Exemplos

O exemplo a seguir cria um OleDbConnection e define algumas de suas propriedades no cadeia de conexão.

// 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

Comentários

Um valor de 0 não indica nenhum limite e deve ser evitado em um ConnectionString porque uma tentativa de conexão aguardará indefinidamente.
