How to validate if string is a date in specific format?

I have list of dates formats. I want to verify that in my app, specific string is changed according the format selected in settings.

Hi,

I would try something like this:

Code: Select all

		using System.Globalization;
		/// <summary>
		/// validate date format
		/// </summary>
		/// <param name="dateString">date string</param>
		/// <param name="dateFormatString">expected date format</param>
		public void ValidateDateFormat(string dateString, string dateFormatString)
		{
			try
			{
				System.DateTime dt = System.DateTime.ParseExact(dateString, dateFormatString, System.Globalization.CultureInfo.InvariantCulture);
			}
			catch
			{
				Report.Log(ReportLevel.Failure, "Validated date in incorrect format. \r\nValidated date: " + dateString + "\r\nValidated date format: " + dateFormatString);
			}
		}

Simply, pass the date and expected format to above method and if date is incorrect in format, ParseExact fails and so it logs failure in Ranorex report. Hope this helps?
