“IS” operator is useful to check if objects are compatible with a type. For instance in the below code we are checking if “stud” object is a type of “Student” class.
object stud = new Student();
“AS” operator helps to do conversion from one
type to other type. For instance in the below code we are converting object to
a string data type. If the “AS” operator is not able to type cast it returns NULL
object obj = "Anupam";
string str = obj as string;
