C# looping through an array

Question

I am looping through an array of strings, such as (1/12/1992 apple truck 12/10/10 orange bicycle). The array\'s length will always be divisible by 3. I need to loop through

Answer 1

Just increment i by 3 in each step:

  Debug.Assert((theData.Length % 3) == 0);  // 'theData' will always be divisible by 3

  for (int i = 0; i < theData.Length; i += 3)
  {
       //grab 3 items at a time and do db insert, 
       // continue until all items are gone..
       string item1 = theData[i+0];
       string item2 = theData[i+1];
       string item3 = theData[i+2];
       // use the items
  }

To answer some comments, it is a given that theData.Length is a multiple of 3 so there is no need to check for theData.Length-2 as an upperbound. That would only mask errors in the preconditions.
