OleDbCommand.ExecuteReader Method

Sends the CommandText to the Connection and builds an OleDbDataReader.

Namespace:  System.Data.OleDb
Assembly:  System.Data (in System.Data.dll)

member ExecuteReader : unit -> OleDbDataReader

ExceptionCondition
InvalidOperationException

Cannot execute a command within a transaction context that differs from the context in which the connection was originally enlisted.

When the CommandType property is set to StoredProcedure, the CommandText property should be set to the name of the stored procedure. The command executes this stored procedure when you call ExecuteReader.

Before you close the OleDbConnection, first close the OleDbDataReader object. You must also close the OleDbDataReader object if you plan to reuse an OleDbCommand object.

The following example creates an OleDbCommand, and then executes it by passing a string that is an SQL SELECT statement, and a string to use to connect to the data source.
