How to convert char array into string for DateTime.Parse?

Question

I am using this in my controller:

char[] arrDate = date.ToArray();
DateTime dt = DateTime.Parse(arrDate[0] + arrDate[1] + "/" +
                             arrDate[2] + arrDate[3] + "/" +
                             arrDate[4] + arrDate[5] + arrDate[6] + arrDate[7]);

The error:

System.FormatException: String was not recognized as a valid DateTime.

Answer 1

Consider this:

var date = "11252017";
var arrDate = date.ToArray();
var strDate = arrDate[0] + arrDate[1] + "/" +
              arrDate[2] + arrDate[3] + "/" +
              arrDate[4] + arrDate[5] + arrDate[6] + arrDate[7]; // 98/25/2017

Notice that:

• '1' + '1' = 98* ⇒ char + char = int
• 98 + "/" = "98/" ⇒ int + string = string
• "98/" + '2' = "98/2" ⇒ string + char = string

The fix:

var dt = DateTime.Parse("" +
                        arrDate[0] + arrDate[1] + "/" +
                        arrDate[2] + arrDate[3] + "/" +
                        arrDate[4] + arrDate[5] + arrDate[6] + arrDate[7]);

*ASCII representation:

• '1' in decimal is 49
