When multiple threads share a lock, lock the same time there is only one available to perform other thread is blocked to enter the queue, according to understand if the event is multi-threaded, then each event triggered by a function with the lock will be queued to wait, the more the more rows. Needed to be proved.
public class Test
{
public void Fun1()
{
Task.Factory.StartNew(() => {
while(true)
{
Excute("线程1:");
}
});
}
public void Fun2()
{
Task.Factory.StartNew(() =>
{
while(true)
{
Excute("线程2:");
}
});
}
public void Fun3()
{
Task.Factory.StartNew(() =>
{
while (true)
{
Excute("线程3:");
}
});
}
object ob = new object();
int A = 0;
public void Excute(string id)
{
lock(ob)
{
Console.WriteLine(id+A.ToString());
Thread.Sleep(2000);
A++;
}
}
}
