Check if a string contains date or not

Question

Given a string "15:30:20" and "2011-09-02 15:30:20", How can I dynamically check if a given string contains date or not?

"15:30:20" -> Not Valid

"2011-09-02 15:30:20" => Valid

Answer 1

Use this method to check if string is date or not:

    private bool CheckDate(String date)
    {
        try
        {
            DateTime dt = DateTime.Parse(date);
            return true;
        }
        catch
        {
            return false;
        }
    }

You can use

bool b = DateTime.TryParseExact("15:30:20", "yyyy-MM-dd HH:mm:ss",CultureInfo.InvariantCulture,DateTimeStyles.AssumeLocal,out datetime);

To check if a string is parsable into DateTime.
