Example code snippet for validating dates in ASP.NET: // Validate StateFarmids date format (MM/dd/yyyy) if (!DateTime.TryParseExact(txtStateFarmids.Text.Trim(), "MM/dd/yyyy", CultureInfo.InvariantCulture, DateTimeStyles.None, out DateTime stateFarmidsDate)) { // Show error message lblStateFarmidsError.Text = "Invalid date format. Please enter a valid date in the format MM/dd/yyyy."; return; } // Validate Othertimecardids date format (dd/MM/yyyy) if (!DateTime.TryParseExact(txtOthertimecardids.Text.Trim(), "dd/MM/yyyy", CultureInfo.InvariantCulture, DateTimeStyles.None, out DateTime otherTimeCardIdsDate)) { // Show error message lblOthertimecardidsError.Text = "Invalid date format. Please enter a valid date in the format dd/MM/yyyy."; return; } Thanks

string dateStr = "Apr 12 2023 9:21 AM"; // replace with your actual value string format = "MMM d yyyy h:mm tt"; // specify the expected date format DateTime date; if (DateTime.TryParseExact(dateStr, format, CultureInfo.InvariantCulture, DateTimeStyles.None, out date)) { // date is valid, do something } else { // date is invalid, handle error }
