extract content from html code at code behind

Question

Hi All, I have a field coming from database, it is a html code. sample: "html tag"extract content from html code at code behind"/html tag""html tag"did have solution?"/html tag" At code behind I need to count the text, such like "extract content from html code at code behind" + "did have solution?". if the length exceeds the limit, do something. How can I get the real text without HTML tag in my cs file? Thank you in advance.
