Limiting words in a text box

I'm trying to create a text box in c# that will only contain 100 words and after the 100th word no other text can be input into the box.

A simple approach which might be inaccurate because it replaces consecutive white-spaces with one:

private void textBox1_TextChanged(object sender, EventArgs e)
{
    string[] words = textBox1.Text.Split();
    int wordCount = words.Length;
    if (wordCount > 100)
        textBox1.Text = string.Join(" ", words.Take(100));
}

instead of the String.Join you could replace it with the old text:

private string oldText;
private void textBox1_TextChanged(object sender, EventArgs e)
{
    string[] words = textBox1.Text.Split();
    int wordCount = words.Length;
    if (wordCount > 100)
        textBox1.Text = oldText;
    else
        oldText = textBox1.Text;
}

On the TextChanged event of the textbox, count the ocurrences of white spaces and line breaks. If they're greater than 99, don't allow the text to change. You'll have to keep a copy of its text in another variable so that you can revert to that if the user inputs thr 101th word.
