string array bubble sort c# code example

Example: c# bubble sort string array

You can use string.Compare(x,y) instead of <, which returns 0 if the string are equal, otherwise an integer that indicates their relative position in the sort order

    for (int index = 0; index < (letters.Length - 1); index++)
    {
        if (string.Compare (letters[index], letters[index + 1]) < 0) //if first number is greater then second then swap
        {
            //swap

            temp = letters[index];
            letters[index] = letters[index + 1];
            letters[index + 1] = temp;
            swap = true;
        }
    }
If you want to ignore case during the comparison, you should use string.Compare (letters[index], letters[index + 1], true)
