	Depth	Gets a value indicating the depth of nesting for the current row.
	FieldCount	Gets a value indicating the number of columns in the current row.
	IsClosed	Gets a value indicating whether the data reader is closed.
	Item[ ( [ ( Int32] ) ] )	Gets the value of a specified column in its native format, given the ordinal position of the column. In Microsoft Visual C#, this property is the indexer for the T:Microsoft.AnalysisServices.AdomdServer.AdomdDataReader class.
	Item[ ( [ ( String] ) ] )	Gets the value of a specified column in its native format, given the name of the column. In Microsoft Visual C#, this property is the indexer for the AdomdDataReader class.
	RecordsAffected	This member is reserved for future use.

주의

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

To create a 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.
