大家帮我看看这个问题是怎么回事

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Data.SqlClient;
public partial class vote : System.Web.UI.Page


{
    private string voteID = "1";
    protected void Page_Load(object sender, EventArgs e)
    {
        //创建连接
        SqlConnection con = DB.createConnection();
        con.Open();
        //查询选举的标题
        SqlCommand cmd = new SqlCommand("select voteTitle from voteMaster where voteID=" + this.voteID, con);
        string title = Convert.ToString(cmd.ExecuteScalar());
        this.lblTitle.Text = title;
        //查询对应的选举投票项目
        SqlCommand cmdItem = new SqlCommand(" select voteDetailsID,voteItem from voteDetails shere voteID=" + this.voteID,con );
        SqlDataReader sdr = cmdItem.ExecuteReader();
        this.rBtnItems.DataSource = sdr;
        this.rBtnItems.DataTextField = "voteItem";
        this.rBtnItems.DataValueField="voteDetailsID";
        this.rBtnItems.DataBind();
        sdr.Close();
        //关闭连接
        con.Close();

    }
}

运行后产生错误（如下）：
