You're assuming that your code will only ever be passed email addresses that end with .com; what about other top-level domains?

For example, .co is a valid TLD, associated with Colombia. If you were passed billy@test.comike@test.biz, you'd have no way of knowing whether that was "billy@test.com" and "ike@test.biz", or "billy@test.co" and "mike@test.biz".

The only correct solution is to fix how the email addresses are passed to your application.

He might find String.Split to be more helpful :)

Kornfeld Eliyahu Peter[^] is right. Check OP's requirements.


string stremails = "nitya@gmail.combhavya@gmail.com";

stremails = stremails.Replace(".com", ".com,");

var emails = stremails.Split(new string[]{","}, StringSplitOptions.RemoveEmptyEntries);

foreach(string e in emails)
{
	Console.WriteLine(e);
}

Maybe - It is not clear what OP wants to do with the data after adding the separator...
Let OP decide :-)...
