实现

示例

下面的示例创建OleDbConnection并显示其某些只读属性。The following example creates an OleDbConnection and displays some of its read-only properties.

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

Database属性会动态更新。The Database property updates dynamically. 如果使用 SQL 语句或ChangeDatabase方法更改当前数据库,将发送一条信息性消息,并自动更新属性。If you change the current database using a SQL statement or the ChangeDatabase method, an informational message is sent and the property is updated automatically.
