C#.NET连接mysql方法

 mysql.data.dll拷贝到bin下面并引用一下
using MySql.Data.MySqlClient;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
string myConnectionString = "Database=test;Data Source=localhost;User Id=root;Password=admin";
MySqlConnection mycn = new MySqlConnection(myConnectionString);

try
{
mycn.Open();
Response.Write("<mce:script type="text/javascript"><!--
alert('连接成功')
// --></mce:script>");
}
catch (Exception ex)
{
Response.Write("<mce:script type="text/javascript"><!--
alert(" ex.ToString() ")
// --></mce:script>");
}
}
}
也可以配置app.config (web.config):
<appSettings>
<add key="Con" value="Provider=MySQLProv;Data Source=test;User Id=root;Password=admin;pooling=false;CharSet=utf8;port=3306"/>
</appSettings>
