asp.net(C#)套用模板操作Excel

  当需要输出带大量公式的Excel文档的时候,在代码里写公式就太累了。

  用设计好的Excel模板,复制一下,往里面添加数据比较省事。

  模板

  导出文件:

  using System;

  using System.Data;

  using System.Configuration;

  using System.Web;

  using System.Web.Security;

  using System.Web.UI;

  using System.Web.UI.WebControls;

  using System.Web.UI.WebControls.WebParts;

  using System.Web.UI.HtmlControls;

  using System.IO;

  using System.Reflection;

  using Microsoft.Office.Interop.Excel;

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

  {

  protected void Page_Load(object sender, EventArgs e)

  {

  if (!IsPostBack)

  Bind();

  }

  private void Bind()

  {

  //模板文件

  string TempletFileName = Server.MapPath("template/") + "template.xlsx";

  //导出文件

  string ReportFileName = Server.MapPath("xls/") + "out.xlsx";

  string strTempletFile = Path.GetFileName(TempletFileName);

  //将模板文件复制到输出文件

  FileInfo mode = new FileInfo(TempletFileName);

  mode.CopyTo(ReportFileName, true);

  //打开excel

  object missing = Missing.Value;

  Application app = null;

  Workbook wb = null;

  Worksheet ws = null;

  Range r = null;

  //

  app = new Microsoft.Office.Interop.Excel.Application();

  wb = app.Workbooks.Open(ReportFileName, false, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing);

  app.Visible = true;

  //得到WorkSheet对象

  ws = (Worksheet)wb.Worksheets.get_Item(1);

  //添加或修改WorkSheet里的数据

  ws.Cells[1, 1] = "100";

  ws.Cells[2, 1] = "100";

  ws.Cells[2, 2] = "100";

  //代码里写个公式

  r = (Range)ws.Cells[2, 3];

  r.Formula = "=A2*B2";

  //输出Excel文件并退出

  wb.Save();

  wb.Close(null, null, null);

  app.Workbooks.Close();

  app.Application.Quit();

  app.Quit();

  System.Runtime.InteropServices.Marshal.ReleaseComObject(ws);

  System.Runtime.InteropServices.Marshal.ReleaseComObject(wb);

  System.Runtime.InteropServices.Marshal.ReleaseComObject(app);

  ws = null;

  wb = null;

  app = null;

  }

  }
