Split a String to a String[] so that each element is maximum 100 characters and ends in a space

Question

How do i do this? I tried something like this but I do not seem to be able to get any further.

public void speak(String text)
{
    String[] textArray = text.spl         


        

Answer 1

I know this answer is late and a bit inefficient but I think it does the job nicely.

public class StringSplitter
{ 
  private int maxCharactersPerLine = 100;

  public List GetTextLines(string text)
  { 
    var result = new List();

    if(text.Length <= this.maxCharactersPerLine)
    {
      result.Add(text);
      return result;
    }

    string words[] = text.Split(new[]{' '}, StringSplittingOptions.RemoveEmptyEntries);

    //accumolator, describes a line of text up to maximum character length.
    string temp = string.Empty; 

    //this is so that we don't append an empty space on each new line.
    bool isBeginingWord = true;

    foreach(var word in words)
    {
      //there is a possibility that a text line has more than maximum
      //consecutive characters without having a space. This is edge case. 
      if(temp.Length > this.maxCharactersPerLine)
      {
        result.Add(temp);
        continue;
      }

      //if adding the next word in the list will exceed the 
      //maximum characters per line of text
      if((temp + " " + word).Length > this.maxCharactersPerLine)
      {
        result.Add(temp);      //add the accumolator to the list.
        temp = "";             //reset the accumolator
        isBeginingWord= true;  //reset beginning of word flag.
        continue;
      }

      //adding the next word from the list results in accumolator still
      //still shorter than the maximum characters per line of text.
      if(isBeginingWord)
      {
        temp = word;
        isBeginingWord = false;
        continue;
      }

      temp = temp + " " + word;
    }

    return result;
  }
}
