Write the difference between TypeOf and GetType?

TypeOf:- is an operator to obtain a type known at compile-time (or at least a generic type parameter). The operand of typeof is always the name of a type or type parameter - never an expression with a value (e.g. a variable). Used to obtain the System.Type object for a type. A typeof expression takes the following form: System.Type type = typeof(int); GetType():-GetType() is a method you call on individual objects, to get the execution-time type of the object. Gets the Type of the current instance. The exact runtime type of the current instance. int i = 0; System.Type type = i.GetType();

typeof is used to get the type based on a class. That means if you use typeof with object, it will gives you error. You must pass class as parameter parameter. Where GetType is used to get the type based on an object (an instance of a class). Means GetType needs parameter of object rather than class name.
