C# 获取网关地址 读取配置文件 打开关闭exe

C#好久好久没去用过了,今早写了个C#小程序, 链接手机热点,然后根据发过来的信息去读取配置文件,将配置文件中相应的exe重启,即先关闭后启动.

里面涉及到的一些小块我在这里记录下.

1, 获取链接的手机热点的网关

//得到网关地址
private static string GetGateway()
{
string strGateway = "";

//获取所有网卡
NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();

foreach (var netWork in nics)
{
IPInterfaceProperties ip = netWork.GetIPProperties();
//获取该IP对象的网关
GatewayIPAddressInformationCollection gateways = ip.GatewayAddresses;

foreach (var gateWay in gateways)
{
if (IsPingIP(gateWay.Address.ToString()))
{
strGateway = gateWay.Address.ToString();
break;
}
}
if (strGateway.Length > 0)
{
break;
}
}
return strGateway;
}

public static bool IsPingIP(string strIP)
{
try
{
Ping ping = new Ping();
PingReply reply = ping.Send(strIP, 1000);
return true;
}
catch
{
return false;
}
}

2, 读取配置文件

[DllImport("kernel32")]
private static extern int GetPrivateProfileString(string lpAppName, string lpKeyName, string lpDefault,
StringBuilder lpReturnedString, int nSize, string lpFileName);

// 读取配置文件
private static string ReadINIString(string section, string key, string def, string filePath)
{
StringBuilder temp = new StringBuilder(1024);
try
{
GetPrivateProfileString(section, key, def, temp, 1024, filePath);
}
catch { }
return temp.ToString();
}

3.打开关闭exe

// 关闭exe
Process[] allProgresse = Process.GetProcesses();
foreach (Process closeProgress in allProgresse)
{
if (closeProgress.ProcessName.Equals(sname))
{
closeProgress.Kill();
closeProgress.WaitForExit();
break;
}
}

// 打开exe
System.Diagnostics.Process.Start(sPath);
