c# bubble sort string array
You can use string.Compare(x,y) instead of &lt;, 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)
