方法很多，有簡有煩，這裡選擇了個麻煩的。
主要代碼：
private void getxx(){
RegistryKey start = Registry.LocalMachine;
RegistryKey cardServiceName, networkKey;
string networkcardKey ="SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkCards";
string serviceKey = "SYSTEM\CurrentControlSet\Services\";
string networkcardKeyName, deviceName;
string deviceServiceName, serviceName;
RegistryKey serviceNames = start.OpenSubKey(networkcardKey);
if (serviceNames == null)
{
MessageBox.Show("Bad registry key");
return;
}
string[] networkCards = serviceNames.GetSubKeyNames();
serviceNames.Close();
foreach(string keyName in networkCards)
{
networkcardKeyName = networkcardKey + "\" + keyName;
cardServiceName = start.OpenSubKey(networkcardKeyName);
if (cardServiceName == null)
{
MessageBox.Show(networkcardKeyName);
return;
}
deviceServiceName =(string)cardServiceName.GetValue("ServiceName");
deviceName = (string)cardServiceName.GetValue("Description");
MessageBox.Show( deviceName);
serviceName = serviceKey + deviceServiceName + "\Parameters\Tcpip";
networkKey = start.OpenSubKey(serviceName);
if (networkKey == null)
{
。。。。。。
}
else
{
string[] ipaddresses =(string[])networkKey.GetValue("IPAddress");
string[] defaultGateways =(string[])networkKey.GetValue("DefaultGateway");
string[] subnetmasks =(string[])networkKey.GetValue("SubnetMask");
foreach(string ipaddress in ipaddresses)
{
MessageBox.Show( ipaddress);
}
foreach(string subnetmask in subnetmasks)
{
。。。。。。}
foreach(string defaultGateway in defaultGateways)
{
MessageBox.Show(defaultGateway);
}
networkKey.Close();
}
}
start.Close();
}
