Hi All,
 Can any one Tell me how to Reverse a String with out using string function() in C#?
For example i have string like
string s="He is palying in a ground.";

HI,

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

I think the above works not tested, although the stringbuilder class may also have a reverse function I haven't checked that though.

REVERSE OF A STRING WITHOUT USING FUNCTION:

class ReverseString
   {
     public static void Main(string[] args)
     {
       string Name = "He is palying in a ground.";
       char[] characters = Name.ToCharArray();
       StringBuilder sb = new StringBuilder();
       for (int i = Name.Length - 1; i >= 0; --i)
       {
         sb.Append(characters[i]);
       }
       Console.Write(sb.ToString());
       Console.Read();
     }
   }

Hope this will help you :-)

Use this function

convert to character array and display from reverse by iterating reversely
public string Reverse(string text)
{
    char[] cArray = text.ToCharArray();
    string reverse = String.Empty;
    for (int i = cArray.Length - 1; i > -1; i--)
    {
        reverse += cArray[i];
    }
    return reverse;
}

hi,

Just pass your string in below function to get reverse order
public string Reverse(string str)
{
  int len = str.Length;
  char[] arr = new char[len];
 
  for (int i = 0; i < len; i++)
  {
  arr[i] = str[len - 1 - i];
  }
 
  return new string(arr);
}

hope this will help you

Use this function
 


private string Reverse(string stringToReverse)
    {
        char[] rev = stringToReverse.Reverse().ToArray();
        return new string(rev); 
    }
