I want to load an url as a string, and then use regex to write out matches in c#.
Downloading an URL as a string is easy using System.Net.WebClient.DownloadString.
Finding matches in the HTML is easy using System.Text.RegularExpressions.Regex.Match.
Both links have good examples on usage.
It's really not a good idea to use regular expressions to match content in HTML. Better is to use regular expressions to match tokens in HTML, and parse it. But then, at that point, you might as well use an existing parser.

I dont know how to use regex ,i have seen them to be used in email validation ,Is there any way i could restrict null values by using regular expression
/^(.+)$/
This regex will match anything which isn't empty (require one or more character), but is it really usefull to check it with a regex ?
The answer is no. null is not a value. It indicates you that the pointer doesn't point to anything. You can use "assert", or just if(yourobject==null){}

I'm looking at generating web-documents at runtime. This means generating the html, and JavaScript and css. Are there any advanced libraries? Or am I going to be going at by creating the html document with File.Create("Default.aspx") and then lots of HtmlTextWriter.WriteBlaBlaBla()
Your business requirement seems unclear but try using HTMLtextwriter to have more control over your code

I need to make a routine in c# that takes an MS outlook email (which will have tables inside it) and extract the tables contents to a txt file or csv file.
I don't really know where to start with this.
Could any body tell me how or where to start with this?
If you already figured out how to get the HTML from the email, you can use HTML Agility Pack to parse it and extract what you need.
You can install the Pack using Nuget.

I've made games with c# but have never done anything with networking or accessing a website via c#, so I was wondering how I would be able to search twitter post for certain keywords, counting how many come up but are recent post. Thank you very much.
I suggest that you'll check Linq to Twitter:

This website should get you on the right track with searching inside a post with Linq To Twitter:

I m doing a project which invoves extracting the semantics of a word. While doing some resaerch I found out it's better to get Synonyms of a word rather than trying to extract semantics.
What is the best way of doing this. I only need to get the synonym of a word.
Please help.
Find a thesaurus. Pay attention to its licensing. E.g., Roget's Thesaurus. There may be one that is better-suited to being parsed programmatically.
Parse the thesaurus. For example, you could might store it in a Dictionary<string,List<string>>.
Look up entries as needed. How this is done depends on what data structure you stored it in. It's pretty easy in a Dictionary.
If you have trouble with a specific step in this process, feel free to ask. Your question is a bit too open-ending for me to know exactly what part to focus on.
