C#实现获取设置IP地址小工具

界面效果图如下：

报表界面

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）

/// <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);
}
}
