To convert an Int32 value to a decimal, use the Convert.ToDecimal() method.Int32 represents a 32-bit signed integer.Let’s say the following is our Int32 value.int val = 2923;Now to convert it to decimal.decimal decVal = Convert.ToDecimal(val);Let us see the complete example.Example Live Demousing System; public class Demo {    public static void ...

To convert a Double value to an integer value, use the Convert.ToInt32() method.Int32 represents a 32-bit signed integer.Let’s say the following is our double value.double val = 21.34;Now to convert it to Int32.int res = Convert.ToInt32(val);Let us see the complete example.Example Live Demousing System; public class Demo {    public static ...

To cast elements, use the Cast() method.The following is our list.List myList = new List { "Mac", "Windows", "Linux", "Solaris" };Now, cast and use the Cast() method with substring() method to display the first two letters of every string in the list.IEnumerable res = myList.AsQueryable().Cast().Select(str => str.Substring(0, 2));Let us see ...

To orders elements in a sequence in descending order, use ThenBy() and OrderByDescending.This is our string array.string[] myStr = { "Keyboard", "Laptop", "Mouse", "Monitor" };Now, use OrderByDescending to order element in Descending order. Inside that calculate the length of each string and use Lambda Expressions as well.IEnumerable res = myStr.AsQueryable().OrderByDescending(ch ... Read More

Merge sequences using predicate with Zip method.Here are our arrays to be merged.int[] intArray = { 10, 20, 30, 40 }; string[] stringArray = { "Jack", "Tim", "Henry", "Tom" };Now let’s use the Zip method to merge both the arrays.intArray.AsQueryable().Zip(stringArray, (one, two) => one + " " + two)The following ... Read More

Skip elements from the end and return the remaining elements using the SkipLast() method.The following is an array.int[] marks = { 45, 88, 50, 90, 95, 85 };Now, let us skip two elements from the end using SkipLast() and Lambda Expressions, but this is done after arranging the elements in ... Read More

Find the sum of elements using the Linq Sum() method.Here’s our list with integer elements.List list = new List { 99, 34, 77, 75, 87, 35, 88};Now find the sum using the Sum() method.list.AsQueryable().Sum();The following is an example to find the sum of elements of a list with integer elements.Example Live ...

Get elements as long as the condition is true in a sequence using the TakeWhile() method.The following is our list with strings.IList str = new List(){ "Car", "Bus", "Truck", "Airplane"};Now, let’s say we need the strings whose length is less than 4. For that, use Lambda Expressions and add it ... Read More

Declare a string array.string [] students = {"Jenifer", "Angelina", "Vera"};Add it to a LinkedList.string [] students = {"Jenifer", "Angelina", "Vera"};Now, use AddLast() method to add a node at the end.list.AddLast("Anne");Example Live Demousing System; using System.Collections.Generic; class Demo {    static void Main() {       string [] students = {"Jenifer", ... Read More

The method returns a single specific element of a sequence. If the element is not present in the sequence, then the default value is returned.We have two string arrays here.string[] str1 = { "one" }; string[] str2 = { };First array is checked for a single element, whereas the second ... Read More
