EntityDataReader::Close Method ()

Implements

SQL Server puts output parameters from stored procedures at the end of the result stream, after all the result sets. Therefore, to get output parameter values, an application must consume all the records in all the result sets. If the application closes the EntityDataReader (which would also close the DbDataReader), output parameters might not be populated.

EntityDataReader does not implicitly consume result sets to make output parameters available. Therefore, note the following:

• EntityDataReader calls the DbDataReader::NextResult only when EntityDataReader::NextResult is explicitly called. If DbDataReader::NextResult throws an exception, EntityDataReader will wrap it in EntityException (or a derived exception).

• Close only closes the DbDataReader, without consuming any pending records or result sets.

• M:System.Data.EntityClient.EntityDataReader.Dispose only disposes of the DbDataReader, without consuming any pending records or result sets.
