An abstract class in C# includes abstract and non-abstract methods. A class is declared abstract to be an abstract class.

This is why Deque is said to be a double-ended queue.The Deque class has the following methods in the Queue class −ClearClears the collection of all of its elementsContainsWhether or not an object is in the collectionToArrayUse the ToArray() method to copy all of the elements ...

To refer to the fields of the current class, we have used the “this” keyword in C# −public Student(int id, String name, int age, String subject) {    this.id = id;   ... Read More
