How to use MySql database in. net Environment

I have read an article about Asp.net and mysql on the Internet. For details about how to install mysql and connect to the MySQL database in. NET, see ASP. NET + MySQL simple illustration getting started.

Here I use EMS Mysql Manager lite tool to manage mysql5.0
:

Here, my database and table have been created. Now open vs. net2003 and create a project named mysqltest.

Now we have installed MySQL Connector/Net

For specific installation method, please see ASP. NET + MySQL simple illustration entry "http://www.yesky.com/431/1944431.shtml

If it is installed by default, you can go to C: \ Program Files \ MySQL Connector Net 1.0.4 \ bin \. NET 1.1 \ find MySql. data. dll, and then copy it to the bin directory under the mysqltest directory

Right-click the data in the toolbox and choose Add/Remove from the shortcut menu.

For example

Select Browse. Under the bin directory of the mysqltest project, select MySql. Data. dll

Reference MySql. Data. dll in the bin directory of the mysqltest project in solution Manager

Add the DataGrid Control to the aspx page

Here is the C # code

Using System. Data;

Using System. Drawing;

Using System. Web;

Using System. Web. SessionState;

Using System. Web. UI;

Using System. Web. UI. WebControls;

Using System. Web. UI. HtmlControls;

Using MySql. Data. MySqlClient;

Namespace mysqltest

{

/// <Summary>

/// Summary of WebForm1.

/// </Summary>

Public class WebForm1: System. Web. UI. Page

{

Protected System. Web. UI. WebControls. DataGrid DataGrid1;

Private void Page_Load (object sender, System. EventArgs e)

{

// Place user code here to initialize the page

MySqlConnection MyConn = new MySqlConnection ("Server = localhost; userid = root; password =; Database = guestbook ");

String SQL = "select * from guestbook ";

MySqlDataAdapter Myda = new MySqlDataAdapter (SQL, MyConn );

DataSet ds = new DataSet ();

Myda. Fill (ds, "guestbook ");

DataGrid1.DataSource = ds. Tables ["guestbook"]. DefaultView;

DataGrid1.DataBind ();

}

Override protected void OnInit (EventArgs e)

{

Base. OnInit (e );

}
