Open137920Released 1y ago100% Free### Understanding the Task The task is to demonstrate the use of tasks in C#. Specifically, I will create a code snippet that showcases the creation and execution of tasks, including proper error handling and documentation comments. ### Key Points * Create a task that performs a simple operation (e.g., calculating the square of a number) * Demonstrate how to execute the task synchronously and asynchronously * Handle potential exceptions that may occur during task execution * Adhere to best practices in C# programming, including naming conventions, documentation comments, and modular design ### Code Snippet ```csharp using System; using System.Threading.Tasks; namespace TaskDemo { /// <summary> /// Demonstrates the use of tasks in C#. /// </summary> public class TaskExample { /// <summary> /// Calculates the square of a number. /// </summary> /// <param name="number">The number to square.</param> /// <returns>The squared result.</returns> private static async Task<int> CalculateSquareAsync(int number) { try { // Simulate some work await Task.Delay(100); // Calculate the square int result = number * number; // Return the result return result; } catch (Exception ex) { // Handle the exception Console.WriteLine($"An error occurred: {ex.Message}"); throw; } } /// <summary> /// Executes the task synchronously. /// </summary> public static void ExecuteTaskSynchronously() { int number = 5; try { int result = CalculateSquareAsync(number).Result; Console.WriteLine($"Synchronous result: {result}"); } catch (AggregateException ex) { Console.WriteLine($"Synchronous error: {ex.InnerException.Message}"); } } /// <summary> /// Executes the task asynchronously. /// </summary> public static async void ExecuteTaskAsynchronously() { int number = 5; try { int result = await CalculateSquareAsync(number); Console.WriteLine($"Asynchronous result: {result}"); } catch (Exception ex) { Console.WriteLine($"Asynchronous error: {ex.Message}"); } } } class Program { static void Main(string[] args) { TaskExample.ExecuteTaskSynchronously(); TaskExample.ExecuteTaskAsynchronously(); Console.ReadLine(); } } } ``` This code snippet creates a `TaskExample` class that demonstrates the use of tasks in C#. The `CalculateSquareAsync` method calculates the square of a number and simulates some work using a delay. The method is marked as `async` to allow for asynchronous execution. The `ExecuteTaskSynchronously` method executes the task synchronously using the `Result` property, while the `ExecuteTaskAsynchronously` method executes the task asynchronously using the `await` keyword. Both methods handle potential exceptions that may occur during task execution. In the `Main` method, we call both execution methods to demonstrate the synchronous and asynchronous execution of the task. Note that this is a simple example, and in a real-world scenario, you would want to handle errors more robustly and consider using `Task.Run` or `Task.Factory.StartNew` to create tasks.
