String was not recognized as a valid DateTime format

Question

Hi

  I am trying to upload data but it is giving above error

DateTime StartTime = DateTime.Now;String Time = colum[2].ToString();String DT1 = colum[1].ToString() + " " + Time;DateTime StartDate = DateTime.ParseExact(DT1, "dd-MM-yyyy HH:mm", System.Globalization.CultureInfo.InvariantCulture);StartTime = Convert.ToDateTime(StartDate.ToString("yyyy-MM-dd HH:mm"));

Below is the Excel Data

col1	Col2	Col3
13	01/04/2022	14:30
18	02/04/2022	16:00
13	03/04/2022	17:15

Thanks
