Orders elements in a sequence using ThenBy() method.We have the following string array.string[] str = { "AAA", "AAAA", "A", "AAAAA", "AAAAAAAAA" };Now, use Lambda Expressions and set a condition inside the ThenBy() method to sort the strings according to the number of characters they have.IEnumerable res = str.AsQueryable() .OrderBy(alp => ...

To get the bounds of a three-dimensional array, use the GetUpperBound() GetLowerBound() methods in C#.The parameter to be set under these methods is the dimensions i.e.Let’s say our array is −int[, , ] arr = new int[3, 4, 5];For a three-dimensional arrays, dimension 0.arr.GetUpperBound(0) arr.GetLowerBound(0)For a three-dimensional arrays, dimension 1.arr.GetUpperBound(1) ...

Set two sequences.double[] arr1 = { 10.2, 15.6, 23.3, 30.5, 50.2 }; double[] arr2 = { 15.6, 30.5, 50.2 };To get the difference between both the above arrays, use Except() method.IEnumerable res = arr1.AsQueryable().Except(arr2);The following is the complete code.Example Live Demousing System; using System.Linq; using System.Collections.Generic; class Demo {    static ...

The Single() method returns the only element that satisfies a condition. If more than one such element is visible, then an error is thrown.The following is our string array.string[] str = { "jack", "tom", "henry", "time"};Now, use the Single() method to get each element. Then, we have used Lambda Expression ... Read More

The WindowsTop property is used to gets or set the top position of the console window area relative to the screen buffer.Declare an integer variable to get the top position.int top;Now, use the Console.WindowTop property.top = Console.WindowTop;Let us see the complete example.Example Live Demousing System; class Demo {    static void ...

Use the FirstorDefault() method to return the first element of a sequence or a default value if element isn’t there.The following is our empty list −List val = new List { };Now, we cannot display the first element, since it is an empty collection. For that, use the FirstorDefault() method ... Read More

Get the minimum value from a sequence using the Min() method in C#.The following is our list.List list = new List { 1, 2, 3, 4, 5, 6 };Now, use Queryable Min() method to get minimum element.list.AsQueryable().Min();Exampleusing System; using System.Collections.Generic; using System.Linq; class Demo {    static void Main() { ... Read More

The following is our Hashtable −Hashtable h = new Hashtable(); h.Add(1, "Jack"); h.Add(2, "Henry"); h.Add(3, "Ben"); h.Add(4, "Chris");To remove an item, use the Remove() method. Here, we are removing the 3rd element.h.Remove(3);Let us see the complete example.Example Live Demousing System; using System.Collections; public class Demo {    public static void Main() ...

The Parse method in Enum converts the string representation of the name or numeric value of enum constants to an equivalent enumerated object.The following is our enumeration.enum Vehicle { Car, Bus, Truck, Motobike };Now, use the GetNames() method in a loop to get the enum values. Parse them using the ... Read More

Firstly, declare a LinkedList and add nodes.int [] num = {92, 98, 110, 130, 145, 170, 230, 240, 250, 300, 330}; LinkedList myList = new LinkedList(num);Remove the last node from the LinkedList using the RemoveLast() method.myList.RemoveLast();Example Live Demousing System; using System.Collections.Generic; class Demo {    static void Main() {     ...
