Bypass elements in an array and return the remaining elements using the SkipWhile() method.The following is our array −int[] marks = { 45, 88, 55, 90, 95, 85 };Now, let’s skip the elements greater than or equal to 60. The condition we have set using Lambda Expression.IEnumerable selMarks = marks.AsQueryable().OrderByDescending(s ... Read More

Use ReadAllLines() method to read all the lines one by one in a file.Let’s say we have a file “new.txt” with the following lines.One Two ThreeFirstly, set the path of the file to be read.String myPath = "new.txt";Now add it under a string array to fetch the lines on by ... Read More

Reverse the elements in an array, using the Reverse method.Here is our character array.char[] ch = { 't', 'i', 'm', 'e' };Now use the Reverse() method with AsQueryable() method to get the reverse.ch.AsQueryable().Reverse();Let us see the complete code.Example Live Demousing System; using System.Linq; using System.Collections.Generic; public class Demo {    public ...

Here is our LinkedList.int [] num = {1, 3, 7, 15}; LinkedList list = new LinkedList(num);To check whether the list contains an element or not, use the Contains() method. The following example checks for node 3 in the list.list.Contains(3)Above, returns True since the element is found as shown below −Example Live ... Read More

The Year Month format specifier represents a custom date and time format string.It is defined by the DateTimeFormatInfo.YearMonthPattern property.Here is the custom format string.yyyy MMMMExample Live Demousing System; using System.Globalization; class Demo {    static void Main() {       DateTime date = new DateTime(2018, 9, 7, 7, 55, 20); ...

Declare a LinkedList and add nodes to it.string [] students = {"Tim", "Jack", "Henry", "David", "Tom"}; LinkedList list = new LinkedList(students);Let us add a new node.var newNode = list.AddLast("Kevin");Now, to add a node before the given node, use the AddBefore() method.list.AddBefore(newNode, "Matt");Let us now see the complete code.Example Live Demousing System; ... Read More

Firstly, set a string array.string [] students = {"Tim", "Jack", "Henry", "David", "Tom"};Now, add it to the LinkedList.LinkedList list = new LinkedList(students);The above creates a LinkedList and adds node to it.Let us see the complete example.Example Live Demousing System; using System.Collections.Generic; class Demo {    static void Main() {     ...
