Question

I am trying to convert an array of Strings containing Dates in string format

 private string[] ex = new string[]{
         "29-06-2017","29-12-2016","30-06-2016","31-12-2015","25-06-2015","24-12-2014","26-06-2014","26-12-2013"};

and I want to cast to decimal array and i used the below code but its not working .

 public void load()
    {
        DateTime[] exDate=Array.ConvertAll(ex, new Converter<string, DateTime>(convertDecimal)); 
        List<DateTime> expiryDate = new List<DateTime>();
        expiryDate.AddRange(exDate);
        expiryDate.Sort();
        _expiryDate=expiryDate;
    }

    public static DateTime convertDecimal(string strgDate)
    {
        return DateTime.Parse(strgDate);
    }

The error I am getting is:

"String was not recognized as a valid DateTime."

Try Converting like this:

public static DateTime convertDecimal(string strgDate)
{
    return DateTime.ParseExact(strgDate, "yyyy-MM-dd",
                    System.Globalization.CultureInfo.InvariantCulture, System.Globalization.DateTimeStyles.None));

}
