用c#更改IP.Gateway,Mask等的和对.net下调用WMI的认识(原创)

private void Ipstatic()
  {
   ManagementBaseObject inPar1  = null;
   ManagementBaseObject inPar2  = null;
   ManagementBaseObject outPar1 = null;
   ManagementBaseObject outPar2 = null;
   ManagementClass mc = new ManagementClass( "Win32_NetworkAdapterConfiguration");
   ManagementObjectCollection moc = mc.GetInstances();
   foreach( ManagementObject mo in moc )
   {
    if( !(bool)mo[ "IPEnabled" ])
     continue;
    if( mo["Caption"].Equals("[00000008] VMware Virtual Ethernet Adapter for VMnet1") )
    {
     inPar1 = mo.GetMethodParameters( "EnableStatic" );
     inPar2 = mo.GetMethodParameters( "SetGateways" );
     inPar2["DefaultIPGateway"] = new string[] { "192.168.1.1" };
     inPar2["GatewayCostMetric"] = new int[] {1};
     
     inPar1["IPAddress"] = new string[] { "192.168.1.10" };     
     inPar1["SubnetMask"] = new string[] { "255.255.255.0" };
     outPar1 = mo.InvokeMethod( "EnableStatic", inPar1, null );
     outPar2 = mo.InvokeMethod( "SetGateways", inPar2, null );
     break;
    }           
   }

此为c#版本,只能在本地执行.(不能在asp.net中使用,原因现在没还弄清楚,可能是MicroSoft在IIS设置了什么)

注意,需要导入System.Management或System.Management.Dll这个.net组件.这样才可以使用System.Management这个名字空间.

用这种方法,可以使用.net语言来调用WMI的类和接口.具体见msdn

下面再介绍一种调用WMI的方法(同时兼顾远程调用时的问题)(老外的代码,具体见

http://www.codeproject.com/csharp/wmi.asp 

//Connect to the remote computer
ConnectionOptions co = new ConnectionOptions();

co.Username = textUserID.Text;
co.Password = textPassword.Text;

//Point to machine
System.Management.ManagementScope ms = new System.Management.
    ManagementScope("" + stringHostName + "//root//cimv2", co);

(这里改成"."也可以表示本地)

//Query system for Operating System information
System.Management.ObjectQuery oq = new System.Management.ObjectQuery(
    "SELECT * FROM Win32_OperatingSystem");
ManagementObjectSearcher query = new ManagementObjectSearcher(ms,oq);

queryCollection = query.Get();
foreach ( ManagementObject mo in queryCollection)
{

   (以下代码不用看了)
    //create child node for operating system
    createChildNode(nodeCollection, "Operating System: " +
        mo["Caption"]);
    createChildNode(nodeCollection, "Version: " + mo["Version"]);
    createChildNode(nodeCollection, "Manufacturer : " +
        mo["Manufacturer"]);
    createChildNode(nodeCollection, "Computer Name : " +
        mo["csname"]);
    createChildNode(nodeCollection, "Windows Directory : " +
        mo["WindowsDirectory"]);
}     

其实ManagementClass也可以完成以上功能(用它的不同的构造函数),具体见msdn

下面是一个补充:(把查询得到的TCP/IP信息,放到asp.net中显示)

 private void Button1_Click(object sender, System.EventArgs e)
  {
   ManagementClass mc = new ManagementClass( "Win32_NetworkAdapterConfiguration");
   ManagementObjectCollection moc = mc.GetInstances();
   foreach( ManagementObject mo in moc )
   {
    if( !(bool) mo[ "IPEnabled"] )
     continue;
    if( mo["Caption"].Equals( "[00000001] ADMtek AN983 10/100 PCI Adapter" ) )
    {
     string[] addresses = ( string[] ) mo["IPAddress"];
    
     foreach( string ipadr in addresses )
     {
      IP1.Text = ipadr.ToString();
      MAC1.Text = mo["MACAddress"].ToString();
     }
    }
    if( mo["Caption"].Equals( "[00000008] VMware Virtual Ethernet Adapter for VMnet1") )
    {
     string[] addresses = ( string[] ) mo["IPAddress"];
    
     foreach( string ipadr in addresses )
     {
      IP2.Text = ipadr.ToString();
      MAC2.Text = mo["MACAddress"].ToString();
     }
    }    
   } 
  }

下面是在Console App中实现的代码:

 static void ReportIP()
  {
   Console.WriteLine( "****** Current IP addresses:" );
   ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
   ManagementObjectCollection moc = mc.GetInstances();
   foreach( ManagementObject mo in moc )
   {
    if( ! (bool) mo[ "IPEnabled" ] )
     continue;

    Console.WriteLine( "{0}//n SVC: /'{1}/' MAC: [{2}]", (string) mo["Caption"],
     (string) mo["ServiceName"], (string) mo["MACAddress"] );

    string[] addresses = (string[]) mo[ "IPAddress" ];
    string[] subnets = (string[]) mo[ "IPSubnet" ];

    Console.WriteLine( " Addresses :" );
    foreach(string sad in addresses)
     Console.WriteLine( "", sad );

    Console.WriteLine( " Subnets :" );
    foreach(string sub in subnets )
     Console.WriteLine( "

", sub );
   }
  }
