关于asp.net 调用word模板，修改并导出

（在app_code中的公用方法）

1.添加引用Microsoft.Office.Interop.Word.dll

2.代码如下

   （1）引用：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 Word = Microsoft.Office.Interop.Word;
using System.Collections.Generic;
using System.IO;

（2）代码

public string ExpWordByWord(){

        Word._Application app = new Word.ApplicationClass();

        //表示System.Type信息中的缺少值
        object nothing = Type.Missing;
        try
        {
            object temp;

            temp = System.Web.HttpContext.Current.Server.MapPath("~/report/template/temp.doc");//读取模板文件

            //建立一个基于摸版的文档
            Word._Document doc = app.Documents.Add(ref temp, ref nothing, ref nothing, ref nothing);

           //得到第一个表格

           Word.Table tbl = doc.Tables[1];

            //模板表格的行数若不够是添加
            if (tbl.Rows.Count < 20)
            {
                for (int i = 1; i < 20 - tbl.Rows.Count; i++)
                    tbl.Rows.Add(ref nothing);
            }

          //在指定单元格填值
           tbl.Cell(1, 1).Range.Text = "单元格的值";                       

            object fileName = "";
                //保存到服务器（这里使用guid，或使用时间加随机数）

                Guid guid = Guid.NewGuid();
                fileName = System.Web.HttpContext.Current.Server.MapPath("~/temp/") + guid.ToString() + ".doc";//获取服务器路径

               //保存doc文档
                doc.SaveAs(ref fileName, ref nothing, ref nothing, ref nothing, ref nothing, ref nothing,
                ref nothing, ref nothing, ref nothing, ref nothing, ref nothing, ref nothing, ref nothing,
                ref nothing, ref nothing, ref nothing);
               
                doc.Close(ref nothing, ref nothing, ref nothing);
                app.Quit(ref nothing, ref nothing, ref nothing);

                ExtWord(fileName.ToString(), "test.doc");//输出word
            }
            else
            {
                resultMsg = "没有数据";
            }
        }
        catch(Exception ex)
        {
            resultMsg = "导出错误："+ex.Message;
            app.Quit(ref nothing, ref nothing, ref nothing);
        }

 

}

/// <summary>
    /// 输出word
    /// </summary>
    /// <param name="filename"></param>
    public void ExtWord(string fileName,string wordname)
    {
        //输出word
        System.IO.FileInfo file = new System.IO.FileInfo(fileName);
        System.Web.HttpContext.Current.Response.Clear();
        System.Web.HttpContext.Current.Response.Charset = "GB2312";
        System.Web.HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.UTF8;
        // 添加头信息，为"文件下载/另存为"对话框指定默认文件名
        System.Web.HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment; filename=" + HttpUtility.UrlEncode(wordname, System.Text.Encoding.UTF8));
        // 添加头信息，指定文件大小，让浏览器能够显示下载进度
        System.Web.HttpContext.Current.Response.AddHeader("Content-Length", file.Length.ToString());

        // 指定返回的是一个不能被客户端读取的流，必须被下载
        System.Web.HttpContext.Current.Response.ContentType = "application/ms-word";

        // 把文件流发送到客户端
        System.Web.HttpContext.Current.Response.WriteFile(file.FullName);
        // 停止页面的执行
        //HttpContext.Current.ApplicationInstance.CompleteRequest
        System.Web.HttpContext.Current.ApplicationInstance.CompleteRequest();
    }
