Exemples

L’exemple suivant crée un OleDbConnection et définit certaines de ses propriétés dans la chaîne de connexion.The following example creates an OleDbConnection and sets some of its properties in the connection string.

// The connectionString argument contains the Connect Timeout 
// keywords, as follows: "... ;Connect Timeout=30;"
public void InsertRow(string connectionString, string insertSQL)
{
    using (OleDbConnection connection = new OleDbConnection(connectionString))
    {
        // The insertSQL string contains a SQL statement that
        // inserts a new row in the source table.
        OleDbCommand command = new OleDbCommand(insertSQL);

        // Set the Connection to the new OleDbConnection.
        command.Connection = connection;

        // Open the connection and execute the insert command.
        try
        {
            connection.Open();
            command.ExecuteNonQuery();
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
        }
        // The connection is automatically closed when the
        // code exits the using block.
    }
}
' The connectionString argument contains the Connect Timeout 
' keywords, as follows: "... ;Connect Timeout=30;"
Public Sub InsertRow(ByVal connectionString As String, _
    ByVal insertSQL As String)

    Using connection As New OleDbConnection(connectionString)
        ' The insertSQL string contains a SQL statement that
        ' inserts a new row in the source table.
        Dim command As New OleDbCommand(insertSQL)

        ' Set the Connection to the new OleDbConnection.
        command.Connection = connection

        ' Open the connection and execute the insert command.
        Try
            connection.Open()
            command.ExecuteNonQuery()
        Catch ex As Exception
            Console.WriteLine(ex.Message)
        End Try
        ' The connection is automatically closed when the
        ' code exits the Using block.
    End Using
End Sub

Remarques

La valeur 0 indique aucune limite et doivent être évitée dans un ConnectionString , car une tentative de connexion attend indéfiniment.A value of 0 indicates no limit, and should be avoided in a ConnectionString because an attempt to connect will wait indefinitely.
