How to format a date from Oracle to a valid DateTime in c#?
So... the oracle format string is a bit different from the C# DateTime format string, so I can't use that format-string as an argument for the parse. I am using Devart/CoreLab but their OracleDate.Parse seems to be really strange and not working for me. How can I parse it correctly? Do I have to call a query to the db with a TO_DATE/TO_CHAR just to get a conversion? Or that I have to map each oracle format string element into a C# format string element?
edit: And the format string of Oracle and C# are different, such as MON instead of MMM...
edit2: more clarification: Basically I would have strings that are oracle-date-in-string, e.g. "08-OCT-85", and I am also able to get the oracle format pattern that these date string is following, such as "DD-MON-YY", "DD-MON-RR", "YYYY/RM/DD"... etc
I would like to be able to parse them into a C# DateTime properly so that I can set them to Parameter (which expects C# DateTime), and the problem is these oracle-date-format-pattern is not the same as the C# DateTime-parse-format-pattern.
I suspect somewhere out there might exist some function that can do something like
DateTime dt = ParseDatestringWithSpecifiedOracleDatePatternIntoCSharpDateTime("08-OCT-85", "DD-MON-YY);
right? But I can't find it yet :(

Try:
DateTime.ParseExact("08-OCT-85", "dd-MMM-yy", System.Globalization.CultureInfo.InvariantCulture)
