使用第3方组件 Myxls 实现gridView 分页导出

使用第3方组件实现导出：

private void Method(GridView GridView1)
        {
            org.in2bits.MyXls.XlsDocument doc = new org.in2bits.MyXls.XlsDocument();
            doc.FileName = DateTime.Now.ToString().Replace("-", "").Replace(":", "").Replace(" ", "") + ".xls";//excel文件名称
            org.in2bits.MyXls.Worksheet sheet = doc.Workbook.Worksheets.AddNamed("sheet1");//Excel工作表名称
            org.in2bits.MyXls.Cells cells = sheet.Cells;
            int colnum = GridView1.Columns.Count; //获取gridview列数
            for (int i = 0; i < colnum; i++)
            {
                cells.Add(1, (i + 1), GridView1.Columns[i].HeaderText);//导出gridView列名
            }
            for (int i = 0; i < GridView1.Rows.Count; i++)
            {
                for (int j = 0; j < colnum; j++)
                {
                    if (j == 4)
                    {
                        string a = ((Label)GridView1.Rows[i].Cells[4].FindControl("Lbl1")).Text.ToString();
                        cells.Add((i + 2), 5, a);
                    }
                    else if (j == 5)
                    {
                        cells.Add((i + 2), 6, ((Label)GridView1.Rows[i].Cells[5].FindControl("label1")).Text).ToString();
                    }
                    else
                    {
                        cells.Add((i + 2), (j + 1), GridView1.Rows[i].Cells[j].Text.Trim());
                    }

                }

            }
            //doc.Save(@"D:\");  //保存到指定位置
            doc.Send();//把写好的excel文件输出到客户端
        }
