Running ADB Shell commands rapidly in C# console app

问题

I'm trying to run a rapid amount of adb shell commands. Basically, i want to start adb shell, and then run a bunch of commands in rapid succession. Can I reuse a Process in some way? I'd like to just start adb shell and change the command text at runtime.

The problem is with creating a separate process for each command spins up a lot of process and eventually adb craps out on me.

    static void Main(string[] args)
    {
        const string AdbBroadcast = "shell am broadcast <my_cmd>";


        int broacastIndex = 0;
        while(true)
        {
            Console.WriteLine("Outputting " + broacastIndex);

            System.Diagnostics.Process process = new System.Diagnostics.Process();
            System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
            startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
            startInfo.FileName = "adb";
            startInfo.Arguments = AdbBroadcast;
            process.StartInfo = startInfo;
            process.Start();

            process.WaitForExit();


            Thread.Sleep(250);
            broacastIndex++;

        }

    }

When a device does not respond to shell commands issued via adb via Process, you can check the device state like follows:

    ProcessStartInfo lcmdInfo1;

    lcmdInfo1 = new ProcessStartInfo(" adb.exe ", "get-state");
    lcmdInfo1.CreateNoWindow = true;
    lcmdInfo1.RedirectStandardOutput = true;
    lcmdInfo1.RedirectStandardError = true;
    lcmdInfo1.UseShellExecute = false;

    Process cmd2 = new Process();
    cmd2.StartInfo = lcmdInfo1;

    var output = new StringBuilder();
    var error = new StringBuilder();

    cmd2.OutputDataReceived += (o, ef) => output.Append(ef.Data);
    cmd2.ErrorDataReceived += (o, ef) => error.Append(ef.Data);
    cmd2.Start();
    cmd2.BeginOutputReadLine();
    cmd2.BeginErrorReadLine();
    cmd2.WaitForExit();
    cmd2.Close();
    lresulterr1 = error.ToString();
    lresult1 = output.ToString();
    cmd2.Dispose();

    //sometimes there is an issue with a previously issued command that causes the device status to be 'Unknown'. Wait until the device status is 'device'
    while (!lresult1.Contains("device"))
    { 
        lcmdInfo1 = new ProcessStartInfo(" adb.exe ", "get-state");
        lcmdInfo1.CreateNoWindow = true;
        lcmdInfo1.RedirectStandardOutput = true;
        lcmdInfo1.RedirectStandardError = true;
        lcmdInfo1.UseShellExecute = false;

        cmd2 = new Process();
        cmd2.StartInfo = lcmdInfo1;

        output = new StringBuilder();
        error = new StringBuilder();

        cmd2.OutputDataReceived += (o, ef) => output.Append(ef.Data);
        cmd2.ErrorDataReceived += (o, ef) => error.Append(ef.Data);
        cmd2.Start();
        cmd2.BeginOutputReadLine();
        cmd2.BeginErrorReadLine();
        cmd2.WaitForExit();
        cmd2.Close();
        lresulterr1 = error.ToString();
        lresult1 = output.ToString();
        cmd2.Dispose();
    }
 //now your device is ready. Go ahead and fire off the shell commands
