We need to write a simple C# code to demonstrate a reversing the given input string at runtime. Below is the code snippet to achive this.

 class Program
 {
 internal static void ReverseString(string str)
 {
 char[] charArray = str.ToCharArray();
 for (int i = 0, j = str.Length - 1; i < j; i++, j--)
 {
                charArray[i] = str[j];
                charArray[j] = str[i];
 }
 string reversedstring = new string(charArray);
 Console.WriteLine(reversedstring);
 }
 static void Main(string[] args)
 {
 ReverseString(args[0]);
 Console.ReadKey();
 }
 }

In more simple way we can revese string like this.

 static void ReverseString(string str)
 {
 string nStr = string.Empty;
 foreach (var item in str)
 {
                nStr = item + nStr;
 }
 Console.WriteLine(nStr);
 }

Public static void Program() {string input =Console.ReadLine();string Reverse(string str) {string result = string.Empty;var x = str.ToCharArray();for(int i = x.Length - 1; i >=0 ;i--){result = x[i] ;} return result;} Console.WriteLine(Reverse(input)); }

public static string Reverse( string s ) {char[] charArray = s.ToCharArray();Array.Reverse( charArray );return new string( charArray ); }

 public static string ReverseString(string input)
 {
 string output = "";
 for (int i = input.Length-1; i >= 0; i--)
 {
            output+=input[i];
 }
 return output;
 }
