通过交叉线程设置 3 个不同标签的多个值 c# winforms

Question

所以我得到了一些在 USB 连接事件上运行的代码。如果检测到 android 设备，它会运行一些与 build prop 相关的代码。然而......它只设法 return android 版本，没有别的。代码如下。

        private void Main_Shown(object sender, EventArgs e)
    {
        var watcher = new ManagementEventWatcher();
        var query = new WqlEventQuery("SELECT * FROM Win32_DeviceChangeEvent WHERE EventType = 2");
        watcher.EventArrived += new EventArrivedEventHandler(watcher_EventArrived);
        watcher.Query = query;
        watcher.Start();
    }

    private void watcher_EventArrived(object sender, EventArrivedEventArgs e)
    {   
        Process process = new System.Diagnostics.Process();
        ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
        startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
        startInfo.RedirectStandardInput = false;
        startInfo.CreateNoWindow = true;
        startInfo.RedirectStandardOutput = true;
        startInfo.RedirectStandardError = false;
        startInfo.UseShellExecute = false;
        startInfo.FileName = "adb.exe";
        startInfo.Arguments = "shell getprop ro.build.version.release";
        process = Process.Start(startInfo);
        device.Invoke((MethodInvoker)(() => device.Text = process.StandardOutput.ReadToEnd()));

        Process p = new System.Diagnostics.Process();
        ProcessStartInfo si = new System.Diagnostics.ProcessStartInfo();
        si.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
        si.RedirectStandardInput = false;
        si.CreateNoWindow = true;
        si.RedirectStandardOutput = true;
        si.RedirectStandardError = false;
        si.UseShellExecute = false;
        si.FileName = "adb.exe";
        si.Arguments = "shell getprop ro.product.model";
        p = Process.Start(si);
        AV.Invoke((MethodInvoker)(() => AV.Text = process.StandardOutput.ReadToEnd()));

        Process pr = new System.Diagnostics.Process();
        ProcessStartInfo siy = new System.Diagnostics.ProcessStartInfo();
        siy.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
        siy.RedirectStandardInput = false;
        siy.CreateNoWindow = true;
        siy.RedirectStandardOutput = true;
        siy.RedirectStandardError = false;
        siy.UseShellExecute = false;
        siy.FileName = "adb.exe";
        siy.Arguments = "shell getprop ro.product.name";
        pr = Process.Start(siy);
        name.Invoke((MethodInvoker)(() => name.Text = process.StandardOutput.ReadToEnd()));

这应该是 returning 3 个值并将它们放入相应的标签中。但是只有一个是 returned。有什么办法可以改进代码来做到这一点？ shell getprop ro.* 在较早的版本中工作并且没有被更改...

原来我是个傻逼。我为所有内容设置了相同的流程，但它引发了错误。真的是菜鸟错误。我太沉迷于自己的炒作了…… 新代码

                Process process = new System.Diagnostics.Process();
            ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
            startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
            startInfo.RedirectStandardInput = false;
            startInfo.CreateNoWindow = true;
            startInfo.RedirectStandardOutput = true;
            startInfo.RedirectStandardError = false;
            startInfo.UseShellExecute = false;
            startInfo.FileName = "adb.exe";
            startInfo.Arguments = "shell getprop ro.build.version.release";
            process = Process.Start(startInfo);
            device.Invoke((MethodInvoker)(() => device.Text = process.StandardOutput.ReadToEnd()));

            Process p = new System.Diagnostics.Process();
            ProcessStartInfo si = new System.Diagnostics.ProcessStartInfo();
            si.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
            si.RedirectStandardInput = false;
            si.CreateNoWindow = true;
            si.RedirectStandardOutput = true;
            si.RedirectStandardError = false;
            si.UseShellExecute = false;
            si.FileName = "adb.exe";
            si.Arguments = "shell getprop ro.product.model";
            p = Process.Start(si);
            AV.Invoke((MethodInvoker)(() => AV.Text = p.StandardOutput.ReadToEnd()));

            Process pr = new System.Diagnostics.Process();
            ProcessStartInfo siy = new System.Diagnostics.ProcessStartInfo();
            siy.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
            siy.RedirectStandardInput = false;
            siy.CreateNoWindow = true;
            siy.RedirectStandardOutput = true;
            siy.RedirectStandardError = false;
            siy.UseShellExecute = false;
            siy.FileName = "adb.exe";
            siy.Arguments = "shell getprop ro.product.name";
            pr = Process.Start(siy);
            name.Invoke((MethodInvoker)(() => name.Text = pr.StandardOutput.ReadToEnd()));
