C# Mono 程序在 raspberry pi 自动执行时崩溃

C# Mono program crashes on raspberry pi when auto executed

我们有一个 C# mono 程序 运行ning on a raspberry pi 3. 当我手动执行时程序完全执行,即 sudo mono /pathtoexe 但是当它在重启时执行从 rc.local(rc.local 启动脚本文件 sudo /pathto .sh 文件,该文件又通过 sudo mono /paththexe 启动应用程序)程序仅部分执行,日志中没有可见错误。

请注意,我们试图克服的测试用例是让我们的应用程序 运行 在没有互联网的情况下运行,因为如果有互联网(手动和自动启动)

PI是Raspberry PI3运行ningRaspbianVersion 8 (Jessie) Mono JIT 编译器版本 3.2.8 (Debian 3.2.8+dfsg-10)

这是 rc.local 文件:

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

# Print the IP address
_IP=$(hostname -I) || true
if [ "$_IP" ]; then
  printf "My IP address is %s\n" "$_IP"
fi
#echo ds1307 0x68 > /sys/class/i2c-adapter/i2c-1/new_device

#sudo mono  /home/pi/Vbox/Vbox.exe
#sudo python /home/pi/Audio/audio_play.py
#iptables-restore < /etc/iptables.ipv4.nat
exit 0

这里要注意的主线是 须藤 /home/pi/Vbox/./Main.sh&

Main.sh 文件是:

#!/bin/bash

    echo "Error:  Program"
    printf "$Datetime: Error executing $ErrorIn program. Sending E-Mail notification \n">>$ErrorLogPath
    echo "Error: notification"
    #sudo mono --runtime=v4.0 /home/pi/EXE/Email.exe &

echo "Started"

    ## Executing Gateway Core

    )} ||

}

##Master Call

当程序通过脚本执行时,日志停止于此:

Function: Main Started
73574f
Vbox Version 1.0.0.0
ERROR: ConnectMQTT - Exception connecting to the broker

代码中的主要函数如下:

static void Main()
        {
            try
            {
                Thread.Sleep(5000);
                Helper.WriteLine("Function: Main Started");

                const string path = "/home/pi/Vbox/vboxid.txt";
                VboxId = File.ReadAllText(path);
                Console.WriteLine(VboxId);
                Version = $"{Assembly.GetExecutingAssembly().GetName().Version}";
                Helper.WriteLine($"Vbox Version {Version}");
                CommMqttClient = null;

                if (string.IsNullOrEmpty(VboxId)) return;

                MQTT.ConnectMqtt(); //This is last error printed in the log shown above. The program seems to crash after this

                Task.Factory.StartNew(VideoStorage.StartStorage);

                Audio = new AudioPublicAnnouncement();
                LiveStreaming = new VideoStreaming();
                VideoRetrieve = new VideoRetrieve();

                Console.ReadLine();

            }
            catch (Exception e)
            {
                Helper.WriteLine("Error - Main: " + e.Message, ConsoleColor.Red);
            }
        }

在上面的代码中,如果手动执行程序,则可以。这是我面临的主要问题..

请注意,这是以前的代码维护者编写的,我被带进来解决这个问题。他目前不可用,过去 3 天我一直在努力解决这个问题。任何帮助将不胜感激。

谢谢, Va运行

编辑:具有不停止执行的无限循环的最新代码:

 static void Main()
        {
            try
            {
                Thread.Sleep(5000);
                Helper.WriteLine("Function: Main Started");

                const string path = "/home/pi/Vbox/vboxid.txt";
                VboxId = File.ReadAllText(path);
                Console.WriteLine(VboxId);
                Version = $"{Assembly.GetExecutingAssembly().GetName().Version}";
                Helper.WriteLine($"Vbox Version {Version}");
                CommMqttClient = null;

                if (string.IsNullOrEmpty(VboxId)) return;   

                MQTT.ConnectMqtt();

                Task.Factory.StartNew(delegate
                {
                    MQTT.PublishMessage("REBOOT", $"VBOXID:{VboxId};VERSION:{Version};TIME:{DateTime.Now:dd-MM-yyyy HH-mm-ss};", false);
                });

                Task.Factory.StartNew(VideoStorage.StartStorage);

                Audio = new AudioPublicAnnouncement();
                LiveStreaming = new VideoStreaming();
                VideoRetrieve = new VideoRetrieve();

                while (true)
                {
                    Thread.Sleep(1000);
                }
            }
            catch (Exception e)
            {
                Helper.WriteLine("Error - Main: " + e.Message, ConsoleColor.Red);
            }
        }

我将此问题标记为已解决。不幸的是,它与代码的执行方式有关。详细信息在问题的最后编辑中。 @knocte 是的,我们需要尽快执行此操作,但由于它是一个跨越 500 多个站点的生产系统 运行,我们需要对其采取经过计算和计划的方法。 感谢您的所有投入。非常感激。干杯!
