Value
Documentation for this section has not yet been entered.
Remarks
If the System.Data.ParameterDirection is output, and execution of the associated System.Data.Common.DbCommand does not return a value, the System.Data.Common.DbParameter contains a null value.
Output, InputOut, and ReturnValue parameters returned by calling DbCommand.ExecuteReader cannot be accessed until you call DbDataReader.Close or DbDataReader.Dispose on the System.Data.Common.DbDataReader.
