C Sharp (C#) - Strings and StringBuilder
You want to create a string that contains both double quotes and backslashes exactly as typed:
She said, "C:\Program Files\".
Which is the correct way to write this string in C#?
Astring s = "She said, \"C:\\Program Files\\\".";
Bstring s = @"She said, "C:\Program Files\".";
Cstring s = "She said, "C:\Program Files\".";
Dstring s = 'She said, "C:\Program Files\".';
Step-by-Step Solution
Solution:
  1. Step 1: Understand escaping double quotes and backslashes

    Double quotes inside normal strings must be escaped with \". Backslashes must be escaped with \\.
  2. Step 2: Analyze options

    string s = "She said, \"C:\\Program Files\\\"."; correctly escapes quotes and backslashes. string s = @"She said, "C:\Program Files\"."; is invalid because verbatim strings require doubling quotes to escape them. string s = "She said, "C:\Program Files\"."; is invalid due to unescaped quotes. string s = 'She said, "C:\Program Files\".'; uses single quotes which are invalid for strings.
  3. Final Answer:

    string s = "She said, \"C:\\Program Files\\\"."; -> Option A
  4. Quick Check:

    Escape quotes with \" and backslashes with \\ in normal strings [OK]
Quick Trick: Escape " as \" and \ as \\ in normal strings [OK]
