program for armstrong series

Question

Write a program for armstrong series? I have tried in c++ but i want in C#.

#include "iostream"
#include "math.h"

using namespace std;

int main()
{
  /*armstrong number -> if sum of cubes of indiviual digits is equal to the number itself
  eq- if number is 371 => 3*3*3 + 7*7*7 + 1*1*1 = 371 (armstrong number)
  */
  int num,cube=0,temp=0;
  double remainder=0;
  cout<<"enter the number";
  cin>>num;

  temp=num;

  while(temp !=0)
  {
    remainder = temp % 10;
    cout<<"remainder"<<remainder<<endl;
    cube+=pow(remainder,3);
    cout<<"cube"<<cube<<endl;
    temp=temp/10;
    cout<<"temp"<<temp<<endl;

  }

  if(cube==num)
  {
    cout<<"Number is armstrong";
  }
  else
    cout<<"not";

  return 0;
}
