CompositionUnder Composition, if the parent object is deleted, then the child object also loses its status. Composition is a special type of Aggregation and gives a part-of relationship.For example, A Car has an engine. If the car is destroyed, the engine is destroyed as well.public class Engine {    . . ... Read More

Set an array and arrange it in descending order using OrderByDescending.int[] prod = { 290, 340, 129, 540, 456, 898, 765, 789, 345};Now, use the Take() method to return specified number of elements from the beginning.Enumerable units = prod.AsQueryable().OrderByDescending(s => s).Take(2);Let us see the complete code.Example Live Demousing System; using System.Linq; ...

The Convert.ToByte method is used to convert a specified value to an 8-bit unsigned integer.Let’s say we have a char variable.Char charVal = ‘a’;Now, convert it to an 8-bit unsigned integer.byte byteVal = Convert.ToByte(charVal);Let us see another example now.Example Live Demousing System; public class Demo {    public static void Main() ...

The Sortable standard format specifier represents a custom date and time format string.The format string is defined by the DateTimeFormatInfo.SortableDateTimePattern property.The custom format string.yyyy'-'MM'-'dd'T'HH':'mm':'ssExample Live Demousing System; class Demo {    static void Main() {       DateTime date = new DateTime(2018, 9, 5, 2, 12, 40);       ...

The Count method returns the count of elements in a sequence.Let us first set an array.string[] arr = { "Java", "C++", "Python"};Now, use the Count() method to count the array elements.arr.AsQueryable().Count();The following is the complete example.Example Live Demousing System; using System.Linq; using System.Collections.Generic; class Demo {    static void Main() { ... Read More

The "#" custom format specifier works as a digit-placeholder symbol.If the value to be formatted has a digit in the position where the "#" symbol appears in the format string, then that digit is copied to the resultant string.We have set a double type here.double d; d = 4.2;Now, let ... Read More

The Any method checks whether any of the element in a sequence satisfy a specific condition or not.If any element satisfy the condition, true is returned.Let us see an example.int[] arr = {5, 7, 10, 12, 15, 18, 20};Now, using Any() method, we will check whether any of the element ... Read More

To reprsent Int64 as a Octal string in C#, use the ToString() method and set the base as the ToString() method’s second parameter i.e. 8 for Octal.Int64 represents a 64-bit signed integer.Firstly, set an Int64 variable.long val = 986766;Now, convert it to octal string by including 8 as the second ...
