概述

dotConnect for MySQL（以前稱為My..NET）是一個增強(qiáng)型的支持ORM的MySQL數(shù)據(jù)提供程序，它基于ADO.NET技術(shù)構(gòu)建以提供用于開發(fā)基于MySQL的數(shù)據(jù)庫應(yīng)用程序的完整解決方案。它介紹了設(shè)計應(yīng)用程序體系結(jié)構(gòu)的新方法，提高了生產(chǎn)率，并利用了數(shù)據(jù)庫應(yīng)用程序。

快速高級ADO.NET提供程序

dotConnect for MySQL提供了到MySQL數(shù)據(jù)庫的高性能連接以及許多創(chuàng)新的開發(fā)工具和技術(shù)。它支持各種MySQL特定的特性，例如安全的SSL和SSH連接、嵌入式服務(wù)器、壓縮協(xié)議、HTTP隧道等等。

RAD方法

dotConnect for MySQL提供了大量GUI工具，提高了您的工作效率。它集成到Visual Studio Server Explorer和其他工具中，并提供高級可視化組件編輯器來簡化組件調(diào)整。DataSet工具，例如DataSet Wizard、DataSet Editor、DataSet Manager，為您提供了創(chuàng)建和編輯有類型和無類型數(shù)據(jù)集的簡單方法。

ORM解決方案

dotConnect for MySQL提供了增強(qiáng)的ORM支持，并為ORM模型提供了捆綁的可視化設(shè)計器——實體開發(fā)器。dotConnect for MySQL支持ADO.NET實體框架、NHibernate和LinqConnect（以前稱為LINQ to MySQL）——我們自己的ORM解決方案，與Microsoft LINQ to SQL緊密兼容，同時用自己的特性擴(kuò)展其功能。

特征

直接模式

允許您的應(yīng)用程序直接通過TCP/IP使用MySQL，而不涉及MySQL客戶端庫。

企業(yè)圖書館

可以與Microsoft企業(yè)庫數(shù)據(jù)訪問應(yīng)用程序塊一起使用。

監(jiān)測

允許使用免費(fèi)的dbMonitor應(yīng)用程序?qū)?shù)據(jù)庫事件進(jìn)行每組件跟蹤。

ASP.NET

實現(xiàn)角色、會話狀態(tài)、成員、配置文件、站點地圖和其他ASP 2.0提供程序。

BIS

使Integration Services能夠向MySQL服務(wù)器導(dǎo)出和導(dǎo)入數(shù)據(jù)。

兼容性

在.NET和.NET Compact Framework 2.0及更高版本、.NET Core和Mono上支持MySQL服務(wù)器3.23及更高版本。

dotConnect for MySQL is data provider to direct access to MySQL database server for the Microsoft .NET Framework and .NET Compact Framework. It is completely based on ActiveX Data Objects for the .NET Framework (ADO.NET) technology. ADO.NET provides a rich set of components for creating distributed, data-sharing applications. It is an integral part of the .NET Framework, providing access to relational data, XML, and application data.

MySQLDirect .NET data provider is designed to be lightweight. It consists of a minimal layer between MySQL database and your code. This extends functionality without sacrificing performance.

There are core classes that make up MySQLDirect .NET data provider. The following table describes those classes and their functions.

• MySqlConnection - Establishes a connection to MySQL database and can begin a transaction.
• MySqlCommand - Executes SQL statements at MySQL database, and exposes parameters.
• MySqlDataReader - Exposes and reads a forward-only stream of data from MySQL database.
• MySqlDataAdapter - Populates a DataSet and resolves updates with MySQL database.
• MySqlTransaction - Enables you to enlist commands in transactions at MySQL database.
• MySqlParameter - Defines input, output, and return value parameters for commands.

MySqlException - Returned when an error is encountered at MySQL database. For an error encountered at the client, MySQLDirect .NET data provider throws a .NET Framework exception.

Along with the core classes listed in the preceding table, MySQLDirect .NET data provider also contains the classes extending its base functionality and allowing to accomplish additional tasks.

• MySqlCommandBuilder - A helper object that will automatically generate command properties of MySqlDataAdapter and populate the MySqlParameters collection of MySqlCommand object.
• MySqlDataTable - Provides all of the functionality needed to retrieve and manipulate data from a MySQL server data source.
• MySqlScript - Serves to execute series of SQL statements separated by special symbols.
• MySqlLoader - Serves to load external data into the MySQL database.
• MySqlDump - Serves to store a database or its parts as a script and also to restore database from the received script.
• MySqlMonitor - Allows to monitor dynamic SQL execution in applications that use MySQLDirect .NET.
