Objects in c#

• Object can store any kind of value because object is a base class of all the classes in .net framework.


• Employee obj=new Employee();


• Object is not type safe


• Object can be initialize with null


• Object type can be passed as method parameter also it can return object type.

       For example:

public object Method2(object param)
            {
            object objResponse = param;
            return objResponse;
            }

• Casting is required in Object

Dynamic in c#

• Dynamic type can store any kind of value.


• dynamic obj;


• Dynamic is not type safe


• Dynamic can be initialize with null


• Dynamic type can be passed as method parameter also it can return dynamic type.

See example below:

  public dynamic Method(dynamic param)
            {
            dynamic objResponse = param;
            return objResponse;
            }

• Casting is not require but you need to know the property and methods related to stored type
