How to implement degree of parallelism in C#

Here is an example of how to implement the right degree of parallelism in C# using the Task Parallel Library (TPL):

Define the task: Start by defining the task that needs to be executed in parallel.

void Main()

{

    List<int> numbers = Enumerable.Range(1, 100).ToList();

Divide the task: Divide the task into smaller, independent subtasks that can be executed simultaneously.

    int chunkSize = numbers.Count / 4; // 4 subtasks

Create tasks: Create a task for each subtask using the Task class.

    var tasks = new List<Task>();

    for (int i = 0; i < 4; i++)

    {

        int start = i * chunkSize;

        int end = (i + 1) * chunkSize - 1;

        tasks.Add(Task.Run(() => ProcessNumbers(numbers, start, end)));

    }

Wait for tasks to complete: Wait for all tasks to complete using the Task.WaitAll method.

    Task.WaitAll(tasks.ToArray());

}

Implement the subtask: Implement the subtask that will be executed by each task.

void ProcessNumbers(List<int> numbers, int start, int end)

{

    for (int i = start; i <= end; i++)

    {

        // Perform some processing on the numbers

    }

}

In this example, the task is divided into 4 subtasks, and 4 tasks are created to execute each subtask in parallel. The degree of parallelism is set to 4, which means 4 subtasks will be executed simultaneously. The Task. WaitAll method is used to wait for all tasks to complete before moving on to the next step.

By using the TPL, you can easily implement the right degree of parallelism in C# and achieve efficient processing times.

Understanding the Having Clause in LINQ

Language Integrated Query (LINQ) is a powerful technology in the Microsoft .NET framework that enables you to perform queries against various data sources in a unified manner. The Having clause is an important part of LINQ that allows you to filter the result of a grouped collection based on specific conditions. In this article, we'll take a closer look at the Having clause, how it works, and how you can use it in your LINQ queries. What is the Having Clause? The Having clause is used in conjunction with the GroupBy operator to filter the result of a grouped collection based on specific conditions. It's similar to the Where clause, but it operates on groups of data rather than individual elements.  The Having clause allows you to filter the groups based on aggregate values, such as group count, sum, or average, and only return the groups that meet a specific condition. For example, suppose you have a collection of numbers, and you want to group the numbers based on whether the...

Understanding Collection Types in C#: Generic and Non-generic Collections

Introduction: C# provides a wide range of collection classes that can be used to store and manage data efficiently. There are two main categories of collections in C#: generic collections and non-generic collections. In this blog, we will explore both types of collections and understand their benefits, use cases, and when to use them. Generic Collections:  Generic collections are type-safe, meaning they can only store elements of the specified data type. This ensures that the collection is free from runtime type-casting errors. Examples of generic collections in C# are ` List<T> `, ` Dictionary<TKey, TValue> `, and ` Queue<T> `. The " <T> " in these collections represents the type of elements they can store. Benefits of using Generic Collections: Type Safety : By specifying the data type of the elements, generic collections ensure that only elements of that type can be stored in the collection. This makes the code more readable and reduces the chances ...

Why Do We Use MSMQ in Applications?

MSMQ, or Microsoft Message Queue, is a message-oriented middleware system that has been around for over two decades. MSMQ is designed to enable communication and data exchange between applications, particularly in asynchronous and disconnected scenarios. In this blog, we will explore why MSMQ is used and how it can benefit your application. Guaranteed Message Delivery One of the most important features of MSMQ is guaranteed message delivery. MSMQ ensures that messages sent from one application to another are delivered, even if the recipient is temporarily unavailable. This means that messages are stored in a queue until the recipient is able to receive them, which is particularly useful in situations where network connectivity is unpredictable. Guaranteed Order of Delivery Another important feature of MSMQ is the guaranteed order of delivery. MSMQ ensures that messages are delivered in the order they were sent, even if they are delivered at different times. This is important in situati...
