c# text randomizer {variant1|varian2|...variantN}

For example I have text like this - "i want to buy a {car|home|etc}". Is there any lib to randomize text? I.e. make 3 strings

You could predefine the strings in an array that then generate a random integer using the Random class.

var string[] data = new string[] {"car", "home", "etc"};
var rand = new Random();
var text = "I want to buy a " + data[rand.Next(data.Length)];

I think this is a job for Regex.Replace:

private void button1_Click(object sender, EventArgs e)
{
    string text = Regex.Replace(textBox1.Text, "{(.*?)}", PickRandomWord);
    ...
}

private Random random = new Random();
private string PickRandomWord(Match match)
{
    string[] words = match.Groups[1].Value.Split('|');
    return words[random.Next(words.Length)];
}

This will pick one random text.

First I think you have to create your own words dictionary

After use some randomizer, for example this one: Random Sentences and Paragraphs

EDIT

There are could be plenty of other type of solutions, so please clarify your problem to get more correct answer.

Regards.

public String CalculateRandomString(String input)
{
   String s = input.Substring(0, input.IndexOf('{'));
   String choiceString = input.Substring(input.IndexOf('{'), input.IndexOf('}'));
   String[] choices = choiceString.Split('|');
   Random rand = new Random();
   int choice = rand.Next(0, choices.Length);

   return s + choices[choice];
}

Notes:

• Only works if the choices are at the end of the string.

//demonstration
index = string.indexOf('{');

if(index != -1)
{
   string.remove(0, index);

   endIndex = string.indexOf('}', index);

   if(endIndex != -1)
   {
      list = string.remove(endIndex, string.length - endIndex).split('|').toList();
      return list[rand.next(list.count)];
   }
}

If you want it to parse every instance, then set it in a while loop that checks if the index is -1 and use string.insert();

This is the function I made for spinable text

        private string spinString(string s)
        {
            string  ret,
                    temp;

            string[] spinables;

            int index,
                i;

            Random a;


            a = new Random();
            ret = null;
            i = 0;

            while (true)
            {
                if (i == s.Length)
                    break;

                if (s[i] == '{')
                {
                    temp = s.Remove(0, i + 1);

                    index = temp.IndexOf('}');

                    if (index != -1)
                    {
                        temp = temp.Remove(index, temp.Length - index);

                        spinables = temp.Split('|');

                        temp = spinables[a.Next(spinables.Count())];

                        index = s.IndexOf('}', i);

                        if (index != -1)
                        {
                            s = s.Remove(i, index - i + 1);

                            s = s.Insert(i, temp);
                        }


                    }

                }

                try
                {
                    ret += s[i];
                }
                catch (Exception e)
                {
                    e.ToString();
                    break;
                }

                i++;
                Thread.Sleep(10);
            }


            return ret;
        }

Try this -

String[] strings = {"car", "home", "boat"};
var output = "I want to buy a " + strings.OrderBy(en => System.Guid.NewGuid()).First();
