发现好长时间没写技术方面的东西了，不免有些生疏了，这几天工作状态不错，随便写点东西吧。
好多用notebook的朋友比较苦恼的一个问题，在公司和在家里的网络设置不一样，于是上班和回到家的时候都要更改网卡的网络设置。
我也是比较烦这个东西，每天改来改去的很麻烦，今天心血来潮，决定写一个小程序简化一下这个步骤。
查了一下dotnet相关方面的东西和文章，发现的确可行。
using System.Management 这个里面封装了这些东东，
网卡的设置无非就是四项，IP地址，子网掩码，网关，DNS
设置四个string型变量：
private string ipaddress;
private string subcode;
private string netgate;
private string dns;
private string IpAddree
{
set
{
ipaddress=value;
}
get
{
return ipaddress;
}
}
private string SubCode
{
set
{
subcode=value;
}
get
{
return subcode;
}
}
private string NetGate
{
set
{
netgate=value;
}
get
{
return netgate;
}
}
private string Dns
{
set
{
dns=value;
}
get
{
return dns;
}
}
利用下面这个方法来更改网卡设置：
private void changeip()
{
ManagementBaseObject inPar = null;
ManagementBaseObject outPar = null;
ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
ManagementObjectCollection moc = mc.GetInstances();
//遍历所有在工作状态的网卡
foreach(ManagementObject mo in moc)
{
if(! (bool) mo["IPEnabled"])
continue;
//Set IPAddress & SubnetMask
inPar = mo.GetMethodParameters("EnableStatic");
inPar["IPAddress"] = new string[] { IpAddree };
inPar["SubnetMask"] = new string[] { SubCode };
outPar = mo.InvokeMethod("EnableStatic", inPar, null);
//set Getway
inPar = mo.GetMethodParameters("SetGateways");
inPar["DefaultIPGateway"] = new string[]{ NetGate };
outPar = mo.InvokeMethod("SetGateways", inPar, null);
//set dns
inPar = mo.GetMethodParameters("SetDNSServerSearchOrder");
inPar["DNSServerSearchOrder"] = new string[] { Dns};
outPar = mo.InvokeMethod("SetDNSServerSearchOrder", inPar, null);
}
}
就是这么简单，根据以上的办法去msdn的库里面查下相关方面的东西，网卡的大多数属性都是可以通过.net程序来更改的。

嘿嘿 现在再也不用手工更改网络设置那么麻烦了。
其实这个东西完全可以写一个config文件，功能变得更强大一点。不过最近时间比较紧，写这些东西仅仅有一个小时不到的时间
