Difference between 'is'and 'as' operator in C#

Question

Anupam Mishra · Answer

“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();
if(stud== 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;
