I'm trying to extract the domain name from an email address. For example if an email address is info@mydomain.com i want to extract 'mydomain' from the string.
I have some C# code which does this:
[Code]....
This works fine - except if a user has an email address which contains a dot '.' (e.g. fname.lname@mydomain.com) then it throws the following error:
Length cannot be less than zero.Parameter name: length
Line 29: int startIndex = strEmail.IndexOf("@");Line 30: int endIndex = strEmail.IndexOf(".") - startIndex;Line 31: string domain = strEmail.Substring(startIndex + 1, endIndex - 1);
The problem is the first '.' in the email address is causing it to calculate the string from the incorrect position.
Is there a way to retify this - or does anyone know of another solution to extract the domain name from an email address?

I am building an email feature in my website (jobs site). By using this functionality, recruiters will be able to send emails to candidates. I want an option so that the user can also set 'From Address' and the email should be ANTI-SPAM compliant.
In addition to the process of regex syntax validation of Email Addresses entered by users, I'm trying to check if the entered email address is a real one and does exist?The best I could achieve is to "Ping" the host the email address is associated with. But there are some other terms in the industry like Handshaking with Email Server, etc.not necessarily with 100% confirmation accurary!

I have a need to poll a mail server and then extract a photo that is either embedded or attached to the email message.The goal is to extract the photo and save it to a disk file. The desired functionality is much like emailing a photo from your phone to Twitter, Flickr, etc.
I have to automate a program where whenever I receive an email with header "Item Number change: Rice 2 lbs" and the message says "Price for item 10023456 has been changed to $2.99"
I would like to extract this kind of specific emails from my emails and then extract item number (100023456) and price (2.99) and store it into temporary table or session and use this information to change the value in the database. Instead of opening database manually and change the price.
