What is the difference between the below 2 statements and when to use what? 1) IList stdList = new List (); 2) List stdList = new List ();

It would be great if you let us know the advantages and disadvantages of using IList EmpList = new List (); over the other one.

IList is an interface. List is a concrete class. Either of these will be valid: IList EmpList = new List (); and List EmpList = new List (); However, you cannot instantiate an interface, i.e. the following will fail: IList EmpList = new IList (); https://stackoverflow.com/questions/12369570/difference-between-ilistt-and-listt
