說下症結代碼
須要開啟 Windows Management Instrumentation辦事（默許曾經開啟），在法式中須要增長 Management援用。
重要有NetworkAdapter（保留適配器的IP地址，網關，子網掩碼，設置IP方面等 ）,NetworkAdapterUtil(重要是NetworkAdapter類的聚集 )兩個類。
在windows8 須要在app.manifest文件中
修正設置裝備擺設 <requestedExecutionLevel level="requireAdministrator" uiAccess="false" />，否則就算有治理員權限也修正不了IP地址。
1 設置IP地址的代碼。（設置IP地址，修正IP地址須要治理員權限）
/// <summary>
/// 收集適配器類
/// </summary>
public class NetworkAdapter
{
/// <summary>
/// 設置IP地址
/// </summary>
/// <param name="ip"></param>
/// <param name="submask"></param>
/// <param name="getway"></param>
/// <param name="dns"></param>
private bool SetIPAddress(string[] ip, string[] submask, string[] getway, string[] dns)
{
ManagementClass wmi = new ManagementClass("Win32_NetworkAdapterConfiguration");
ManagementObjectCollection moc = wmi.GetInstances();
ManagementBaseObject inPar = null;
ManagementBaseObject outPar = null;
string str = "";
foreach (ManagementObject mo in moc)
{
if (!(bool)mo["IPEnabled"])
continue;
if (this.NetworkInterfaceID == mo["SettingID"].ToString())
{
if (ip != null && submask != null)
{
string caption = mo["Caption"].ToString(); //描寫
inPar = mo.GetMethodParameters("EnableStatic");
inPar["IPAddress"] = ip;
inPar["SubnetMask"] = submask;
outPar = mo.InvokeMethod("EnableStatic", inPar, null);
str = outPar["returnvalue"].ToString();
return (str=="0"||str=="1")?true:false;
//獲得操作設置IP的前往值， 可依據前往值去確認IP能否設置勝利。 0或1表現勝利
// 前往值解釋網址： https://msdn.microsoft.com/en-us/library/aa393301(v=vs.85).aspx
}
if(getway!=null)
{
inPar = mo.GetMethodParameters("SetGateways");
inPar["DefaultIPGateway"] = getway;
outPar = mo.InvokeMethod("SetGateways", inPar, null);
str = outPar["returnvalue"].ToString();
return (str == "0" || str == "1") ? true : false;
}
if (dns != null)
{
inPar = mo.GetMethodParameters("SetDNSServerSearchOrder");
inPar["DNSServerSearchOrder"] = dns;
outPar = mo.InvokeMethod("SetDNSServerSearchOrder", inPar, null);
str = outPar["returnvalue"].ToString();
return (str == "0" || str == "1") ? true : false;
}
}
}
return false;
}
｝
2 設置IP為主動獲得
/// <summary>
/// 啟用DHCP辦事
/// </summary>
public void EnableDHCP()
{
ManagementClass wmi = new ManagementClass("Win32_NetworkAdapterConfiguration");
ManagementObjectCollection moc = wmi.GetInstances();
foreach (ManagementObject mo in moc)
{
if (!(bool)mo["IPEnabled"])
continue;
if (mo["SettingID"].ToString() == this.NetworkInterfaceID) //網卡接口標識能否相等, 相當只設置指定適配器IP地址
{
mo.InvokeMethod("SetDNSServerSearchOrder", null);
mo.InvokeMethod("EnableDHCP", null);
}
}
｝
3. 獲得一切適配器
public class NetworkAdapterUtil
{
/// <summary>
/// 獲得一切適配器類型，適配器被禁用則不克不及獲得到
/// </summary>
/// <returns></returns>
public List<NetworkAdapter> GetAllNetworkAdapters() //假如適配器被禁用則不克不及獲得到
{
IEnumerable<NetworkInterface> adapters = NetworkInterface.GetAllNetworkInterfaces(); //獲得一切適配器
return GetNetworkAdapters(adapters);
}
/// <summary>
/// 依據前提獲得IP地址聚集，
/// </summary>
/// <param name="adapters">收集接口地址聚集</param>
/// <param name="adapterTypes">收集銜接狀況，如,UP,DOWN等</param>
/// <returns></returns>
