For the first date: string.Format("The current date and time is {0}.", DateTime.Now) For the second string.Format("The current date and time is {0:f}.", DateTime.Now)

Remember for the third question, "I like apples" that the first item is "0" not "1": string.Format("I like {0} and {1}, but I don't like {2}.", "apples", "oranges", "bananas")

Without knowing which question is troubling you, here's some basic hints:

  • the questions all involve putting placeholders in the string for formatting.
  • basic placeholders have the format "{n}" where the n is the placeholder number (starting with 0)
  • special placeholders have the format "{n:f}" where f is a format specifier

While custom formats would work in actual practice, I think the challenge is expecting you to use the standard single-letter format specifiers.

You can find them used in the videos, or in the official MSDN Documentation.

Thanks Steven! There are two actually: To fill the blank, the resolution can be a lot but the system does not allow me to pass them (I guess the system is byte-by-byte comparism to its unique answer).

  1. Complete the following code in order to produce a string that prints the current date.

string.Format("The current date is _____________________", DateTime.Now.Date)

i.e. if I fill {0:MM/dd/yy}, it reports error.

  1. Complete the following code in order to produce a string that prints the current date and time, but formatted as a full date/time pattern (short time) like so: "The current date and time is Monday, June 15, 2009 1:45 PM"

string.Format("The current date and time is _____________________", DateTime.Now)

i.e. if I fill {0:dddd, mm yyyy H:mm:ss}, it reports error as well.....
