C#中调用命令行cmd开启wifi热点的实例代码_C#教程

分享到:

要点1:cmd命令行的输入命令
netsh wlan set hostednetwork mode=allow ssid=用户名  key=密码
netsh wlan start hostednetwork
netsh waln stop hostednetwork
netsh interface ip set address name="本地连接" source=dhcp


要点2:在C#中调用cmd.exe命令行


       private void create(string str)
        {
            //process用于调用外部程序
            System.Diagnostics.Process p = new System.Diagnostics.Process();
            //调用cmd.exe
            p.StartInfo.FileName = "cmd.exe";
            //是否指定操作系统外壳进程启动程序
            p.StartInfo.UseShellExecute = false;
            //可能接受来自调用程序的输入信息
            //重定向标准输入
            p.StartInfo.RedirectStandardInput = true;
            //重定向标准输出
            p.StartInfo.RedirectStandardOutput = true;
            //重定向错误输出
            p.StartInfo.RedirectStandardError = true;
            //不显示程序窗口
            p.StartInfo.CreateNoWindow = true;
            //启动程序
            p.Start();
            //睡眠1s。
            System.Threading.Thread.Sleep(1000);
            //输入命令
            p.StandardInput.WriteLine(str);
            //一定要关闭。
            p.StandardInput.WriteLine("exit");
        }

            string password = textBox2.Text;
            if (password.Length >= 8 && userName != null)

            DialogResult result = MessageBox.Show(str1,"自动连接IP",
                MessageBoxButtons.OKCancel,MessageBoxIcon.Information);
            if (result == DialogResult.OK)
