Convert a string containing monthName to Int of MonthDigit

Question

I have a string which has short month name in it.\

string month = "Jun";

I need to get month in digit from this month name.

Say i do this:

int monthInDigit = getMonth(month);

monthInDigit <-- 6

How can i achieve this. If you cant get my question pleases comment i will explain it proprly.

Thanxx in advance

@SonerGönül, I would assume because June is the 6th month in the year. — Arran, Oct 07 '13 at 08:39

int monthInDigit = DateTime.ParseExact(month, "MMM", CultureInfo.InvariantCulture).Month;

Why did u passed null as the last parameter – Murtaza Munshi Oct 07 '13 at 08:47

@ArsenMkrt: That's not true. If `DateTime.ParseExact` works depends on OP's current culture. If you pass `null` as third parameter you use `CultureInfo.CurrentCulture`. That's why i have used `CultureInfo.InvariantCulture` in my answer. Not every language abbreviates `June` with `Jun`. – Tim Schmelter Oct 07 '13 at 09:45
@TimSchmelter Thanxxx for the extra info and correcting the null paramter information. – Murtaza Munshi Oct 07 '13 at 09:57

You can parse it to a DateTime first:

DateTime dt = DateTime.ParseExact("Jun", "MMM", CultureInfo.InvariantCulture);
int month = dt.Month;
if(month < 6)
{  
    // do something...
}

@MurtazaMunshi: Use `CultureInfo.InvariantCulture` instead of `null` if you want it to work in any culture. – Tim Schmelter Oct 07 '13 at 09:50
What if it's June or September? What should the `MMM` be replaced with? Thanks. – Si8 Oct 24 '16 at 14:50

@Si8: if it's not the abbreviated month name but the full name use `MMMM` – Tim Schmelter Oct 24 '16 at 14:51
For day that can have `1` or `15` I tried using "dd" but it fails for the `1`. – Si8 Oct 24 '16 at 15:04
What should I use for the day? Thank you. – Si8 Oct 24 '16 at 15:05
@Si8: if `1` is possible then use `d` instead of `dd`. This reading is for you: https://msdn.microsoft.com/en-us/library/8kb3ddd4(v=vs.110).aspx – Tim Schmelter Oct 24 '16 at 15:31
It was failing for me. I had to end up using `PadLeft` to add leading 0 before it worked. So weird. – Si8 Oct 24 '16 at 15:35

another way :

string [] arr= {jun, fab,...}; 

public int getMonth(string month){

for(int i = 0 ; i< arr.length ; i++){
   if(string[i].Contains(month) || month.Contains(arr[i]))
   return i+1;
   }

return -1;// if month is invalid , return -1
}
