Limit string list add

Hi stack overflow users, I have created a fully functional Hangman Game in C# now I am polishing the last parts before handing the assignment in.
I decided to create three different difficulties "Easy" "Medium" "Hard" instead of letting the user pick the amount of life.
Now to the question?
Is there a function to add words into the word list (which then get randomly selected by a method)? I would like to limit the min and max length of the words that the user adds onto the list of words.
Below is the class for my WordList.

using System;
using System.Collections.Generic;

class WordList
{
    public static list <string>word = new list<string>();

    public void Showwordlist()
    {
        word.sort();
        foreach (string word in words)
        {
            console.WriteLine("- " + word);
        }
    }

    public void Addwords(string input)
    {
        word.add(input);
    }
}

Add a check to see if it meets the minimum length and is less than the maximum length:

private int minimumLength = 4;
private int maximumLength = 20;

public void Addwords(string input)
{
    if(input.Length >= minimumLength && input.Length <= maximumLength)
        word.add(input);
    else
        MessageBox.Show("Word length must be between " + minimumLength + 
                         @" and " maximumLength + " characters");
}

I'm assuming that the bounds are all inclusive so I'm using the >= and <= operators. The MessageBox.Show is assuming that you're using Windows Forms. Otherwise, handle the error message appropriately.

You can also use RegularExpressions to limit the characters used in the words as well as the length. In the regular expression below, only words that contain upper and lower case letters that are between 2 and 10 characters would be allowed.

public void Addwords(string input)
{
    Match match = Regex.Match(input, "^[a-zA-Z.]{2,10}$");
    if (match.Success)
    {
        word.add(input);
    }
}

Like this?

public void Addwords(string input)
{
    if(input.Length < minLength)
        throw new Exception("Too Short");  // example only - throw a better exception
    if(input.Length > maxLength)
        throw new Exception("Too Long");   // example only - throw a better exception

    word.add(input);
}
