Datetime Conversion in C#

Question

I receiving dates in the USA standard format mm/dd/yy .

I can upload to MySQL only in the format of yyyy-MM-dd .

How can you convert mm/dd/yy format to yyyy-MM-dd format in C#?

Answer 1

You could parse it and then format it. ( DateTime.ParseExact , DateTime.ToString )

However, you shouldn't have to reformat for MySQL's benefit, and it suggests your database access is inappropriate:

• Your database column should be a DATETIME column or something similar, if you're storing dates in it
• Your database code shouldn't be including the value as a string at all. It should be passing it as a parameter with a DateTime value

So using parameterized SQL, you should just need to parse (eg using DateTime.ParseExact ), then pass it up as a DateTime :

DateTime date = DateTime.ParseExact(text, "mm/dd/yy",
                                    CultureInfo.InvariantCulture);
command.Parameters.Add("@Foo", MySqlDbType.DateTime).Value = date;

Answer 3

You can use MySQLs STR_TO_DATE(str,format) function.
Or you can use string formatting in c#

Answer 4

Something like this should work:

DateTime dt = Convert.ToDateTime(dateString);
string newDateString = dt.ToString("yyyy-MM-dd");
