    char[] x=inputString.ToCharArray();
    StringBuilder sb = new StringBuilder();
    for(int i=inputString.Length-1;i>=0;--i)
    {
      sb.Append(x[i]);

    Console.Write(sb.ToString());
    Console.ReadKey();
  }
}

string result = "";
string inputString = "This is paragraph.";
for (int i = inputString.Length - 1; i >= 0; i--)
{
    result += inputString[i];
}
Console.WriteLine(result);
Console.ReadLine();
