C# THREAD PRIORITY
“C# thread priority is the process of setting priority for
the threads so that the can execute/perform their task as the priority
specified is known as thread priority in multithreading. “
When we perform multithreading inc# then the CPU utilize its resources equally among all the thread and give
equal time to execute that threads. Now the problem is if we have two different
methods and that are executing by two different threads but the method one has
to do more work than two in these case we can set the priority for the threads
we can give specify more CPU resources to thread one to complete its work as
compare to thread two, therefore we use thread priority in multithreading.
We have
five level of thread priority in multithreading
1. Lowest
In this the level the selected thread consumes least CPU resources as
compare to the all others to execute.
2. Below Normal
After lowest this level will came. This level consume more CPU resources
as compare to Lowest but less as compare to all others.
3. Normal
The default priority of threads when we create threads then the CPU
utilize its resources equally among the threads that is the Normal level.
4. Above Normal
It consume more resources as compare to the above four but less resources
as compare to highest level.
5. Highest
Last
and powerful level in this level the selected thread consumes the highest
resources of CPU as compare to the all others. It is used when a thread have to
work more than all thread exist in program.
Syntax
After
instantiating child thread and specify its task, we can set the priority in
such a way.
[<Th>].Priority
= ThreadPriority.
<Level>
Dot Priority = ThreadPriority. is the keyword in c# thread priority, where in place of <Th> the thread instance will come and in place
of <Level> the five level which is detailed above will placed. If the
syntax does work then try this one.
[<Th>].Priority = System.Threading.ThreadPriority. <Level>;
Sometime the compiler does not recognize only ThreadPriority so don't vary about this error use the full syntax of System. Threading .ThreadPriority and then mention level
THREAD PRIORITY EXAMPLE
Note : Don’t forget to add System. Threading
using
System.Threading;
namespace
ThreadPriority
{
class Program
{
public static void
Test()
{
for
(int a =1; a<=20; a++)
{
if
(a%2==0)
{
Console.WriteLine(+a + " is even number");
}
else
{
Console.WriteLine(+a + " is odd number");
}
}
}
public static void
Test2()
{
int
a = 1;
while(a<=50)
{
Console.WriteLine(a);
a++;
}
}
static void
Main(string[] args)
{
Thread t1 = new
Thread(Test);
Thread t2 = new
Thread(Test2);
t1.Priority =
System.Threading.ThreadPriority.Highest;
t2.Priority =
System.Threading.ThreadPriority.Lowest;
t1.Start();
t2.Start();
Console.ReadKey();
}
}
}
