Set the user accounts in Task Scheduler through C#

Question

I am trying to set the following options in Task Scheduler using my C# program.

1. In settings tab of Task scheduler, check the box "If the task fails, restart every 1 minute"
2. In General tab of Task scheduler, under security options, set it to "BigDataService" for "When running the task, use the following user account" and provide its password.

My current code looks like this:

 using (TaskService ts = new TaskService())
 {
    TaskDefinition td = ts.NewTask();
    TimeTrigger trigger = new TimeTrigger();
    var startTime = TimeSpan.Parse(section1["ScheduledTime"]);
    trigger.StartBoundary = DateTime.Today + startTime;
    trigger.Repetition.Interval = TimeSpan.FromDays(1);
    trigger.StartBoundary = DateTime.Now;
    td.Principal.RunLevel = TaskRunLevel.Highest;
    trigger.Id = "Data";
    trigger.Repetition.Interval = TimeSpan.FromDays(1);
    td.Triggers.Add(trigger);
    td.Actions.Add(new ExecAction(@"DataUpload.exe", argument, null));
    var foldername = ts.GetFolder(@"\Bigdata");
    Console.WriteLine(foldername.Path);
    foldername.RegisterTaskDefinition(section1["JobName"], td);
}

New Cod (works fine with RegisterTaskDefinition, but when I add the RepetitionInterval line, the task does not get created in the BigData folder.

using (TaskService ts = new TaskService())
 {
    TaskDefinition td = ts.NewTask();
    TimeTrigger trigger = new TimeTrigger();
    var startTime = TimeSpan.Parse(section1["ScheduledTime"]);
    trigger.StartBoundary = DateTime.Today + startTime;
    trigger.Repetition.Interval = TimeSpan.FromDays(1);
    trigger.StartBoundary = DateTime.Now;
    td.Principal.RunLevel = TaskRunLevel.Highest;
    trigger.Id = "Data";
    trigger.Repetition.Interval = TimeSpan.FromDays(1);
    td.Triggers.Add(trigger);
    td.Actions.Add(new ExecAction(@"DataUpload.exe", argument, null));
    var foldername = ts.GetFolder(@"\Bigdata");
    Console.WriteLine(foldername.Path);   
    foldername.RegisterTaskDefinition(section1["JobName"], td, TaskCreation.CreateOrUpdate,"Bigdataservice", "password");
}

@xDaevax: This is my current code. I am not sure what should I add to my current code for the two settings. — user3447653, Jul 06 '16 at 18:26

To set restart Interval to 1 minute:

td.Settings.RestartInterval = TimeSpan.FromMinutes(1);

To set the login:

td.Principal.LogonType = TaskLogonType.Group;
// Pass the credentials when you register the task
foldername.RegisterTaskDefinition(section1["JobName"], td,
    TaskCreation.CreateOrUpdate, "DOMAIN\\USERNAME", "Pas$w0rD");

RegisterTaskDefinition works fine. When I add the RestartInterval, the task does not get created in the appropriate folder. I have added the new code in the question. – user3447653 Jul 06 '16 at 19:54
Try removing the slash from the foldername – leetibbett Jul 06 '16 at 19:59
