Solution 1

Remove the text file from your VS list of files: It monitors them, so if you application changes it during a debug session, VS notices, and wants to make sure it is working with the latest version.

Remove it from the VS list - look at the solution explorer. You may have to copy it back to the original location first, then remove it from the files list

i did not yet proper solution i want use text file as a database...please help me

I wouldn't use a text file as a database - particularly on a website.
Text files are seriously bad at multiuser access, which websites are famed for.
Seriously? I would use a log file, or a simple SQL/MySql database instead, and I wouldn't store HTML code in it either!
Using a text file is leaving yourself open for difficult to replicate errors cropping up far too often - and since you don't do any error checking / trapping your web site will crash on teh user, which is likely to annoy the heck out of him!
