Conversion of Decimal to Dinary number

This is the code writen in c sharp .by which we can simply convert a decimal number in to binary

using System;

class Program{

   static void Main(string[] args){

     try{
        
  int i = (int)Convert.ToInt32(args[0]);
         Console.WriteLine("\n{0} converted to Binary is {1}\n",i,ToBin(i));
      
      }catch(Exception e){
        
         Console.WriteLine("\n{0}\n",e.Message);
 
      }

   }//here the insilize the system


  public static string ToBinary(Int32 Decimal)
  {
  //declare flag to need
   Int32 Binflag;
   char[] BinArray;
   string Bin = "";

   while (Decimal > 0)
   {
    Binflag = Decimal % 2;
    Bin += Binflag ;
    Decimal = Decimal / 2;
   }

   BinArray = Bin.ToCharArray();
   Array.Reverse(BinArray);
   Bin = new string(BinArray);

   return Bin;
  }
