Article
10/22/2007

Gets or sets the SqlCeConnection used by this instance of the SqlCeCommand.

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

Syntax

'Declaration
Public Property Connection As SqlCeConnection
'Usage
Dim instance As SqlCeCommand
Dim value As SqlCeConnection

value = instance.Connection

instance.Connection = value

public SqlCeConnection Connection { get; set;

public:
property SqlCeConnection^ Connection {
    SqlCeConnection^ get ();
    void set (SqlCeConnection^ value);

/** @property */
public SqlCeConnection get_Connection ()

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

public function get Connection () : SqlCeConnection

public function set Connection (value : SqlCeConnection)

Property Value

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

Exceptions

Exception type	Condition
InvalidOperationException	The Connection property was changed while a transaction was in progress.

Remarks

SQL Server Mobile supports multiple simultaneous connections as well as multiple commands sharing the same connection. Thus, it is possible to have multiple instances of SqlCeDataReader open on the same connection. This behavior differs from that of System.Data.SqlClient.

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 a null reference (Nothing in Visual Basic), an InvalidOperationException is generated. If the Transaction property is not a null reference (Nothing in Visual Basic) and the transaction has already been committed or rolled back, Transaction is set to a null reference (Nothing in Visual Basic).

Example

The following example creates a SqlCeCommand and sets the Connection property to a SqlCeConnection object.

Dim queryText As String = "SELECT * FROM Categories ORDER BY [Category ID]"
Dim cmd As New SqlCeCommand(queryText)

cmd.Connection = conn
cmd.CommandType = CommandType.Text

string queryText = "SELECT * FROM Categories ORDER BY [Category ID]";
SqlCeCommand cmd = new SqlCeCommand(queryText);

cmd.Connection = conn;
cmd.CommandType = CommandType.Text;
