C# DateTime.ParseExact produces wrong dates

Question

I'm trying to parse a date string in the form dd/mm/yyyy but I keep getting a consistent yet invalid results. What am I doing wrong?

here's the code and it's input

DateTime.ParseExact("23/09/2018","d/m/yyyy",CultureInfo.InvariantCulture) => 1/23/18

DateTime.ParseExact("8/10/2018","d/m/yyyy",CultureInfo.InvariantCulture) => 1/8/18

DateTime.ParseExact("30/04/2018","d/m/yyyy",CultureInfo.InvariantCulture) => 1/30/18

I've tried using CultureInfo.GetCultureInfo("en-UK"), CultureInfo.GetCultureInfo("en-GH") but still same results.

I've tried using "dd/mm/yyyy" still same results.

I've also tried qouting the slashed as described here but still same results.

Use uppercase M for month. Lowercase is for minutes. – John Wu Sep 23 '18 at 16:30 — John Wu, Sep 23 '18 at 16:30

Try this:

DateTime.ParseExact("23/09/2018","dd/MM/yyyy",CultureInfo.InvariantCulture)

MM/M is used to parse months, mm/m is used for minutes.

In C# 'M' is used for month and 'm' used for minute, Here you can find all details.

So please try:

   Console.WriteLine(DateTime.ParseExact("8/10/2018","d/M/yyyy",System.Globalization.CultureInfo.InvariantCulture));

Small 'm' stands for minutes, try 'M' or 'MM' for months
