my problem is I need to pass this string like this

QUESTID = LuaGetQuestID("QNO_QUEST_AR")

In C#, there are a couple of better ways to do this: you can escape the double quote character:

C#

File.Write("  QUESTID = LuaGetQuestID(\"" + textBox1.Text + "\")\r\n");

Or you can use string interpolation and escape it:

C#

File.Write($"  QUESTID = LuaGetQuestID(\"{textBox1.Text}\")\r\n");

Comment:
You can't include '\r' or '\n' in verbatim strings. The only interpreted character sequences are "double double-quote" for a double quote, and double curly braces for curly braces in verbatim interpolated strings:

C#

PointF p = new PointF(12.3F, 55.9F);
Console.WriteLine(@$"""{p.ToString()}""{\r\n}");

Will give you

"{X=12.3, Y=55.9}"{\r\n}

Or use a verbatim string.

~~Bloody thing ... I'll add that to the solution, so it's easier to read ...~~
My fault - I missed a "/" in the closing tag ... :O

Please don't try to answer your own question. Just add that to the question.
(And don't do it that way.)
