</param> /// <param name="gatewayCostMetric">gateway CostMetric List, example: 1</param> public void ChangeTo(string[] ipAddr, string[] subnetMask, string[] gateways, string[] gatewayCostMetric) { foreach (ManagementObject mo in moc) { if (!(bool)mo["IPEnabled"]) continue;
iObj = mo.GetMethodParameters("EnableStatic"); iObj["IPAddress"] = ipAddr; iObj["SubnetMask"] = subnetMask; oObj = mo.InvokeMethod("EnableStatic", iObj, null);
iObj = mo.GetMethodParameters("SetGateways"); iObj["DefaultIPGateway"] = gateways; iObj["GatewayCostMetric"] = gatewayCostMetric; oObj = mo.InvokeMethod("SetGateways", iObj, null); } }
/// <summary>cortrol</summary> /// <param name="ipAddr">IPAddr List</param> /// <param name="subnetMask">subnetMask List</param> /// <param name="gateways">gateway List</param> /// <param name="gatewayCostMetric">gateway CostMetric List, example: 1</param> /// <param name="dnsServer">DNSServer List</param> public void ChangeTo(string[] ipAddr, string[] subnetMask, string[] gateways, string[] gatewayCostMetric, string[] dnsServer) { foreach (ManagementObject mo in moc) { if (!(bool)mo["IPEnabled"]) continue;
iObj = mo.GetMethodParameters("EnableStatic"); iObj["IPAddress"] = ipAddr; iObj["SubnetMask"] = subnetMask; oObj = mo.InvokeMethod("EnableStatic", iObj, null);
iObj = mo.GetMethodParameters("SetGateways"); iObj["DefaultIPGateway"] = gateways; iObj["GatewayCostMetric"] = gatewayCostMetric; oObj = mo.InvokeMethod("SetGateways", iObj, null);
iObj = mo.GetMethodParameters("SetDNSServerSearchOrder"); iObj["DNSServerSearchOrder"] = dnsServer; oObj = mo.InvokeMethod("SetDNSServerSearchOrder", iObj, null); } }
/// <summary>DHCPEnabled</summary> public void EnableDHCP() { foreach (ManagementObject mo in moc) { if (!(bool)mo["IPEnabled"]) continue;
if (!(bool)mo["DHCPEnabled"]) { iObj = mo.GetMethodParameters("EnableDHCP"); oObj = mo.InvokeMethod("EnableDHCP", iObj, null); } } } }}
测试代码：using System.Management;using modify;namespace WindowsApplication13{ public partial class Form1 : Form { public Form1() { InitializeComponent(); //对第二个问题验证 ChangeIP test = new ChangeIP(); string[] str1 = new string[] {"192.168.1.5"}; string[] str2 = new string[] { "255.255.255.0" }; test.ChangeTo(str1, str2);
MessageBox.Show("IP已经更改，请验证");
//对第一个问题的验证，如果IP可用，当前并不是自动获取IP，这时下面的方法会自动获取IP test.EnableDHCP(); } }}
