Hello Raja A , Kindly use below code , this may helped you- Design page- @ Page Language ="C#" AutoEventWireup ="true" CodeFile ="NumberCheck.aspx.cs" Inherits ="NumberCheck" %> DOCTYPE html > html xmlns ="http://www.w3.org/1999/xhtml"> head runat ="server"> title > title > head > body > form id ="form1" runat ="server"> div > div > form > body > html > Codebehind page- using System; using System.Collections.Generic; using System.Linq; using System.Text.RegularExpressions; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; public partial class NumberCheck : System.Web.UI. Page { protected void Page_Load( object sender, EventArgs e) { Printnumber(); } protected void Printnumber() { for ( int i = 30; i { if (i.ToString().Length > 1) { if (! test .IsConsecutiveThroughLinq(i.ToString())) { Response.Write(i + " " ); } else { Response.Write( " " ); } } } } } static class test { public static bool IsConsecutiveThroughLoops( this string value) { var digits = value.ToString().ToList(); var differences = new List Int32 >(); for ( int i = 0; i { if (i != digits.Count - 1) // not the last number { var difference = digits[i] - digits[i + 1]; // subtract the current digit from the next digit differences.Add(difference); } } // consecutive numbers will always have the same difference and that difference must be -1 or 1 (immediate) if (differences.Distinct().Count() == 1 && (differences.First() == 1 || differences.First() == -1)) { return true ; } return false ; } } if this helped you kindly accept the answer for better discussion . I will also provide this solution using different concept.

Hi Raja, try the below code static void Main(string[] args) { for (int i = 30; i { bool asc = false; bool desc = false; string str = i.ToString(); for (int j = 0; j { if (Convert.ToInt32(str[j]) + 1 == Convert.ToInt32(str[j+1])) { asc = true; } else { asc = false; break; } } for (int j = 0; j { if (Convert.ToInt32(str[j]) - 1 == Convert.ToInt32(str[j + 1])) { desc = true; } else { desc = false; break; } } if (asc==false && desc==false) { Console.WriteLine(i); } } Console.ReadLine(); } If you find anything helpful please accept my answer.
