Question

想知道实际检索IP类型的c＃代码：基于我将输入的设备列表的静态或DHCP。

要查看的输出：

Device name:  IP Address:   MAC Address:         Type:  
Marvell Yukon 88E8001/8003/8010 PCI Gigabit Ethernet Controller NULL    00:00:F3:44:C6:00   DHCP
Generic Marvell Yukon 88E8056 based Ethernet Controller 192.168.1.102   00:00:F3:44:D0:00   DHCP

            ManagementClass objMC = new ManagementClass("Win32_NetworkAdapterConfiguration");
        ManagementObjectCollection objMOC = objMC.GetInstances();

        txtLaunch.Text = ("Name\tIP Address\tMAC Address\tType" +"\r\n");

        foreach (ManagementObject objMO in objMOC)
        {
            StringBuilder builder = new StringBuilder();

            object o = objMO.GetPropertyValue("IPAddress");
            object m = objMO.GetPropertyValue("MACAddress");

            if (o != null || m != null)
            {
                builder.Append(objMO["Description"].ToString());
                builder.Append("\t");
                    if (o != null)
                       builder.Append(((string[])(objMO["IPAddress"]))[0].ToString());
                    else
                       builder.Append("NULL");
                builder.Append("\t");
                builder.Append(m.ToString());
                builder.Append("\t");
                builder.Append(Convert.ToBoolean(objMO["DHCPEnabled"]) ? "DHCP" : "Static");
                builder.Append("\r\n");
            }

            txtLaunch.Text = txtLaunch.Text + (builder.ToString());

这给了我90％的目标 - 代码效果很好。下一部分是指定网络上的设备以远程获取信息。我注意到下面的一条评论说没有WMI这是不可能的。这肯定比我更接近。我确信这可以实现。我愿意接受这里的建议。

编辑：抱歉，某些适配器上的某些属性可能为NULL。修正了

ManagementClass objMC = new ManagementClass(
                        "Win32_NetworkAdapterConfiguration");
ManagementObjectCollection objMOC = objMC.GetInstances();

Console.WriteLine("Name\tIP Address\tMAC Address\tType");

foreach (ManagementObject objMO in objMOC)
{

  StringBuilder builder = new StringBuilder();

  builder.Append(objMO["Description"].ToString());
  builder.Append("\t");
  object o = objMO.GetPropertyValue("IPAddress");

  if (o != null)
      builder.Append(((string[])(objMO["IPAddress"]))[0].ToString());
  else
      builder.Append("NULL");

  builder.Append("\t");

  object m = objMO.GetPropertyValue("MACAddress");

  if (m != null)
      builder.Append(m.ToString());
  else
      builder.Append("NULL");

  builder.Append("\t");
  builder.Append(Convert.ToBoolean(objMO["DHCPEnabled"]) ? "DHCP" : "Static");
  Console.WriteLine(builder.ToString());
}

Answer 3

~~如果您尝试为远程主机执行此操作，则无法执行此操作。您需要访问DHCP服务器及其日志记录以识别此信息。~~

编辑：当然，如果可以的话，通过WMI工作。

C＃轮询多个设备以确定IP类型：静态或DHCP
