javascript regex to c# : I have a regex for validating Email Ids.
^(([\w]+(\.[^<>()\[\]\\.,;:\s@"]+)*)|(".+"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}])|([0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3})|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$

I need to convert it C# format.Can any one help?What are the changes needed on the above JS Regex?
