Question

I write the code to scramble word I am create simple game jumble

         string jumble = theWord;
         int length = jumble.Count();
         for (int i = 0; i < length; ++i)
         {
             int index1 = (rand.Next() % length);
             int index2 = (rand.Next() % length);

             char  temp =jumble[index1];
             jumble = jumble.Replace(jumble[index1], jumble[index2]);
             jumble = jumble.Replace(jumble[index1], temp);

         }

update the code

         string jumble = theWord;
         int length = jumble.Count();
         for (int i = 0; i < length; ++i)
         {
             int index1 = (rand.Next() % length);
             //int index2 = (rand.Next() % length);

         char temp = jumble[index1];
         jumble[i] = jumble[index1 - 1];
         jumble[i] = temp;

         }

Answer 1

         StringBuilder jumbleSB = new StringBuilder();
         jumbleSB.Append(theWord);
         int lengthSB = jumbleSB.Length;
         for (int i = 0; i < lengthSB; ++i)
         {
             int index1 = (rand.Next() % lengthSB);
             int index2 = (rand.Next() % lengthSB);

             Char temp = jumbleSB[index1];
             jumbleSB[index1] = jumbleSB[index2];
             jumbleSB[index2] = temp;

         }

         Console.WriteLine(jumbleSB);
    }
