asp.net如何获取客户端网卡mac地址?
asp.net如何获取客户端网卡mac地址?
下面的这种只能取到服务器端的!
ManagementClass mc = new ManagementClass( "Win32_NetworkAdapterConfiguration ");
ManagementObjectCollection moc2 = mc.GetInstances();
foreach (ManagementObject mo in moc2)
{
if ((bool)mo[ "IPEnabled "] == true)
v_localUnique = mo[ "MacAddress "].ToString();
mo.Dispose();
}
下面这种也不行
string mac= " ";
Process process=new Process();
process.StartInfo.FileName= "nbtstat ";
string ip = Request.UserHostAddress.ToString();
process.StartInfo.Arguments = "-a " + ip;
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);
}
不知是我用错了,还是其它的什么问题!望大家教教我!

//添加组件System.Management
using System.Management;
using System.Runtime.InteropServices;
[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);
protected void Page_Load(object sender, EventArgs e)
{
try
{
string userip = Request.UserHostAddress;
Int32 ldest = inet_addr(userip); //目的地的ip
Int32 lhost = inet_addr( " "); //本地服务器的ip
Int64 macinfo = new Int64();
Int32 len = 6;
int res = SendARP(ldest, 0, ref macinfo, ref len);
string mac_src = macinfo.ToString( "X ");
if (mac_src == "0 ")
{
if (userip == "127.0.0.1 ")
userinfo.Text = "正在访问Localhost! ";
else
userinfo.Text = "欢迎来自IP为 " + userip + "的朋友！ ";
return;
}
while (mac_src.Length < 12)
{
mac_src = mac_src.Insert(0, "0 ");
}
string mac_dest = " ";
for (int i = 0; i < 11; i++)
{
if (0 == (i % 2))
mac_dest = mac_dest.Insert(0, mac_src.Substring(i, 2));
}
userinfo.Text = "欢迎来自IP为 " + userip + ",MAC地址为 " + mac_dest + "的朋友！ ";
}
catch (Exception err)
{
Response.Write(err.Message);
}
}
