You’ll need to write your own class to do this, I found this example (pasted because it looks as though the site’s domain has lapsed):
using System.Threading;
public sealed class QueuedLock
{
private object innerLock;
private volatile int ticketsCount = 0;
private volatile int ticketToRide = 1;
public QueuedLock()
{
innerLock = new Object();
}
public void Enter()
{
int myTicket = Interlocked.Increment(ref ticketsCount);
Monitor.Enter(innerLock);
while (true)
{
if (myTicket == ticketToRide)
{
return;
}
else
{
Monitor.Wait(innerLock);
}
}
}
public void Exit()
{
Interlocked.Increment(ref ticketToRide);
Monitor.PulseAll(innerLock);
Monitor.Exit(innerLock);
}
}
Example of usage:
QueuedLock queuedLock = new QueuedLock();
try
{
queuedLock.Enter();
// here code which needs to be synchronized
// in correct order
}
finally
{
queuedLock.Exit();
}
