SByte.GetTypeCode Method in C# with Examples
The SByte.GetTypeCode() method in C# is used to return the TypeCode enumeration value for the sbyte data type. This method is part of the IConvertible interface and helps identify the specific type of a value at runtime. Syntax Following is the syntax for the SByte.GetTypeCode() method − public TypeCode GetTypeCode(); Return Value The method returns TypeCode.SByte, which is the enumeration constant representing the sbyte type. Using GetTypeCode() with SByte Values Example using System; public class Demo { public static void Main() { ...
Read MoreHow to create an OrderedDictionary in C#?
An OrderedDictionary in C# is a specialized collection that maintains the insertion order of key-value pairs. Unlike a regular Dictionary, it preserves the sequence in which elements were added, making it useful when order matters. The OrderedDictionary class is part of the System.Collections.Specialized namespace and provides both indexed access and key-based access to elements. Syntax Following is the syntax for creating an OrderedDictionary − OrderedDictionary dict = new OrderedDictionary(); dict.Add(key, value); dict[index] = value; // Access by index dict[key] = value; // Access by key Creating and Populating an ...
Read MoreQueue.IsSynchronized Property in C#
The Queue.IsSynchronized property in C# is used to determine whether access to the Queue is synchronized, meaning it is thread-safe for concurrent access by multiple threads. Syntax Following is the syntax for the IsSynchronized property − public virtual bool IsSynchronized { get; } Return Value The property returns a bool value − true − if access to the Queue is synchronized (thread-safe) false − if access to the Queue is not synchronized Using IsSynchronized with Regular Queue By default, a regular Queue is not synchronized and returns false ...
Read MoreHow to search in a row wise increased matrix using C#?
Searching in a row-wise sorted matrix is a common algorithmic problem where each row and column is sorted in ascending order. The naive approach of scanning all elements takes O(M×N) time complexity, but we can optimize this using a smart traversal strategy. The key insight is to start from either the top-right corner or bottom-left corner of the matrix. From the top-right position, if the target is smaller than the current element, move left; if larger, move down. This approach eliminates either a row or column in each step. Algorithm The search algorithm works as follows − ...
Read MoreQueue.Peek Method in C#
The Queue.Peek() method in C# is used to return the object at the beginning of the Queue without removing it. This method is useful when you need to examine the first element in the queue without modifying the queue's contents. Syntax Following is the syntax for the non-generic Queue − public virtual object Peek(); Following is the syntax for the generic Queue − public T Peek(); Return Value The method returns the object at the beginning of the Queue. For generic queues, it returns type T, and for non-generic ...
Read MoreTotal number of elements present in an array in C#
In C#, you can get the total number of elements present in an array using several different approaches. The most common methods are using the Length property, GetLength() method, or LongLength property for very large arrays. Syntax Following are the different ways to get array length − // Using Length property (most common) int count = arrayName.Length; // Using GetLength() method for specific dimension int count = arrayName.GetLength(0); // Using LongLength for very large arrays long count = arrayName.LongLength; Using Length Property The Length property is the most commonly used approach ...
Read MoreC# Program to Find the Sum of First N Natural Numbers
We are given a number N, and we need to calculate the sum of the first N natural numbers. Natural numbers are positive integers starting from 1 (i.e., 1, 2, 3, 4, 5, ...). In this article, we are going to learn how we can find the sum of the first N natural numbers in C#. Sum of First N Natural Numbers N = 5 1 2 3 4 ...
Read MoreHow to find all unique triplets that adds up to sum Zero using C#?
The three-sum problem involves finding all unique triplets in an array that sum to zero. This is a classic algorithmic challenge that can be solved efficiently using a two-pointer technique after sorting the array. Problem Statement Given an array of integers, find all unique triplets where nums[i] + nums[j] + nums[k] = 0. The solution must avoid duplicate triplets. Approach 1: Brute Force The simplest approach uses three nested loops to check every possible combination of three elements − Time Complexity − O(n³) Space Complexity − O(1) Approach 2: Optimized Two-Pointer Technique ...
Read MoreSingle.IsNaN() Method in C# with Examples
The Single.IsNaN() method in C# is used to determine whether a specified float value is not a number (NaN). This method returns true if the value is NaN, and false otherwise. NaN typically results from undefined mathematical operations like dividing zero by zero. Syntax Following is the syntax for the Single.IsNaN() method − public static bool IsNaN(float f); Parameters f − A single-precision floating-point number to be tested. Return Value Returns true if the value is NaN (Not a Number), otherwise false. ...
Read MoreStack.Synchronized() Method in C#
The Stack.Synchronized() method in C# returns a synchronized (thread-safe) wrapper for a Stack. This wrapper ensures that all operations on the stack are thread-safe, making it suitable for use in multi-threaded applications where multiple threads might access the same stack simultaneously. Syntax Following is the syntax for the Stack.Synchronized() method − public static System.Collections.Stack Synchronized(System.Collections.Stack stack); Parameters stack − The Stack object to synchronize. Return Value Returns a synchronized wrapper for the specified Stack. The returned wrapper provides thread-safe access to all Stack operations. Stack.Synchronized() Wrapper ...
