public string GetMac()
{
try
{
ManagementObjectSearcher query = new ManagementObjectSearcher("SELECT * FROM Win32_NetworkAdapterConfiguration");

获取平板mac地址:

命名空间：

using System.Net;
using System.Runtime.InteropServices;

添加变量：
复制代码 代码如下:
protected static string strJavaScript = string.Empty;
[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);

复制代码 代码如下:
private void SetMac()
{
try
{
string treatment_id = Hid_treatment_id.Value;
string mac = string.Empty;

string ip = Request.UserHostAddress.ToString().Trim();
try
{
mac = getMac();
}
catch { lbl.InnerText = "w33w"; }
//mac = "00:01:36:D8:9C:C4";
// lbl.InnerText = mac + "," + ip;
if (mac != "您没有联网")
{
int iRetn = commonws.GetInt("CRRT/PAD-登录", "指定某治疗病人的平板MAC地址", new string[] { mac, treatment_id });
}
}
catch { lbl.InnerText = "ww"; }
}

private string getMac()
{
string mac = "";
string strClientIP = Request.UserHostAddress.ToString().Trim();
Int32 ldest = inet_addr(strClientIP); //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);
mac = macinfo.ToString("X");
try
{
string[] arr_mac = new string[mac.Length / 2];
int k = 0;
for (int i = mac.Length; i > 0; i = i - 2)
{
arr_mac[k] = mac.Substring(i - 2, 2);
k++;
}
mac = "";
foreach (string chars in arr_mac)
{
mac += chars + ":";
}
mac = mac.TrimEnd(':');
}
catch { }
return mac;
