class Program
{
  static void Main()
	{
	// Input string.
	const string example = "Name:\r\n\r\nEmail:  [email protected]\r\n\r\nPhone:  333-343-0909\r\n\r\n";

	// Get a collection of matches with the Multiline option.
	//MatchCollection matches = Regex.Matches(example, "^(.+)$", RegexOptions.Multiline);
	MatchCollection matches = Regex.Matches(example, "^Name:([^\\n]*)$", RegexOptions.Multiline);
	foreach (Match match in matches)
	{
		// Loop through captures.
		foreach (Capture capture in match.Captures)
		{
		// Display them.
		Console.WriteLine("--" + capture.Value);
		}
	}
	}
}

Seems like your capturing group should be something like (\S[^\r\n]*$) -- ensure that there's a non-whitespace character, and then continue to match characters that aren't the known terminators.

Updated to something that works, but will capture the leading whitespace in front of a name. Should be stripped out later.
