By using the HTML Agility Pack:

To extract all the text nodes in the HTML.

This question explains how you would do that:

C#: HtmlAgilityPack extract inner text

public static string Strip(string source)
{
    char[] array = new char[source.Length];
    int arrayIndex = 0;
    bool inside = false;

    for (int i = 0; i < source.Length; i++)
    {
        char let = source[i];
        if (let == '<')
        {
            inside = true;
            continue;
        }
        if (let == '>')
        {
            inside = false;
            continue;
        }
        if (!inside)
        {
            array[arrayIndex] = let;
            arrayIndex++;
        }
    }
    string text =  new string(array, 0, arrayIndex);
    return System.Text.RegularExpressions.Regex.Replace(text, @"\s+", " ").Trim();
}

Can you so something like:

(Get the record first then add a property to return some of the text)

return Text.Length >= 100 ? Text.SubString(0,100) : Text;
