C Multithreaded Parameter and Task Usage Example

This paper illustrates the usage of C # multithreading parameters and tasks. Share it for your reference, as follows:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading;
namespace ConsoleSample
{
  class Program
  {
    static void Main(string[] args)
    {
      Console.WriteLine(" This is the main thread ");
      DateTime dtStart = DateTime.Now;
      for (int i = 0; i < 100; i++)
      {
        Student s = new Student();
        s.name = " Zhang 3" + i;
        s.sex = " Male ";
        s.age = 28;
        Thread t = new Thread(ThreadWithParas);
        t.Start(s); // To pass data to threads, you need a class or structure that stores data 
      }
      DateTime dtEnd = DateTime.Now;
      TimeSpan span = (TimeSpan)(dtEnd - dtStart);
      Console.ReadLine();
      Console.WriteLine(" Running time  " + span.Milliseconds);
      Console.ReadLine();
    }
    static void ThreadWithParas(object o)
    {
      Student s = o as Student;
      Console.WriteLine(" This is a split thread " + Thread.CurrentThread.ManagedThreadId + " " + s.name + "---" + s.sex + "---" + s.age);
    }
  }
  public class Student
  {
    public string name;
    public string sex;
    public int age;
  }
}

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading;
using System.Threading.Tasks;
namespace ConsoleSample
{
  class Program
  {
    static void Main(string[] args)
    {
      // Task hierarchy 
      Task parent = new Task(ParentTask);
      parent.Start();
      Thread.Sleep(2000);
      Console.WriteLine(parent.Status);
      Thread.Sleep(4000);
      Console.WriteLine(parent.Status);
      Console.ReadLine();
    }
    // Parent task 
    static void ParentTask()
    {
      Console.WriteLine("task id {0}", Task.CurrentId);
      Task child = new Task(ChildTask); // , TaskCreationOptions.DetachedFromParent);
      child.Start();
      Thread.Sleep(1000);
      Console.WriteLine("parent started child");
      // Thread.Sleep(3000);
    }
    // Subtask 
    static void ChildTask()
    {
      Console.WriteLine("child");
      Thread.Sleep(5000);
      Console.WriteLine("child finished");
    }
  }
}
