inheritance - How to override a method Inside another method using c# -

i'm new c# , need figure out how override class method inside new class method without implementing inheritance, in java can this:

class classa{   void method1(){        statements ....        ....        classb obj = new classbb(){             @override             void somemethod(){ //from classb               statements ....               ....             }        };      } } 

i want achieve same in c#.

you cannot in c#. if part of implementation call-site specific, use delegate, though. void method2() signature maps action (no parameters / return-value), so:

class classb {     private readonly action method2;     public classb(action method2) {         if(method2==null) throw new argumentnullexception("method2");         this.method2 = method2;     }     public void somemethod() {          ... uses method2()         method2();     } } 

then:

classb obj = new classb(() => {    // statements... }); 

with alternative identical syntax:

classb obj = new classb(delegate {    // statements... }); 

or:

classb obj = new classb(delegate() {    // statements... });
