求助一个录入问题~

public partial class admin_product : System.Web.UI.Page

    protected void Page_Load(object sender, EventArgs e)
    {

    }
    protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)

        DropDownList2.SelectedIndex = id;
    }
    protected void Button1_Click1(object sender, EventArgs e)
    {
        if (this.FileUpload1.HasFile)//检查是否有文件
        {
            string fullFileName = this.FileUpload1.PostedFile.FileName;                     //文件路径名
            string fileName = fullFileName.Substring(fullFileName.LastIndexOf("\\") + 1);   //图片名称
            string type = fullFileName.Substring(fullFileName.LastIndexOf(".") + 1);        //图片格式

            if (type == "jpg" || type == "JPG" || type == "gif" || type == "GIF" || type == "BMP" || type == "bmp") //判断是否为图片类型
            {

        string pic = "";
        if(FileUpload1.PostedFile!=null)
        {
            pic=FileUpload1.PostedFile.FileName;
        }
        cmd.Parameters.Add(new SqlParameter("@pic", pic));

        cmd.Parameters.Add(new SqlParameter("@typeid", typeid));
        cmd.Parameters.Add(new SqlParameter("@note", note));
        cmd.Parameters.Add(new SqlParameter("@ntypeid", ntypeid));
        cmd.Connection = con;
        con.Open();
        SqlDataReader sdr = cmd.EndExecuteReader();
        this.content.ContentPlaceHolder1 = sdr;
        this.content.DataBind();
        con.Close();
    }
}
现在报错的是CS1501: “EndExecuteReader”方法没有采用“0”个参数的重载
我该怎么办？还有请高手说下我现在的pic是否录入的是fileupload1的图片路径，还是应该写成
cmd.Parametera.Add(new SqlParameter("@pic",path + fileName)),如果这样写可以，那么前面又做什么修改呢，请高手赐教 --------------------编程问答-------------------- “EndExecuteReader”方法没有采用“0”个参数的重载

ps：看下这个方法是如何使用的 --------------------编程问答-------------------- 现在报错的是CS1501: “EndExecuteReader”方法没有采用“0”个参数的重载

这个错误是不是说明需要参数啊，

cmd.EndExecuteReader(); 看看 cmd应该有其他方法执行 sqldataread赋值对象吧 --------------------编程问答-------------------- 已经修改SqlDataReader sdr = cmd.ExecuteReader();
新问题this.content.ContentPlaceHolder1 = sdr;
this.content.DataBind();
CS1061: “admin_product”不包含“content”的定义，并且找不到可接受类型为“admin_product”的第一个参数的扩展方法“content”(是否缺少 using 指令或程序集引用?)

我页面是在<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" runat="Server">容器内的

运行的时候出现这个错误 CS1061: “上传图片”不包含“Image1”的定义,并且找不到可接受类型为“上传图片  是怎么回事 --------------------编程问答-------------------- EndExecuteReader
改为
ExecuteReader

补充：.NET技术 ,  ASP.NET
