C# Threading Example: ThreadPriority

Certainly! Here’s an example of how you can use the ThreadPriority enumeration in C# to set the priority of threads:

using System;
using System.Threading;

class Program
    static void Main()
        // Create two threads with different priorities
        Thread t1 = new Thread(DoWork);
        Thread t2 = new Thread(DoWork);
        t1.Priority = ThreadPriority.AboveNormal;
        t2.Priority = ThreadPriority.BelowNormal;
        // Start the threads
        // Wait for the threads to finish
        Console.WriteLine("All threads have finished.");

    static void DoWork()
        // Simulate some work
        for (int i = 0; i < 5; i++)
            Console.WriteLine($"Thread {Thread.CurrentThread.ManagedThreadId} is running.");

In this example, we create two threads t1 and t2 and assign them different priorities using the Priority property of the Thread class. t1 is given an AboveNormal priority, while t2 is given a BelowNormal priority.

The DoWork method is a simple method that simulates some work by printing a message to the console and then sleeping for 500 milliseconds. Each thread executes this method, and we can observe the impact of their priorities on their execution.

When you run the program, you will notice that the thread with the higher priority (t1) tends to get more execution time compared to the thread with the lower priority (t2). However, it’s important to note that thread priority is not a strict guarantee, and the actual behavior may vary depending on the underlying system and other factors.

Remember to add the using System.Threading; statement at the top of your file to access the ThreadPriority enumeration.
