Aspx C# MySQL 连接字符串未使用 web.Config 连接

Question

I am not an expert by any means with C# and asp but I have managed to make it to the end of my site and deploy. Everything works fine locally including the MySQL connection. However when I plug in the connection string given by my host I get error messages. I have looked everywhere to find a solution and even contacted the host who was no help at all. I'm so frustrated and I know the best of the best are here. I'm sure there is a more than one issue with all my code. I was basic HTML and JS and SQL up until like 3 weeks ago. Than you everyone.

Web.Config file

<configuration>
   <connectionStrings>
 <add name="mySQLconn" connectionString="DRIVER={MySQL ODBC 5.1 Driver};server=skyhill.ipowermysql.com; user id=skyhillweb; password=******; database=skyhill; OPTION=3;"
     providerName="MySql.Data.MySqlClient" />
   </connectionStrings>
 <system.web>
   <customErrors mode="Off"/>
   <compilation debug="true"/>
   <authentication mode="None"/>
 </system.web>
 <system.webServer>
   <defaultDocument>
     <files>
       <add value="/pages/default.aspx"/>
     </files>
   </defaultDocument>
 </system.webServer>
</configuration>

Here is the page (just a test page) the path is pages/abc.aspx is you want to see the error.

<form id="form1" runat="server">
   <asp:GridView ID="gridAgent" runat="server" AutoGenerateColumns="True">
   </asp:GridView>
   <asp:TextBox ID="MessageBox" runat="server">
   </asp:TextBox>
</form>

and here is the C# behind the page

using System;
using System.Configuration;
using System.Collections.Generic;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using MySql.Data.Common;
using MySql.Data.MySqlClient;

namespace SkhillWebApp.pages
{
   public partial class abc : System.Web.UI.Page
   {

      protected void Page_Load(object sender, EventArgs e)
      {
         MySqlConnection conn = new MySqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["mySQLconn"].ConnectionString);
         string strSQL = "SELECT agentID, FirstName, LastName FROM agent";
         conn.Open();
         MySqlDataAdapter mydata = new MySqlDataAdapter(strSQL, conn);
         MySqlCommandBuilder cmd = new MySqlCommandBuilder(mydata);
         DataSet ds = new DataSet();

         mydata.Fill(ds);

         gridAgent.DataSource = ds;
         gridAgent.DataBind();
         conn.Close();
      }
   }
}

And this is the code provided by my host to connect to the MySQL database.

Start
<% 
Dim ConnectionString 
ConnectionString="DRIVER={MySQL ODBC 5.1 Driver}; SERVER=skyhill.ipowermysql.com; PORT=3306;" &_
"DATABASE=skyhill; USER=skyhillweb; PASSWORD=*password*; OPTION=3;"
%>
' End

Answer 1

It doesn't like the 'Driver' parameter of the connection string your host provided. Try this in your web.config, adapted from the mysql connector docs .

<add name="mySQLconn" connectionString="Server=skyhill.ipowermysql.com;Database=skyhill;Uid=skyhillweb;Pwd=yourpassword;" providerName="MySql.Data.MySqlClient"/> 

Answer 2

您可以将旧版本的 MySQL dll 用于 .Net，它解决了问题。
