string str = "%Pro#gramm&ing"; string strOriginal = string.Empty; char[] reversed = str.ToCharArray().Reverse().ToArray(); foreach (char chr in reversed) { strOriginal = strOriginal + chr.ToString(); } Console.WriteLine(str); Console.WriteLine(strOriginal); Simplyfied Code : string str = "%Pro#gramm&ing"; char[] reversed = str.ToCharArray().Reverse().ToArray(); Console.WriteLine(str); Console.WriteLine(reversed);

Hello, Try to this code it's just a logic in c# but also you can use same logic in your comfotable technology string str = "" , reverse = "" ; int Length = 0; Console.WriteLine( "Enter a String" ); str = Console.ReadLine(); Length = str.Length - 1; while (Length>=0) { reverse = reverse + str[Length]; Length--; } Console.WriteLine( "Reverse word is {0}" ,reverse); Console.ReadLine();

private static void Main(string[] args) { try { string str = "%Pro#gramm&ing"; var reverseStr = Reverse(str.ToCharArray()); Console.WriteLine(reverseStr); Console.ReadLine(); } catch (Exception ex) { // ignored } } static string Reverse(char[] str) { // Initialize left and right pointers int strlen = str.Length - 1; int l = 0; // Traverse string from both ends until while (l { // Ignore special characters if (!IsAlphabet(str[l])) l++; else if (!IsAlphabet(str[strlen])) strlen--; else { SwapChars(ref str[l], ref str[strlen]); l++; strlen--; } } return new string(str); } private static void SwapChars(ref char a, ref char b) { char c = a; a = b; b = c; } static bool IsAlphabet(char x) { return ((x >= 'A' && x (x >= 'a' && x } }

Try this var reversedWords = string.Join(" ", str.Split(' ') .Select(x => new String(x.Reverse().ToArray())));
