C# 开发智能设备 怎么获取本机（PDA） 的mac地址

[mishixiaosenlin]

用VS2008 C#开发的智能设备怎么 获取智能设备的mac地址，或者什么唯一标识都行，就是获取一个PDA的唯一标识，各位大虾 帮帮忙，还有就是ＰＤＡ的系统是ｗｉｎ　ｃｅ　之前用的System.Management;　不好使，就不要说了，是能设备根本就掉不出来这个方法．

手头没得测试环境，你自己试试行不行吧。

先添加引用 OpenNetCF.Net

            string netinfo = "";
            foreach (INetworkInterface item in NetworkInterface.GetAllNetworkInterfaces())
            {
                netinfo += item.Name + "\r\n";
                netinfo += item.CurrentIpAddress + "\r\n";
                netinfo += item.GetPhysicalAddress() + "\r\n";
            }
            MessageBox.Show(netinfo);

现在调出的都是网络的东西，我想调用一个pda中唯一标识，那个属性能实现？

你可以用windows api来取得设备id

        [DllImport("coredll.dll", EntryPoint = "KernelIoControl", SetLastError = true)]
        private extern static bool KernelIoControl(Int32 IoControlCode, IntPtr InputBuffer, Int32 InputBufferSize, byte[] OutputBuffer, Int32 OutputBufferSize, ref Int32 BytesReturned);
        
        private static Int32 FILE_DEVICE_HAL = 0x00000101;
        private static Int32 IOCTL_HAL_GET_DEVICEID =
            ((FILE_DEVICE_HAL) << 16) | ((0x0) << 14)
            | ((21) << 2) | (0x0);       

        
        public string GetPDASerialNumber()
        {
            byte[] outputBuffer = new byte[256];
            Int32 outputBufferSize = outputBuffer.Length;
            Int32 bytesReturned = 0;

            bool retVal = KernelIoControl(IOCTL_HAL_GET_DEVICEID, IntPtr.Zero, 0, outputBuffer, outputBufferSize, ref bytesReturned);

            // If the request failed, exit the method now
            if (retVal == false)
            {
                return String.Empty;
            }

            Int32 presetIdOffset = BitConverter.ToInt32(outputBuffer, 4);
            Int32 platformIdOffset = BitConverter.ToInt32(outputBuffer, 0xc);
            Int32 platformIdSize = BitConverter.ToInt32(outputBuffer, 0x10);

            StringBuilder sb = new StringBuilder();
            sb.Append(String.Format(CultureInfo.InvariantCulture, "{0:X8}-{1:X4}-{2:X4}-{3:X4}-",
                BitConverter.ToInt32(outputBuffer, presetIdOffset),
                BitConverter.ToInt16(outputBuffer, presetIdOffset + 4),
                BitConverter.ToInt16(outputBuffer, presetIdOffset + 6),
                BitConverter.ToInt16(outputBuffer, presetIdOffset + 8)));

            for (int i = platformIdOffset; i < platformIdOffset + platformIdSize; i++)
            {
                sb.Append(String.Format(CultureInfo.InvariantCulture, "{0:X2}", outputBuffer[i]));
            }

            // return the device id string
            return sb.ToString();
        }

            byte[] DeviceOutput = new byte[20];
            uint SizeOut = 20;
            GetDeviceUniqueID(AppData, appDataSize, 1, DeviceOutput, out SizeOut);
            return DeviceOutput;
        }
    }

我有个项目用的是段，也是在csdn.net上找的。。。。。

这个是调用的设备的ID是吧，是唯一标识不能改变的是不是？

coredll.dll里好像没有GetDeviceUniqueID这个接口，调用不了啊~

[mishixiaosenlin]

有米有人能给一个明确的方法？
