用c#实现将DataGrid中的数据导为microsoft office excel 2003

要实现讲datagrid中的数据导为excel,必须引入microsoft的microsoft office webComponent(OWC),从vs.net中引入OWC后，就可以实现将datagrid导为excel.具体的方法如下：
以下是c#代码文件：
using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Data.SqlClient;
using System.Drawing;
using System.Web;
using System.Web.SessionState;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;

namespace TestExeclFromDataGrid
{
   /// <summary>
   /// WebForm1 的摘要说明。
   /// </summary>
   public class WebForm1 : System.Web.UI.Page
   {
      protected System.Data.SqlClient.SqlDataAdapter sqlDataAdapter1;
      protected System.Data.SqlClient.SqlCommand sqlSelectCommand1;
      protected System.Data.SqlClient.SqlConnection sqlConnection1;
      protected TestExeclFromDataGrid.dsProdcuts dsProdcuts1;
      protected System.Web.UI.WebControls.Button Button1;
      protected System.Web.UI.WebControls.Label Label1;
      protected System.Web.UI.WebControls.DataGrid DataGrid1;
   
      private void Page_Load(object sender, System.EventArgs e)
      {
         this.sqlDataAdapter1.Fill(this.dsProdcuts1);
         if(!Page.IsPostBack)
         {
            this.DataGrid1.DataBind();
         }// 在此处放置用户代码以初始化页面
      }
      
      public void DataGridToExcel()
      {
         string filesName=this.File1.Value;
         OWC.SpreadsheetClass XlsSheet = new OWC.SpreadsheetClass();//实例化execl中的一张表
         int tempColumn = 0;
         foreach(System.Web.UI.WebControls.DataGridColumn Oitem in this.DataGrid1.Columns)//遍历整个datagrid的每一列,添加表头
         {
XlsSheet.ActiveSheet.Cells[1,tempColumn+1]=Oitem.HeaderText;//添加表头
            tempColumn++;
         }
         for(int i=1;i <= this.DataGrid1.Items.Count;i++)//遍历datagrid中的每一行，
         {
            for(int j=1;j<=this.DataGrid1.Items[i-1].Cells.Count;j++)
            {
               XlsSheet.ActiveSheet.Cells[i+1,j]=this.DataGrid1.Items[i-1].Cells[j-1].Text;//给刚才定义好的excel表没格负值
            }
         }
         XlsSheet.ActiveSheet.Export(filesName,OWC.SheetExportActionEnum.ssExportActionNone);//execl表格的导出
      }

      #region Web Form Designer generated code
      override protected void OnInit(EventArgs e)
      {
         //
         // CODEGEN：该调用是 ASP.NET Web 窗体设计器所必需的。
         //
         InitializeComponent();
         base.OnInit(e);
      }
      
      /// <summary>
      /// 设计器支持所需的方法 - 不要使用代码编辑器修改
      /// 此方法的内容。
