c# - Inserting a date/time value in Access using an OleDbParameter

I'm trying to do an insert in oledb(ms access database) the field called objectdate is date/time

the code i use to add the parameter is this, but i'm getting error.

  OleDbParameter objectdate = new OleDbParameter("@objectdate", OleDbType.DBDate);
  objectdate.Value = DateTime.Now; cmd.Parameters.Add(objectdate);

the error:

Data type mismatch in criteria expression.

OleDB doesn't like milliseconds in the datetime parameters. If you remove the milliseconds it will go ok. See also: How to truncate milliseconds off of a .NET DateTime.
