说下关键代码
需要开启 windows management instrumentation服务（默认已经开启），在程序中需要增加 management引用。
主要有networkadapter（保存适配器的ip地址，网关，子网掩码，设置ip方面等 ）,networkadapterutil(主要是networkadapter类的集合 )两个类。
在windows8 需要在app.manifest文件中
修改配置 <requestedexecutionlevel level="requireadministrator" uiaccess="false" />，不然就算有管理员权限也修改不了ip地址。
1 设置ip地址的代码。（设置ip地址，修改ip地址需要管理员权限）
我要评论
/// <summary>
/// 网络适配器类
/// </summary>
public class networkadapter
{
/// <summary>
/// 设置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(); //描述
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;
//获取操作设置ip的返回值， 可根据返回值去确认ip是否设置成功。 0或1表示成功
// 返回值说明网址： 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 设置ip为自动获取
/// <summary>
/// 启用dhcp服务
/// </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) //网卡接口标识是否相等, 相当只设置指定适配器ip地址
{
mo.invokemethod("setdnsserversearchorder", null);
mo.invokemethod("enabledhcp", null);
}
}
｝
3. 获取所有适配器
public class networkadapterutil
{
/// <summary>
/// 获取所有适配器类型，适配器被禁用则不能获取到
/// </summary>
/// <returns></returns>
public list<networkadapter> getallnetworkadapters() //如果适配器被禁用则不能获取到
{
ienumerable<networkinterface> adapters = networkinterface.getallnetworkinterfaces(); //得到所有适配器
return getnetworkadapters(adapters);
}
/// <summary>
/// 根据条件获取ip地址集合，
/// </summary>
/// <param name="adapters">网络接口地址集合</param>
/// <param name="adaptertypes">网络连接状态，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) //如果没传可选参数，就查询所有
{
if (adapter != null)
{
networkadapter adp = setnetworkadaptervalue(adapter);
adapterlist.add(adp);
}
else
{
return null;
}
}
else //过滤查询数据
{
foreach (networkinterfacetype networkinterfacetype in networkinterfacetypes)
{
if (adapter.networkinterfacetype.tostring().equals(networkinterfacetype.tostring()))
{
adapterlist.add(setnetworkadaptervalue(adapter));
break; //退出当前循环
}
}
}
}
return adapterlist;
｝
/// <summary>
/// 设置网络适配器信息
/// </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(); //物理地址集合
networkadapter.networkinterfaceid = adapter.id;//网络适配器标识符
networkadapter.getwaryes = ips.gatewayaddresses; //网关地址集合
networkadapter.ipaddresses = ips.unicastaddresses; //ip地址集合
networkadapter.dhcpserveraddresses = ips.dhcpserveraddresses;//dhcp地址集合
networkadapter.isdhcpenabled =ips.getipv4properties()==null?false: ips.getipv4properties().isdhcpenabled; //是否启用dhcp服务
ipinterfaceproperties adapterproperties = adapter.getipproperties();//获取ipinterfaceproperties实例
networkadapter.dnsaddresses = adapterproperties.dnsaddresses; //获取并显示dns服务器ip地址信息 集合
return networkadapter;
}
}
｝
4 启用， 禁用适配器代码
/// <summary>
/// 启用所有适配器
/// </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>
/// 禁用所有适配器
/// </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);
}
}
