C # Reflection and Reflection interface

The reflection is described in the previous article, the following is mainly about the actual use of some reflection.

By reflecting us, I can get the interface and also get the class that implements the interface, at which point the interface reference can access an instance of the implementation class.

I first defined an interface:

     Public Interface IPerson    {         void SetName (string  name);          void SayHello ();         }

To define a class implementation:

namespacepeople{ Public classPeople:iperson { Public stringName {Set; Get; }         Public stringSex {Set; Get; }         Public stringAge {Set; Get; }         Publicpeople () {} PublicPeople (stringname) {Name=name; }         Public voidSetName (stringname) {Name=name; }         Public voidSayHello () {Console.WriteLine ("Hello everyone, I am:"+Name); }    }}

Implemented by reflection:

namespaceconsoleapp1{classProgram {Static voidMain (string[] args) {IPerson IPerson=NULL; Assembly Assembly= Assembly.Load ("people"); Type[] Types=Assembly.            GetTypes (); foreach(varTinchtypes) {                if(T.getinterface ("IPerson") !=NULL) {IPerson=(IPerson) activator.createinstance (t); }            }            if(IPerson! =NULL) {IPerson. SetName ("Vidyut 厶"); IPerson.            SayHello ();        } console.readline (); }    }}
