Windows services terminating near JsonConvert.DeserializeObject

Question

Below is the code written for window services for copying files. It terminate from line "JsonConvert.DeserializeObject>(jsonStirng);"

public static void copyfiles()
{
    getLog("Before querying");
    SqlDataReader reader = select();
    if (reader.HasRows)
    {
        reader.Read();               
        string jsonStirng = reader["parameter"].ToString();
        getLog("Found rows" + jsonStirng); // this will get log with values
        try
        {

            var result = JsonConvert.DeserializeObject<List<RootObject>>(jsonStirng);
            getLog("result =>" + result[0].FOLDER_NAME); // this ignore, if remove above line, this log will work.
            // continue logic for copying files..
            }

        }
        catch (Exception e)
        {
            getLog("Fail to copy files"+e);
        }

    }
    else
    {
        getLog("No rows found.");
    }
    reader.Close();
}

Below is the log i am getting

What exception do you get? Could you please add the exception details to your question (type, message, etc.)? — bassfader, May 22 '19 at 11:56
it is not coming to catch block and even "Event Viewer" shows "Service started successfully." — Suresh Kamrushi, May 22 '19 at 11:58
Can you show us what the log output looks like? You appear to be logging data at various points -- which log entries are getting hit? — bvoyelr, May 22 '19 at 12:04
Thanks! I'm surprised that you're not getting something else in the logs. Can you provide the `RootObject` class? It should have a public, empty constructor. Also, you might try removing the `+e` from the exception log (or changing it to `e.Message`). It could be causing some other exception that is preventing that log from working (it SHOULDN'T be causing another exception, but it could be causing one). — bvoyelr, May 22 '19 at 12:14
RootObject is correct only because, tested the code in web application it is working fine. Let me change the e to e.Message — Suresh Kamrushi, May 22 '19 at 12:21
According to your log, it says "error in init windows service". Where is the code that logs that message? — Chris Dunaway, May 22 '19 at 15:21
Hi Suresh. i am having exactly the same issue.. did you find the cause? — Ansenagy, Jun 29 '19 at 17:31
@Ansenagy: Did not get solution to it. I change json to db then. — Suresh Kamrushi, Jul 01 '19 at 06:16

You can step through your service like a normal application in vs by altering the main entry point of the service.

static void Main()
{
/////IF DEBUG The service will create all resource and allow code stepthrough
#if (!DEBUG)
    //NO DEBUG - Production code ran here
    System.ServiceProcess.ServiceBase[] ServicesToRun;
    ServicesToRun = new System.ServiceProcess.ServiceBase[] { new MyService() };
    System.ServiceProcess.ServiceBase.Run(ServicesToRun);
#else
    // Debug code: this allows the process to run as a non-service.
    // It will kick off the service start point, but never kill it.
    // Shut down the debugger to exit
    MyService service = new MyService();
    service.OnStart(null);    
    System.Threading.Thread.Sleep(System.Threading.Timeout.Infinite);
#endif 
}
