A synchronized wrapper for a SortedList object provides thread-safe access to the collection in multi-threaded environments. The SortedList.Synchronized() method creates a wrapper that ensures only one thread can access the collection at a time. Syntax Following is the syntax for creating a synchronized wrapper − SortedList synchronizedList = SortedList.Synchronized(originalList); To check if a SortedList is synchronized, use the IsSynchronized property − bool isSync = sortedList.IsSynchronized; Creating a Synchronized SortedList The following example demonstrates how to create a synchronized wrapper and verify its synchronization status − using System; ...

The Singleton design pattern belongs to the Creational type pattern. It ensures that only one instance of a particular class is created throughout the application lifecycle. This single instance coordinates actions across the application and provides global access to shared resources. The Singleton pattern is useful when you need exactly one instance of a class, such as for logging, caching, thread pools, or configuration settings. Implementation Guidelines Declare all constructors as private to prevent external instantiation. Provide a static property or method that returns the single instance. Store the instance in a static field to ensure ... Read More
The ListDictionary class in C# provides a Values property that returns an ICollection containing all the values stored in the dictionary. This is useful when you need to iterate through or manipulate only the values without accessing the keys. Syntax Following is the syntax to get the values collection from a ListDictionary − ICollection values = listDictionary.Values; Return Value The Values property returns an ICollection object that contains all the values in the ListDictionary. The collection maintains the same order as the original dictionary entries. Using Values Property with Device Names ... Read More
The StringBuilder class in C# provides several constructors to create instances with different initial capacities. When you specify a capacity, you're setting the initial buffer size that StringBuilder allocates for string operations, which can improve performance by reducing memory reallocations. Syntax Following are the main constructors for creating StringBuilder with specified capacity − StringBuilder sb = new StringBuilder(int capacity); StringBuilder sb = new StringBuilder(string value, int capacity); Creating StringBuilder with Initial Capacity You can create a StringBuilder with a specific initial capacity to optimize memory usage − using System; using System.Text; ...

In C#, both classes and structures are used to define data types and hold data. While they appear similar in functionality, they have fundamental differences in how they store and manage data. Classes are reference types that provide more flexibility and advanced features, while structures are value types designed for simple data storage with better performance in certain scenarios. Understanding these differences is crucial for choosing the right type for your specific use case and writing efficient C# code. Syntax Following is the syntax for declaring a class − public class ClassName { ... Read More
C# provides three important operators for working with types: typeof, GetType(), and is. These operators allow you to examine object types at runtime, perform type checking, and enable reflection-based operations. Syntax Following is the syntax for the typeof operator − Type type = typeof(ClassName); Following is the syntax for the GetType() method − Type type = objectInstance.GetType(); Following is the syntax for the is operator − bool result = objectInstance is TargetType; Understanding typeof, GetType, and is Type Operations in C# ...

In this article, we will learn how to write a C# program that uses LINQ parallel query to generate random even numbers. LINQ (Language Integrated Query) is a powerful feature of C# that allows developers to query data from various sources using a consistent syntax. Parallel LINQ (PLINQ) extends LINQ to execute queries in parallel, improving performance for large datasets. Problem Explanation We need to create a program that generates random even numbers using LINQ parallel query. The solution involves using ParallelEnumerable.Range() to create a sequence of numbers, then applying the Where() clause to filter even numbers and ... Read More
To get an enumerator that iterates through the ListDictionary, you can use the GetEnumerator() method, which returns an IDictionaryEnumerator. This allows you to iterate through the key-value pairs in the dictionary using a while loop or foreach loop. The ListDictionary is a specialized collection class that implements a dictionary using a singly linked list, making it efficient for small collections (typically 10 or fewer elements). Syntax Following is the syntax for getting an enumerator from a ListDictionary − IDictionaryEnumerator enumerator = listDictionary.GetEnumerator(); while (enumerator.MoveNext()) { // Access enumerator.Key and enumerator.Value } ...

The BitArray class in C# implements the IEnumerable interface, which allows you to iterate through its elements using an enumerator. This enables the use of foreach loops to traverse through each bit value in the array sequentially. The enumerator returns each bit as a bool value, making it easy to process the individual bits in a BitArray collection. Syntax Following is the syntax for iterating through a BitArray using an enumerator − BitArray bitArray = new BitArray(size); IEnumerable enumerable = bitArray; foreach (Object bit in enumerable) { // Process each bit } ... Read More
The SortedDictionary class in C# provides the GetEnumerator() method to iterate through its key-value pairs. This method returns an IDictionaryEnumerator that allows you to traverse the collection in ascending order of keys. Syntax Following is the syntax for getting an enumerator from a SortedDictionary − IDictionaryEnumerator enumerator = sortedDictionary.GetEnumerator(); To iterate through the enumerator − while (enumerator.MoveNext()) { Console.WriteLine("Key = " + enumerator.Key + ", Value = " + enumerator.Value); } Return Value The GetEnumerator() method returns an IDictionaryEnumerator object that provides access to the key-value ...
