Regarding your case, it seems that you are getting an incorrect value in your startDate which could be: 03/29/2020 - 04/04/2020. If that is the case, you can do something like:

using System;

public class Program
{
    public static void Main()
    {
        DateTime dateTime;
        DateTime dateTime1;
        DateTime dateTime2;

        string start = "03/29/2020";
        string incorrectdate=@"03/29/2020 - 04/04/2020";
        string[] parsed=incorrectdate.Split('-');
        dateTime = DateTime.Parse(start);
        dateTime1=DateTime.Parse(parsed[0]);
        dateTime2=DateTime.Parse(parsed[1]);
        Console.WriteLine(dateTime);
        Console.WriteLine(dateTime1);
        Console.WriteLine(dateTime2);
    }
}

Output:

3/29/2020 12:00:00 AM
3/29/2020 12:00:00 AM
4/4/2020 12:00:00 AM
