怎么用ExcelHelper实现如下功能
HTML code


<body>
    <form id="form1" runat="server">
    <div>
    <INPUT id="File1" type="file" name="File1" runat="server"/>
    <asp:Button id="Button1" runat="server" Text="上传表1" OnClick="Button1_Click"></asp:Button>
      <asp:Button id="Button2" runat="server" Text="保存" OnClick="Button2_Click"></asp:Button>
      
      
     
      </div>
      
      
       
      <div>
    
        <asp:GridView ID="GridView1" runat="server" CellPadding="3"  BackColor="White" BorderColor="#CCCCCC"  BorderWidth="1px" Font-Size="12px" >
              <RowStyle ForeColor="#000066" />
<SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" CssClass="ms-formlabel DataGridFixedHeader"/>
<HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" />

        </asp:GridView>
    </div>
    
          
    </form>
</body>





C# code

 protected void Button1_Click(object sender, EventArgs e)
    {
        string strPath = Request.PhysicalApplicationPath + "\\upfile\\" + DateTime.Now.ToString("yyyyMMddhhmmss") + ".xls";
    

        File1.PostedFile.SaveAs(strPath);
      
   

        string mystring = "Provider = Microsoft.Jet.OLEDB.4.0 ; Data Source = '" +  strPath + "';Extended Properties=Excel 8.0";

        OleDbConnection cnnxls = new OleDbConnection(mystring);

        OleDbDataAdapter myDa = new OleDbDataAdapter("select * from [Sheet1$]", cnnxls);

        DataSet myDs = new DataSet();

        myDa.Fill(myDs);
        GridView1.DataSource = myDs.Tables[0];
        GridView1.DataBind();



    }




实现的简单的上传excle后绑定在gridview

但因使用的电脑中的excle文件如果没叫管理员解锁是传不了,如果用ExcelHelper应该不用解锁就能上传
要怎么加上应用ExcelHelper呢?

------解决方案--------------------
如果说可以读取的话,将excel中的数据读出来绑定到DataTable中
然后再与GridView绑定
C# code

 DataTable table = new DataTable();
            StreamReader reader = new StreamReader(path + fileName, Encoding.GetEncoding("GB2312"));
            string columnName = reader.ReadLine();
            string[] columns = columnName.Split('\t');
            string strBody = reader.ReadToEnd();
            //关闭流并释放资源
            reader.Close();
            reader.Dispose();
             File.Delete(path + fileName);//删除临时文件信息
            strBody = strBody.Replace("\r\n", "あ");//看一下行与行之间是用什么分割的
            string[] rows = strBody.Split('あ');
            int rowsCount = rows.Length;
            //向DataTable中添加DataColumn
            DataColumn column = new DataColumn("proName");
            table.Columns.Add(column);
            DataColumn column1 = new DataColumn("price");
            table.Columns.Add(column1);
            DataColumn column2 = new DataColumn("stock");
            table.Columns.Add(column2);
            DataColumn column3 = new DataColumn("pic");
            table.Columns.Add(column3);
            DataColumn column4 = new DataColumn("descript");
            table.Columns.Add(column4);
            for (int i = 0; i < rows.Length; i++)
            {
