示例

以下示例创建 并 OleDbConnection 显示其一些只读属性。

static void OpenConnection(string connectionString)
{
   using (OleDbConnection connection = new OleDbConnection(connectionString))
   {
      try
      {
         connection.Open();
         Console.WriteLine("ServerVersion: {0} \nDatabase: {1}",
             connection.ServerVersion, connection.Database);
      }
      catch (Exception ex)
      {
         Console.WriteLine(ex.Message);
      }
      // The connection is automatically closed when the
      // code exits the using block.
   }
}

Public Sub OpenConnection(ByVal connectionString As String)

   Using connection As New OleDbConnection(connectionString)
      Try
         connection.Open()
         Console.WriteLine("Server Version: {0} Database: {1}", _
             connection.ServerVersion, connection.Database)
      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

注解

属性 Database 动态更新。 如果使用 SQL 语句或 ChangeDatabase 方法更改当前数据库，则会发送一条信息性消息，并自动更新 属性。
