[英]How to set IP Address of Network adapters?
我必須經常更改IP地址才能玩LAN游戲以及在家中使用互聯網。 我正在C#中創建一個可以快速完成的應用程序。 我做了一些字段,例如適配器名稱,IP地址,子網,DNS服務器地址。 我的代碼在設置IP按鈕單擊時運行,如下所示:
string adapter = comboAdapterName.Text;
string ip = comboIPAddress.Text;
string subnet = comboSubnet.Text;
string dns = comboDNS.Text;
現在,我想使用此處理方法從這些字段中獲取數據並相應地附加字符串。
Process p = new Process();
ProcessStartInfo psi = new ProcessStartInfo("netsh", "interface ip set address \"Local Area Connection\" static 192.168.0.10 255.255.255.0 192.168.0.1 1");
p.StartInfo = psi;
p.Start();
但是我想這並不容易。 因為我無法在不干擾格式的情況下對其進行編輯。 我也嘗試使用許多我可以放置的+來創建一個全新的字符串:
ProcessStartInfo psi = new ProcessStartInfo(mystring);
但是對我來說仍然太難了。 請提出一種簡單的方法。
================================================== ========================
我想我明白了:
string ipstring = "netsh interface ip set address " + "\"" + adapter + "\"" + " " + "static" + " " + ip + " " + subnet + " " + dns;
您將需要使用String.Format方法。
例:
string subnet = comboSubnet.Text;
string formatted = string.Format("Subnet is: {0}", subnet);
MessageBox.Show(formatted);
格式化該字符串以使其看起來像您想要的任何內容。
您可以使用以下功能獲取當前的適配器配置:
private static void EthernetInf(out string ip, out string dns, out string nic) // To get current ethernet config
{
ip = "";
dns = "";
nic = "";
foreach (NetworkInterface ni in NetworkInterface.GetAllNetworkInterfaces())
{
if (ni.NetworkInterfaceType == NetworkInterfaceType.Ethernet)
{
foreach (IPAddress dnsAdress in ni.GetIPProperties().DnsAddresses)
{
if (dnsAdress.AddressFamily == System.Net.Sockets.AddressFamily.InterNetwork)
{
dns = dnsAdress.ToString();
}
}
foreach (UnicastIPAddressInformation ips in ni.GetIPProperties().UnicastAddresses)
{
if (ips.Address.AddressFamily == System.Net.Sockets.AddressFamily.InterNetwork && !ips.Address.ToString().StartsWith("169")) //to exclude automatic ips
{
ip = ips.Address.ToString();
nic = ni.Name;
}
}
}
}
以下功能用於在提升的命令提示符下設置IP:
private void SetIP(Button sender, string arg) //To set IP with elevated cmd prompt
{
try
{
if (sender.Background == Brushes.Cyan )
{
MessageBox.Show("Already Selected...");
return;
}
ProcessStartInfo psi = new ProcessStartInfo("cmd.exe");
psi.UseShellExecute = true;
psi.WindowStyle = ProcessWindowStyle.Hidden;
psi.Verb = "runas";
psi.Arguments = arg;
Process.Start(psi);
if (sender == EthStatic || sender == EthDHCP )
{
EthStatic.ClearValue(Button.BackgroundProperty);
EthDHCP.ClearValue(Button.BackgroundProperty);
sender.Background = Brushes.Cyan;
}
if (sender == WIFIStatic || sender == WIFIDhcp)
{
WIFIStatic.ClearValue(Button.BackgroundProperty);
WIFIDhcp.ClearValue(Button.BackgroundProperty);
sender.Background = Brushes.Cyan;
}
}
catch(Exception ex)
{
MessageBox.Show(ex.Message);
}
此單擊按鈕代碼將參數傳遞給processstartinfo來設置IP
private void EthStatic_Click(object sender, RoutedEventArgs e)
{
SetIP(EthStatic, "/c netsh interface ip set address \"" + EthName + "\" static " + Properties.Settings.Default.EthIPac + " " + Properties.Settings.Default.Subnet + " " + Properties.Settings.Default.EthDnsac + " & netsh interface ip set dns \"" + EthName + "\" static " + Properties.Settings.Default.EthDnsac);
}
