1. 服务端输出方式

1.1 html 输出方式最常用方式

优点：不需要任何插件

缺点：不是真正excel文件，做不了太复杂的格式，偶尔会出现打不开的情况

代码示例：

            Response.Clear();            Response.Buffer = true;            Response.Charset = "GB2312";            //设置了类型为中文防止乱码的出现            string danwei = Session["danWeiMingCheng"].ToString();            //2011.07.14 luochengxin            Response.AddHeader("Content-Disposition", "inline;filename=手术登记查询.xls", System.Text.Encoding.UTF8));            Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");            //设置输出流为简体中文            Response.ContentType = "application/ms-excel";            //设置输出文件类型为excel文件。            System.Globalization.CultureInfo myCItrad = new System.Globalization.CultureInfo("ZH-CN", true);            System.IO.StringWriter oStringWriter = new System.IO.StringWriter(myCItrad);            System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);            Response.Write(Sbr.ToString());            Response.Write("<meta http-equiv=Content-Type content=text/html;charset=gb2312>");            Response.Write(oStringWriter.ToString());            Response.End();

1.2 office com组件 输出方式

优点：生成真正的Excel文件，强类型编码

缺点：服务器需要安装office且与版本绑定太深（不推荐使用），常用cs类型程序开发

代码示例：

protected void Page_Load(object sender, EventArgs e)        {            if (!Page.IsPostBack)            {                ApplicationClass app = new ApplicationClass();                Workbook workBook = app.Workbooks.Open(@"e:\tt.xls", Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);                Worksheet sheet = (Worksheet)workBook.Worksheets[1];                Response.Write(sheet.Name + "<br/>");                Range range = sheet.get_Range("E7:J112", Type.Missing);                Range item = null;                for (int row = 0; row < range.Rows.Count; row++)                {                    for (int col = 0; col < range.Columns.Count; col++)                    {                        item = (Range)range.get_Item(row, col);                        Response.Write(item.Value2);                        Response.Write(" | ");                    }                    Response.Write("<br/>");                }                //关闭                app.Workbooks.Close();                app.Quit();                //释放                System.Runtime.InteropServices.Marshal.ReleaseComObject(item);                System.Runtime.InteropServices.Marshal.ReleaseComObject(range);                System.Runtime.InteropServices.Marshal.ReleaseComObject(sheet);                System.Runtime.InteropServices.Marshal.ReleaseComObject(workBook);                System.Runtime.InteropServices.Marshal.ReleaseComObject(app);                item = null;                app = null;                workBook = null;                range = null;                GC.Collect();                //杀进程                try{                KillExcelProcess();                }catch{}            }        }        public void KillExcelProcess()        {            Process[] myProcesses;            myProcesses = Process.GetProcessesByName("Excel");            foreach (Process myProcess in myProcesses)            {                myProcess.Kill();            }        }

1.3 NPOI 输出方式

优点：生成真正的Excel文件，可做特殊复杂操作，且为独立第三方DLL，不需要依然office组件解决了1.2的问题，

缺点：生成时占用内存资源大，CPU耗时大，如果生成一万条以上excel极其容易出现内存溢出

代码示例：

            private void button1_Click(object sender, EventArgs e)            {            	//创建工作薄            	HSSFWorkbook wk = new HSSFWorkbook();            	//创建一个名称为mySheet的表            	ISheet tb = wk.CreateSheet("mySheet");             	//创建一行，此行为第二行            	IRow row = tb.CreateRow(1);            	for (int i = 0; i < 20; i++)                	{            		ICell cell = row.CreateCell(i);  //在第二行中创建单元格            		cell.SetCellValue(i);//循环往第二行的单元格中添加数据            	}            	//打开一个xls文件，如果没有则自行创建，如果存在myxls.xls文件则在创建是不要打开该文件！            	using (FileStream fs = File.OpenWrite(@"c:/myxls.xls"))             	{            		wk.Write(fs);   //向打开的这个xls文件中写入mySheet表并保存。            		MessageBox.Show("提示：创建成功！");            	}            }

2. 客户端输出方式

2.1 OCX组件导出

优点：生成真正的Excel文件

缺点：仅IE下可用，需要开启activeX权限

代码示例：

       function AllAreaExcel(content) {            var oXL = new ActiveXObject("Excel.Application");            var oWB = oXL.Workbooks.Add();            var oSheet = oWB.ActiveSheet;            var div_all = content;            var sel = document.body.createTextRange();            sel.moveToElementText(div_all);            sel.select();            sel.execCommand("Copy");            oSheet.Paste();            oXL.Visible = true;        }

2.2 第三方JS插件

优点：

缺点：仅标准H5可用，IE兼容模式下不可能用
