Answer 1

Without regex, you can use this:

Click to copy

public static string GetStringBetweenCharacters(string input, char charFrom, char charTo)
    {
        int posFrom = input.IndexOf(charFrom);
        if (posFrom != -1) //if found char
        {
            int posTo = input.IndexOf(charTo, posFrom + 1);
            if (posTo != -1) //if found char
            {
                return input.Substring(posFrom + 1, posTo - posFrom - 1);
            }
        }

        return string.Empty;
    }

And then:

GetStringBetweenCharacters("\"abc\" <abc@gmail.com>;", '<', '>')

you will get

abc@gmail.com

Click to copy

string input = @"""abc"" <abc@gmail.com>; ""pqr"" <pqr@gmail.com>;";
var output = String.Join(";", Regex.Matches(input, @"\<(.+?)\>")
                                    .Cast<Match>()
                                    .Select(m => m.Groups[1].Value));
