Assert sınıfına HasElements işlevini ekleyelim. Bu işlev, bir koleksiyonun belirli öğelere sahip olup olmadığını kontrol eder.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading;

// ... önceki exception sınıfları ...

public class AssertHasElementsFailedException : AssertFailedException
{
    public AssertHasElementsFailedException(IEnumerable<object> missingElements)
        : base($"Expected collection to contain {string.Join(", ", missingElements)}, but it did not.") { }
}

public static class Assert
{
    // ... önceki metodlar ...

    public static void HasElements<T>(IEnumerable<T> collection, params T[] elements)
    {
        var missingElements = elements.Except(collection).ToList();

        if (missingElements.Any())
        {
            throw new AssertHasElementsFailedException(missingElements.Cast<object>());
        }
    }

    // ... diğer metodlar ...
}

HasElements metodu sayesinde, bir koleksiyonun belirli öğelere sahip olup olmadığını kontrol edebilirsiniz.

The SemaphoreSlim Class: Multitask-Based Programming in C#

2023-06-11 | #net #semaphoreslim

Overview The SemaphoreSlim class is a structure used in C# to control one or more threads using a specific resource or operation concurrently. SemaphoreSlim limits the number of threads that can access the resource at the same time. The use of SemaphoreSlim is often used to prevent deadlock situations in multi-threaded applications and to ensure that a specific resource is used by only one or more threads at the same time.

LINQ and Optimistic Concurrency: Methods for Ensuring Data Integrity

2023-06-11 | #linq #net #optimistic-concurrency

When working with databases, it is of great importance to properly manage concurrent operations and ensure data integrity. Concurrency control is used to manage multiple users or processes accessing the same data concurrently. In this article, we will explore how to ensure data integrity using LINQ (Language Integrated Query) with optimistic concurrency. What is Optimistic Concurrency? Optimistic concurrency is a method where resources are not locked when a transaction begins, but changes are checked before the transaction is completed.

When working with databases, managing concurrent operations and ensuring data integrity are of great importance. Concurrency control is used to manage multiple users or processes accessing the same data concurrently. In this article, we will explore how to use LINQ (Language Integrated Query) with pessimistic concurrency to maintain data integrity. What is Pessimistic Concurrency? Pessimistic concurrency is based on the principle of locking the relevant data when a transaction begins and maintaining the lock until the transaction is completed.
