How to randomise text in c#?

I want to make a c# program which generates random numbers, but I can't find how to.
The code I've come up with so far:

using System;

namespace DigitalDice
  {
      class Program
      {
        static void Main(string[] args)
       {
          Console.WriteLine("[1]");
      }
   }
}

I just need a way to make random words, the example I'm looking for is how to randomise with 2 different outputs, then I can change it to how I like it.

> I am not sure what you want exactly but if you are looking for

public class Program {
    public static void Main(string[] args) {
        var res = Randomise("12345");
        Console.WriteLine(res);
        Console.ReadKey();
    }

    public static string Randomise(string input)
    {
        string res = string.Empty;
        Random random = new Random();
        while (!string.IsNullOrEmpty(input)) {
            int num = random.Next(input.Length);
            res += input.Substring(num, 1);
            input = input.Remove(num, 1);
        } 
        return res;
    }
}

You can generate Randomize words using below code.

Below code also helps you to define length of the random word.

First, Have a method to return a random word

/// <summary>
/// Pass legth of random word you need to generate
/// </summary>
/// <param name="wordLength"></param>
/// <returns></returns>
static string RandomLetter(int wordLength)

{
    string randLetter = " ";
    string randWord = " ";

    string[] letters = new string[26]  { " a", " b", " c", " d", " e", " f", " g", " h", " i", " j", " k", " l", " m", " n",

           " o", " p", " q", " r", " s", " t", " u", " v", " w", " x" , " y", " z"};

    Random rnd = new Random();

    for (int s = 0; s < wordLength; s++)

    {
        //make newrandom to 26
        int newRandomNumber = rnd.Next(1, 26);
        //it finds the letter thas is associated to the number
        randLetter = letters[newRandomNumber];
        randWord += randLetter;
    }
    //it returns word without spaces
    return Regex.Replace(randWord, @"\s+", "");
}

Next, Call the above method to get a random word

///Main method
public static void Main(string[] args)
{
    Console.WriteLine(RandomLetter(5));
}

Ref: Code snippet

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using System.Text.RegularExpressions;

class Program

{
    /// <summary>
    /// Pass legth of random word you need to generate
    /// </summary>
    /// <param name="wordLength"></param>
    /// <returns></returns>
    static string RandomLetter(int wordLength)

    {
        string randLetter = " ";
        string randWord = " ";

        string[] letters = new string[26]  { " a", " b", " c", " d", " e", " f", " g", " h", " i", " j", " k", " l", " m", " n",

               " o", " p", " q", " r", " s", " t", " u", " v", " w", " x" , " y", " z"};

        Random rnd = new Random();

        for (int s = 0; s < wordLength; s++)

        {
            //make newrandom to 26
            int newRandomNumber = rnd.Next(1, 26);
            //it finds the letter thas is associated to the number
            randLetter = letters[newRandomNumber];
            randWord += randLetter;
        }
        //it returns word without spaces
        return Regex.Replace(randWord, @"\s+", "");
    }
    
    ///Main method
    public static void Main(string[] args)
    {
        Console.WriteLine(RandomLetter(5));
    }

}
