c# - Error: 'Flow': member names cannot be the same as their enclosing type -

using system;  using system.collections.generic;  using system.linq;  using system.text;  using system.threading.tasks;   namespace cofbalu {  class strongno {  static int factorial(int rem) {      if (rem == 1) return 1;      else return factorial(rem - 1) * rem; }   static int strongno(int n) {       int rem=0,strong=0;       while (n > 0) {       strong = strong + factorial(rem = n % 10);      n = n / 10;       }  return strong;  }   static void main() {     console.write("enter no: ");     int n = int.parse(console.readline());     if (strongno(n) == n) console.write("yes, "+n+" strong no.");       else console.write("no, " + n + " not strong no.");     console.readline();  }  }  } 

your method static int strongno(int n) having same name class name. , method name have name of class called constructor. , constructors not have return type.

so can try rename function this:

static int strongnumber(int n)
