代码实现GirdView控件显示数据库数据出错,请大家帮忙看看
提示错误:数据源的类型无效。它必须是 IListSource、IEnumerable 或 IDataSource。 

后台文件:
using System;
using System.Collections;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
using MySql.Data.MySqlClient;
public partial class _Default : System.Web.UI.Page
{
  protected void Page_Load(object sender, EventArgs e)
  {
  if (!IsPostBack)
  {
  bind();
  }
  }
  public void bind()
  {
  string sql = string.Format("select * from UserInfo");
  MySqlConnection conn = new MySqlConnection("server=192.168.0.254;user id=root;password=110120110;database=dlxj;charset=gb2312");
  conn.Open();
  MySqlDataAdapter myda = new MySqlDataAdapter(sql, conn);
  DataSet myds = new DataSet();
  myda.Fill(myds);
  GridView1.DataSource = myda;
  //GridView1.DataKeyNames = new string[] { "Id" };
  GridView1.DataBind();
  conn.Close();
  }
}
页面文件:

新手练习,请大家帮帮忙
直接配置数据源已经可以正常显示了,就是代码实现出了问题

------解决方案--------------------
GridView1.DataSource = myds;
