. NET thread Synchronization (3)

Another synchronization strategy is manual technology, which system.threading some classes in the namespace that can be used for manual synchronization. The ManualResetEvent class is used to keep a thread in a waiting state, which has 2 states: signaled (True) or no signal (False). There are 2 other important methods: Reset () and set ().

The following code illustrates the use of the Reset () method:

Using System;
Using System.Threading;

Namespace Manualreset
{

Class Reset
{

[STAThread]
static void Main ()
{
ManualResetEvent manre;
Manre=new ManualResetEvent (TRUE); Assign to the semaphore
BOOL State=manre.waitone (1000,true);
Console.WriteLine ("ManualResetEvent after the WaitOne" +state);

Manre.reset (); Set ManualResetEvent status to no semaphore
State=manre.waitone (5000,true);
Console.WriteLine ("ManualResetEvent after second WaitOne" +state);
}
}
}

Run Result:



The following code illustrates the use of the Set () method:

Using System;
Using System.Threading;
Namespace Manualset
{

Class Set
{

[STAThread]
static void Main (string[] args)
{
ManualResetEvent manre;
Manre=new ManualResetEvent (FALSE);
Console.WriteLine ("Before WaitOne");
BOOL State=manre.waitone (5000,true);
Console.WriteLine ("ManualResetEvent after the WaitOne" +state);

Manre.set (); Set its state to a semaphore
Thread.Sleep (3000);
State=manre.waitone (5000,true);
Console.WriteLine ("ManualResetEvent after second WaitOne" +state);
}
}
}

Run Result:
