如何获得指定ip的 MAC 地址

[色郎中]

public static string GetNetCardAddress2(string strIp)
{
string mac = "";

System.Diagnostics.Process process = new System.Diagnostics.Process();
process.StartInfo.FileName = "nbtstat";
process.StartInfo.Arguments = "-a "+strIp;
process.StartInfo.UseShellExecute = false;
process.StartInfo.CreateNoWindow = true;
process.StartInfo.RedirectStandardOutput = true;

process.Start();

string output = process.StandardOutput.ReadToEnd();
int length = output.IndexOf("MAC Address = ");

if(length>0)
{
mac = output.Substring(length+14, 17);
}

process.WaitForExit();

return mac.Replace("-", "").Trim();
}

这种方法 只能获得本机器的MAC
有啥更好的办法么？
谢谢

return macinfo;


这个想得到的是 字节 数组 该如何？

用C#编写获取远程IP,MAC的方法

如果要想获得远程的地址，需要用sendarp这个函数来实现。具体的代码如下：
[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ip
Int32 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();
}
}

你查一下命令行执行

执行 ipconfig /all

分析返回字符串