private List<NetworkAdapter> GetNetworkAdapters(IEnumerable<NetworkInterface> adapters, params NetworkInterfaceType[] networkInterfaceTypes)
{
adapterList = new List<NetworkAdapter>();
foreach (NetworkInterface adapter in adapters)
{
if (networkInterfaceTypes.Length <=0) //假如沒傳可選參數，就查詢一切
{
if (adapter != null)
{
NetworkAdapter adp = SetNetworkAdapterValue(adapter);
adapterList.Add(adp);
}
else
{
return null;
}
}
else //過濾查詢數據
{
foreach (NetworkInterfaceType networkInterfaceType in networkInterfaceTypes)
{
if (adapter.NetworkInterfaceType.ToString().Equals(networkInterfaceType.ToString()))
{
adapterList.Add(SetNetworkAdapterValue(adapter));
break; //加入以後輪回
}
}
}
}
return adapterList;
｝
/// <summary>
/// 設置收集適配器信息
/// </summary>
/// <param name="adapter"></param>
/// <returns></returns>
private NetworkAdapter SetNetworkAdapterValue(NetworkInterface adapter)
{
NetworkAdapter networkAdapter = new NetworkAdapter();
IPInterfaceProperties ips = adapter.GetIPProperties();
networkAdapter.Description = adapter.Name;
networkAdapter.NetworkInterfaceType = adapter.NetworkInterfaceType.ToString();
networkAdapter.Speed = adapter.Speed / 1000 / 1000 + "MB"; //速度
networkAdapter.MacAddress = adapter.GetPhysicalAddress(); //物理地址聚集
networkAdapter.NetworkInterfaceID = adapter.Id;//收集適配器標識符
networkAdapter.Getwaryes = ips.GatewayAddresses; //網關地址聚集
networkAdapter.IPAddresses = ips.UnicastAddresses; //IP地址聚集
networkAdapter.DhcpServerAddresses = ips.DhcpServerAddresses;//DHCP地址聚集
networkAdapter.IsDhcpEnabled =ips.GetIPv4Properties()==null?false: ips.GetIPv4Properties().IsDhcpEnabled; //能否啟用DHCP辦事
IPInterfaceProperties adapterProperties = adapter.GetIPProperties();//獲得IPInterfaceProperties實例
networkAdapter.DnsAddresses = adapterProperties.DnsAddresses; //獲得並顯示DNS辦事器IP地址信息 聚集
return networkAdapter;
}
}
｝
4 啟用， 禁用適配器代碼
/// <summary>
/// 啟用一切適配器
/// </summary>
/// <returns></returns>
public void EnableAllAdapters()
{
// ManagementClass wmi = new ManagementClass("Win32_NetworkAdapter");
// ManagementObjectCollection moc = wmi.GetInstances();
System.Management.ManagementObjectSearcher moc = new System.Management.ManagementObjectSearcher("Select * from Win32_NetworkAdapter where NetEnabled!=null ");
foreach (System.Management.ManagementObject mo in moc.Get())
{
//if (!(bool)mo["NetEnabled"])
// continue;
string capation = mo["Caption"].ToString();
string descrption =mo["Description"].ToString();
mo.InvokeMethod("Enable",null);
}
}
/// <summary>
/// 禁用一切適配器
/// </summary>
public void DisableAllAdapters()
{
// ManagementClass wmi = new ManagementClass("Win32_NetworkAdapter");
// ManagementObjectCollection moc = wmi.GetInstances();
System.Management.ManagementObjectSearcher moc = new System.Management.ManagementObjectSearcher("Select * from Win32_NetworkAdapter where NetEnabled!=null ");
foreach (System.Management.ManagementObject mo in moc.Get())
{
//if ((bool)mo["NetEnabled"])
// continue;
string capation = mo["Caption"].ToString();
string descrption = mo["Description"].ToString();
mo.InvokeMethod("Disable", null);
}
}
