Make Console.WriteLine() wrap words instead of letters

Question

Using Console.WriteLine(), this it output:

I want it to look like this automatically, instead of manually putting in \n wherever needed:

Is this possible? If so, how?

Answer 1

Here is a solution that will work with tabs, newlines, and other whitespace.

using System;
using System.Collections.Generic;

/// <summary>
///     Writes the specified data, followed by the current line terminator, to the standard output stream, while wrapping lines that would otherwise break words.
/// </summary>
/// <param name="paragraph">The value to write.</param>
/// <param name="tabSize">The value that indicates the column width of tab characters.</param>
public static void WriteLineWordWrap(string paragraph, int tabSize = 8)
{
    string[] lines = paragraph
        .Replace("\t", new String(' ', tabSize))
        .Split(new string[] { Environment.NewLine }, StringSplitOptions.None);

    for (int i = 0; i < lines.Length; i++) {
        string process = lines[i];
        List<String> wrapped = new List<string>();

        while (process.Length > Console.WindowWidth) {
            int wrapAt = process.LastIndexOf(' ', Math.Min(Console.WindowWidth - 1, process.Length));
            if (wrapAt <= 0) break;

            wrapped.Add(process.Substring(0, wrapAt));
            process = process.Remove(0, wrapAt + 1);
        }

        foreach (string wrap in wrapped) {
            Console.WriteLine(wrap);
        }

        Console.WriteLine(process);
    }
}

This will take a string and return a list of strings each no longer than 80 characters):

var words = text.Split(' ');
var lines = words.Skip(1).Aggregate(words.Take(1).ToList(), (l, w) =>
{
    if (l.Last().Length + w.Length >= 80)
        l.Add(w);
    else
        l[l.Count - 1] += " " + w;
    return l;
});

Starting with this text:

var text = "Hundreds of South Australians will come out to cosplay when Oz Comic Con hits town this weekend with guest stars including the actor who played Freddy Krueger (A Nightmare on Elm Street) and others from shows such as Game of Thrones and Buffy the Vampire Slayer.";

I get this result:

Hundreds of South Australians will come out to cosplay when Oz Comic Con hits 
town this weekend with guest stars including the actor who played Freddy Krueger 
(A Nightmare on Elm Street) and others from shows such as Game of Thrones and 
Buffy the Vampire Slayer.

Coded in a couple of minutes, it will actually break with words that have more than 80 characters and doesn't take into consideration the Console.WindowWidth

private static void EpicWriteLine(String text)
{
  String[] words = text.Split(' ');
  StringBuilder buffer = new StringBuilder();

  foreach (String word in words)
  {
    buffer.Append(word);

    if (buffer.Length >= 80)
    {
      String line = buffer.ToString().Substring(0, buffer.Length - word.Length);
      Console.WriteLine(line);
      buffer.Clear();
      buffer.Append(word);
    }

    buffer.Append(" ");

  }

  Console.WriteLine(buffer.ToString());
}

It's also not very optimized on both CPU and Memory. I wouldn't use this in any serious context.
