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>
