如何以编程方式在 Windows 操作系统中打开“网络发现”？

Question

我的项目使用 UPnP 协议打开端口。 Windows 默认禁用 UPnP 设备发现，需要在网络和共享中心中开启网络发现才能启用 UPnP 设备发现。

有没有办法以编程方式做到这一点？

Answer 1

您可以使用 cmd 命令来启用网络发现

netsh firewall set service type = upnp mode = mode

然后将该命令作为参数提供给代码

public void ExecuteCommandSync(object command)
{
  try
  {
    // create the ProcessStartInfo using "cmd" as the program to be run,
    // and "/c " as the parameters.
    // Incidentally, /c tells cmd that we want it to execute the command that follows,
    // and then exit.
    System.Diagnostics.ProcessStartInfo procStartInfo =
      new System.Diagnostics.ProcessStartInfo("cmd", "/c " + command);

    // The following commands are needed to redirect the standard output.
    // This means that it will be redirected to the Process.StandardOutput StreamReader.
    procStartInfo.RedirectStandardOutput = true;
    procStartInfo.UseShellExecute = false;
    // Do not create the black window.
    procStartInfo.CreateNoWindow = true;
    // Now we create a process, assign its ProcessStartInfo and start it
    System.Diagnostics.Process proc = new System.Diagnostics.Process();
    proc.StartInfo = procStartInfo;
    proc.Start();
    // Get the output into a string
    string result = proc.StandardOutput.ReadToEnd();
    // Display the command output.
    Console.WriteLine(result);
  }
  catch (Exception objException)
  {
    // Log the exception
  }
}

如果该命令不起作用，请根据您的系统查找另一个启用网络发现的命令。
