　　　　　　　　　　　　　　　　　　　　　　.NET經過調用Office組件導出Word文檔sql

　　最近作項目須要實現一個客戶端下載word表格的功能，該功能是用戶點擊"下載表格"，服務端將該用戶的數據查詢出來並生成數據到Word模板中，再反饋給客戶端下載。數據庫

實現思路以下：windows

利用微軟提供的Office的組件來完成，在服務器端指定目錄放置一個word模板(該模板中須要替換的數據信息用書籤標記好)，當請求過來的時候，讀取模板信息並將書籤內容替換成從數據庫得到的信息在返回給客戶端下載便可，代碼以下：瀏覽器

#region 根據申請單ID號和模板生成word下載文件(書籤的形式)
    public void DownLoadWordOld(string id)
    {
        if (string.IsNullOrEmpty(id))
        {
            id = "0";
        }
        string sql = "SELECT ID,ProposerName,PhoneNo,ProposerAddress,HouseArea,HouseType,HouseNature,ApplyDate" +
                   " from BettingStationApply where ID=@id ";
        SqlParameter[] parm = new SqlParameter[] { new SqlParameter("@id", int.Parse(id)) };
        //根據ID號取得當前申請單的詳細信息
        DataTable dt = DBHelper.GetDataSet(sql, parm);
        if (dt.Rows.Count > 0)
        {
            DataRow dr = dt.Rows[0];

            //一、先建立一個建立word的Application
            Word.Application wordApp = new Word.ApplicationClass();
            //二、建立一個word文檔
            Word.Document docFile = null;
            try
            {
                wordApp.Visible = false;
                //模板對象
                object objTemplete = Server.MapPath(@"/BettingStation/templete.docx");
                object objTrue = true;
                object objFalse = false;
                object objDocType = Word.WdDocumentType.wdTypeDocument;
                //實例化word文檔(已經讀取到模板的word文檔)
                docFile = wordApp.Documents.Add(ref objTemplete, ref objFalse, ref objDocType, ref objTrue);

                //定義書籤變量
                object ProposerName = "ProposerName";
                object PhoneNo = "PhoneNo";
                object ProposerAddress = "ProposerAddress";
                object HouseArea = "HouseArea";
                object HouseType = "HouseType";
                object HouseNature = "HouseNature";
                object ApplyDate = "ApplyDate";
                //獲取全部的書籤
                Word.Bookmarks books = docFile.Bookmarks;
                //給書籤賦值
                if (books.Exists("ProposerName"))
                {
                    books.get_Item(ref ProposerName).Range.Text = dr["ProposerName"].ToString();
                }
                if (books.Exists("PhoneNo"))
                {
                    books.get_Item(ref PhoneNo).Range.Text = dr["PhoneNo"].ToString();
                }

調用offic組件須要添加Interop.Microsoft.Office.Interop.Word.dll的引用，我電腦上裝的Office2010，因此添加Microsoft Word 14.0 Object Library的引用安全

Word模板在服務器端生成好後，在利用Response方法將生成的word文檔發送給客戶端下載，代碼以下：

    /// </summary>

    /// <param name="wordname">下載的Word文件名</param>
    public void ExtWord(string fileFullName, string wordname)
    {
        //輸出word
        FileInfo file = new System.IO.FileInfo(fileFullName);
        HttpContext.Current.Response.Clear();
        HttpContext.Current.Response.Charset = "GB2312";
        HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.UTF8;
        // 添加頭信息，爲"文件下載/另存爲"對話框指定默認文件名 
        HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment; filename=" + HttpUtility.UrlEncode(wordname, System.Text.Encoding.UTF8));
        // 添加頭信息，指定文件大小，讓瀏覽器可以顯示下載進度 
        HttpContext.Current.Response.AddHeader("Content-Length", file.Length.ToString());
