In this article, we will explore how to remove duplicate elements from an array in C# using different approaches. Removing duplicates is a common programming task that helps maintain data integrity and optimize storage. What are Duplicate Elements in an Array? Duplicate elements are values that appear more than once in an array. When removing duplicates, we keep only one occurrence of each unique value, creating a new array with distinct elements. Examples Input: array = {1, 1, 2, 3, 3, 4, 4, 4, 5, 5, 6, 6} Output: array = {1, 2, 3, 4, ... Read More
The Console.WindowLeft property in C# gets or sets the leftmost position of the console window area relative to the screen buffer. This property controls the horizontal scrolling position of the console window within the buffer. Syntax Following is the syntax for using the Console.WindowLeft property − Console.WindowLeft = value; int leftPosition = Console.WindowLeft; Parameters The WindowLeft property accepts an int value representing the column position (0-based) where the left edge of the console window should be positioned within the screen buffer. Key Rules The value must be greater than ... Read More
The HybridDictionary class in C# is a specialized collection that combines the performance benefits of both ListDictionary and Hashtable. To check if a HybridDictionary has a fixed size, you can use the IsFixedSize property, which returns false for standard HybridDictionary instances since they are dynamically resizable. Syntax Following is the syntax for checking if a HybridDictionary has a fixed size − bool isFixed = hybridDictionary.IsFixedSize; HybridDictionary Properties The HybridDictionary class provides several properties to check its characteristics − IsFixedSize − Returns true if the dictionary has a fixed size; otherwise, false ...

The Finalize and Dispose methods in C# are both used for cleaning up resources, but they work differently and serve distinct purposes in memory management. Understanding their differences is crucial for proper resource management in .NET applications. Finalize Method The Finalize() method is called automatically by the Garbage Collector before an object eligible for collection is reclaimed. The Garbage Collector takes responsibility for deallocating memory for unreferenced objects. This method is called at some point after there are no longer valid references to that object in memory. The framework does not guarantee when this will happen. While ... Read More
XML is a self-describing language that provides data along with rules to identify what information it contains. The XDocument class in C# contains all the information necessary for a valid XML document, including XML declarations, processing instructions, and comments. The XDocument class is available in the System.Xml.Linq namespace and derives from XContainer, allowing it to contain child nodes. However, XDocument objects can have only one child XElement node, reflecting the XML standard that permits only one root element per document. Syntax Following is the syntax to populate XDocument from a string using XDocument.Parse() − XDocument ... Read More
The Facade design pattern provides a simplified interface to a complex subsystem. It acts as a wrapper that hides the complexity of multiple classes and their interactions behind a single, easy-to-use interface. This pattern is particularly useful when working with complex APIs, legacy systems, or when you need to provide a unified interface to a set of interfaces in a subsystem. Key Components The Facade pattern consists of the following components − Facade: The main interface that clients interact with. It delegates requests to appropriate subsystem objects. Subsystems: The complex classes that ... Read More
The UInt32.CompareTo() method in C# is used to compare the current instance to a specified object or UInt32 and returns an indication of their relative values. This method is essential for sorting operations and determining the ordering relationship between unsigned 32-bit integers. Syntax The UInt32.CompareTo() method has two overloads − public int CompareTo(object value); public int CompareTo(uint value); Parameters value (object) − An object to compare, or null. value (uint) − An unsigned integer to compare. Return Value The method returns an int that indicates the relative order of ... Read More
In C#, the LinkedList class provides the Count property to get the number of nodes contained in the LinkedList. This property returns an integer representing the total number of elements in the collection. Syntax Following is the syntax to get the count of nodes in a LinkedList − int count = linkedList.Count; Return Value The Count property returns an int value representing the number of nodes currently present in the LinkedList. LinkedList Node Count Node A Node B ... Read More
The List.Reverse() method in C# allows you to reverse the order of elements in a List. You can reverse the entire list or reverse a specific range of elements within the list. Syntax Following is the syntax for reversing the entire list − list.Reverse(); Following is the syntax for reversing a specified range of elements − list.Reverse(int index, int count); Parameters index − The zero-based starting index of the range to reverse. count − The number of elements in the range to reverse. ...

The main difference between List and IList in C# is that List is a concrete class that implements the list functionality, while IList is an interface that defines the contract for list operations. The IList interface inherits from both ICollection and IEnumerable interfaces. List and IList both represent collections of objects that can be accessed by index. They provide methods to insert, remove, search, and sort elements. The key distinction is that List is a specific implementation while IList is a contract that multiple classes can implement. Key Differences List IList ... Read More
