Extract MM and YYYY from timestamp datacolumn C# ConsoleApplication

Question

I have ODBC DSN connection that I bring into DataTable. Column Three is "TIMESTAMP".

I have...

BRANCH----| TYPE-----| TIMESTAMP

1---------------| R-----------| 14/03/2013 9:42

1---------------| R-----------| 9/01/2015 9:42

3---------------| W-----------| 13/09/2014 9:42

2---------------| R-----------| 1/03/2012 9:42

What I want is:

1---------------| R-----------| 03/2013

1---------------| R-----------| 01/2015

3---------------| W-----------| 09/2014

2---------------| R-----------| 03/2012

There seems to be some good example of this, but i cant find examples that will work on a Datacolumn.

So I use expression quite a bit in my code to truncate etc. That doesnt seem to work in this instance. I mean i have used like this previously

dcUnits.Expression = string.Format("SUBSTRING({0}, 1, 1)+''+{1}+''+{2}", "BRANCH", "TYPE", "ID");

i am not concerned if it is in the same column or a new column added.

thanks for your input :)

If I understood you well, you are having problem with the display of Timestamp column, so if you want to display it in the format MM/yyyy try this:

//Disregard culture info if you are from US
DateTime timeStampedDateTime = DateTime.ParseExact(timeStamp, "dd/MM/yyyy H:mm", CultureInfo.GetCultureInfo("en-US"));
string mmYYYY = timeStampedDateTime.ToString("MM/yyyy", CultureInfo.GetCultureInfo("en-US"));
