Checking if two strings are permutations of each other

Question

How to determine if two strings are permutations of each other

Answer 1

I did it using C#

bool Arepermutations(string string1, string string2)
        {
            char[] str1 = string1.ToCharArray();
            char[] str2 = string2.ToCharArray();
            if (str1.Length !=str2.Length)
              return false; 
            Array.Sort(str1); 
            Array.Sort(str2);
            if (str1.Where((t, i) => t!= str2[i]).Any())
            {
                return false;
            }

            return true; 

        }
