Explain MySQL database and asp.net how to combine powerful

Due to competitive prices and ease of use, MySQL is gradually upgrading its market share. The open source community has developed to extend the scope of MySQL usage. NET Framework (. NET Framework) is a database connector that can be used in the. Let's learn how to do it in. NET applications, using MySQL.

Data consolidation with. Net

The MySQL community has developed a MySQL data interface that provides basic functionality for connecting data sources and program code. On the Windows platform, like the following MySQL connector:

* MySQL Connector/net 1.0 (previously known as Bytefx.data): is an open source. Net Data interface designed for MySQL. It was developed entirely in C # and we can find it on the mysql.com website. (Note: In the example of this article, we use the MySQL connector/net 1.0 data interface to connect to the database, which can be easily installed with Windows Installer, with code instances and documents included.) ）

* mysqldirect. NET data Provider: A commercial data interface developed by Core Lab. His price is determined by the type of license purchased, but we can download its trial version.

If you use Mono, you can find the download of the PHP connector on the Mono website. If you run mono on a Windows platform, the connectors you download include the installer. If not, then download the appropriate connector based on the type of operating system you are using.

Using the MySQL Data interface

Once you have installed the MySQL data interface, you must introduce it into your code to use it. You can use the MySql.Data.MySqlClient namespace to connect to the MYSQL server. In C #, you can use a using statement to introduce the MySQL data interface:

Using MySql.Data.MySqlClient;

Alternatively, you can introduce the MySQL data interface in a asp.net Web Form (Web Form) by using Import directives:

Alternatively, you can write the full path of a class in your code while using the namespace, but that would waste more bytes than importing more characters using the import directive. Once we have specified a name space, we can interact with the MySQL database for data. MySql.Data.MySqlClient This namespace provides a number of classes for handling MySQL data. Here is a sample of these classes:

* Mysqlconnection: Manage the connection with MySQL server/database;

* Mysqldataadapter: A set of commands and connections for populating dataset objects and updating MySQL databases;

* Mysqldatareader: Allows you to read data from a MySQL database. It is a one-way flow of data;

* Mysqlcommand: Provides the function of sending instructions to the database server;

* Mysqlexception: Provides exception handling when a problem occurs.
