C# Iterate over string question

Hello all,

I have a string where I need to take only up to 30 characters then after that create a new line. It needs to also not split in between a word. How can I do this until the end of the string?

How about this:

static class Extensions
{
	public static string WrapText(this string source, int length)
	{
		var count = 0;
		var lines = source.Split(new string[] { " " }, StringSplitOptions.RemoveEmptyEntries)
			.GroupBy(word => (count += word.Length + 1) / length)
			.Select(group => string.Join(" ", group.ToArray()));

		return string.Join("\n", lines.ToArray());
	}
}

Open in new window

Example usage -

using System;
using System.Linq;

namespace EE_Q28700647
{
	class Program
	{
		static void Main(string[] args)
		{
			var longstring = "Lorem ipsum dolor sit amet, odio etiam natoque aliquet nostra, mauris suspendisse, ad duis, faucibus accumsan. Tortor massa suspendisse pharetra quis imperdiet. Consectetuer eu massa metus pharetra massa pulvinar, nec maecenas lorem ultrices, tortor nec ornare platea nam, nunc tortor. Odio sed consequatur et vehicula pellentesque, vel ipsum, sit in ipsum dignissim neque, tempor ipsum diam, nascetur rhoncus duis venenatis a. Libero mauris. Id etiam suspendisse. Id congue in enim adipiscing sit morbi, sit a, id in. Habitasse nulla, nunc sollicitudin commodo id eleifend tristique, justo quis fames, vehicula hic mi. Sapien ut aptent consectetuer.";
			Console.WriteLine(longstring.WrapText(30));
			Console.ReadLine();
		}
	}

	static class Extensions
	{
		public static string WrapText(this string source, int length)
		{
			var count = 0;
			var lines = source.Split(new string[] { " " }, StringSplitOptions.RemoveEmptyEntries)
				.GroupBy(word => (count += word.Length + 1) / length)
				.Select(group => string.Join(" ", group.ToArray()));

			return string.Join("\n", lines.ToArray());
		}
	}
}

Open in new window
