Question

Consider this code:

TimeStamp.Text = BlogComment.Date.UtcNow.ToString("yyyy-MM-ddTHH\:mm\:ss.fffffffzzz");

BlogComment.Date is a DateTime object with its date set. TimeStamp is just a literal.

I keep getting unrecognised escape sequence. How can I fix this problem?

Answer 1

You want a string literal – prefixing a string with @ will not parse the string for escape sequences like you have in your string but take it in “literal” form.

@"yyyy-MM-ddTHH\:mm\:ss.fffffffzzz"

Edit:

Also there is no UtNow property on DateTime – this is a static property only available on the DateTime class. You can just write:

TimeStamp.Text = BlogComment.Date.ToString(@"yyyy-MM-ddTHH\:mm\:ss.fffffffzzz");

or if your intention was to convert the time to UTC:

TimeStamp.Text = BlogComment.Date
                            .ToUniversalTime()
                            .ToString(@"yyyy-MM-ddTHH\:mm\:ss.fffffffzzz");
