Regex printing newlines C#

I am using Regex to return two lines of text, but it returns newlines with additional text.

//Text is located in txt file and contains
I've been meaning to talk with you.
I've been meaning to talk with you.
I've been meaning to talk with you.

string text = File.ReadAllText(@"C:\...\1.txt");

Regex unit = new Regex(@"(?<Text>.+(\r\n){1}.+)");
MatchCollection mc = unit.Matches(text);
    foreach (Match m in mc)
         foreach (Group g in m.Groups)
              Console.WriteLine(g.Value);

enter image description here

You may use

var m = Regex.Match(text, @"^.+(?:\n.+)?");
if (m.Success) 
{
    Console.Write(m.Value.Trim());
}

Details

  • ^ - start of string
  • .+ - any 1+ chars other than an LF symbol
  • (?:\n.+)? - an optional sequence of:
    • \n - a newline
    • .+ - any 1+ chars other than an LF symbol

The .Trim() is used here to trim the result from a possible CR symbol (since in .NET regex, . also matches CR symbol.
