주의

The AdomdDataReader class is the implementation of the System.Data.IDataReader interface for ADOMD.NET. All Microsoft .NET Framework data providers implement the System.Data.IDataReader interface as a way of quickly reading forward-only result sets.

To create an AdomdDataReader, you must call the ExecuteReader method of the AdomdCommand, rather than directly using a constructor.

While the AdomdDataReader is in use, the AdomdCommand and the associated AdomdConnection is busy serving the AdomdDataReader. While in this state, no operations can be performed on the AdomdConnection or AdomdCommand objects other than closing them. This remains the case until the Close or Dispose method of the AdomdDataReader is called. Changes made to a result set by another process or thread while data is being read may be visible to the user of the AdomdDataReader. However, the precise behavior is timing dependent.

IsClosed and RecordsAffected are the only properties that you can call after the AdomdDataReader is closed.
