Notepad, no kidding? (Notepad is Microsoft application, totally stand-along, not communication with any other in any way... in case you don't know what is it.)

Did you mean data from a textfile? Otherwise getting data from notepad could be interesting...

code for collecting data from excel will do.. textfile or notepad would be an added advantage.

What would it mean: "text file or notepad"?

Use regex to parse the text.

C#

using System.Text.RegularExpressions;
...
string input="someone@somedomain.com.au is an email address... and someone@anotherdomain.com is yet another one.";
string pattern="\\b[\\w\\.-]+@[\\w\\.-]+\\.\\w{2,4}\\b";
var matches =Regex.Matches( input,pattern);
string[] addresses = matches.OfType<match>().Select(m => m.Value).ToArray();

your input string would be the contents of your text file or in the case of excel you could read each cell into a StringBuilder variable.
