OleDbCommand.Connection Property

Gets or sets the OleDbConnection used by this instance of the OleDbCommand.

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

public OleDbConnection Connection { get; set; 
/** @property */
public OleDbConnection get_Connection ()

/** @property */
public void set_Connection (OleDbConnection value)

public function get Connection () : OleDbConnection

public function set Connection (value : OleDbConnection)

Property Value

The connection to a data source. The default value is a null reference (Nothing in Visual Basic).

Exception typeCondition

InvalidOperationException

The Connection property was changed while a transaction was in progress.

You cannot set the Connection, CommandType and CommandText properties if the current connection is performing an execute or fetch operation.

If you set Connection while a transaction is in progress and the Transaction property is not null, an InvalidOperationException is generated. If the Transaction property is not null and the transaction has already been committed or rolled back, Transaction is set to null.

The following example creates an OleDbCommand and sets some of its properties.

public void CreateOleDbCommand() 
{
   string queryString = "SELECT * FROM Categories ORDER BY CategoryID";
   OleDbCommand command = new OleDbCommand(queryString);
   command.Connection = new OleDbConnection
      ("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=NWIND_RW.MDB");
   command.CommandTimeout = 20;
