isAlive and join()
Once started, a thread’s IsAlive property returns true, until the point where the thread ends. A thread ends when the delegate passed to the Thread’s constructor finishes executing. Once ended, a thread cannot restart.
You can wait for another thread to end by calling its Join method. Here’s an example:
Example
using System;
using System.Threading;
namespace ConsoleApplication1
{
class Program
{
static void Main()
{
Thread t = new Thread(Go);
// returns false because t(thread) not started
Console.WriteLine(t.IsAlive);
t.Start();// thread started
// returns true because t(thread) is started
Console.WriteLine(t.IsAlive);
// this thread(main) will wait for other threads(t) to finish
t.Join();
Console.WriteLine(t.IsAlive); // return false
Console.WriteLine("Thread t has ended!");
Console.Read();
}
static void Go()
{
for (int i = 0; i < 100; i++)
Console.WriteLine(i);
}
}
}
