Word文件要轉成PDF要Office 2007版本以上才能實現

Step 1.在Server上已裝好Office Word 2007後到2007 Microsoft Office 增益集：Microsoft 另存 PDF 或 XPS 檔

下載安裝此外掛包

Step 2.安裝完後，對著Web Site專案右鍵>加入參考

在COM頁籤中，把「Microsoft Word 12.0 Object Library 」加入參考

另外也把.NET頁籤中的「Microsoft.Office.Interop.Word」版本12.0.0.0也加入參考

Step 3. 接下來開始寫程式，在.aspx設計畫面拉出兩個控制項


 <asp:FileUpload ID="fu_upload" runat="server" />
    <asp:Button ID="btn_execute" Text="請按我" runat="server" OnClick="btn_execute_Click" />

Step 4. Code-Behind

using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
/*要引用以下的命名空間*/
using Microsoft.Office.Interop.Word;
using System.IO;

    }

    ApplicationClass wordApplication = new ApplicationClass();
    Document wordDocument = null;
    object paramSourceDocPath = @"C:\Temp\Test.docx";//Sample Path
    object paramMissing = Type.Missing;

    //Button Click事件
    protected void btn_execute_Click(object sender, EventArgs e)
    {
        if (fu_upload.HasFile)//有選擇檔案的話，就做上傳檔案
        {
            string newFileName = Guid.NewGuid().ToString() + Path.GetExtension(fu_upload.FileName);
            fu_upload.SaveAs(Server.MapPath("~/upload/" + newFileName));//已把Word附檔上傳至Server


            //原始Word附檔在Server上的路徑
            this.paramSourceDocPath = Server.MapPath("~/upload/" + newFileName);

            WdExportFormat paramExportFormat = WdExportFormat.wdExportFormatPDF;//要匯出為PDF格式，也可以選擇wdExportFormatXPS要匯出為XPS
            bool paramOpenAfterExport = false;//轉換完後是否要開啟完成檔，這要選false，不然檔案開在Server端幹嘛？
            WdExportOptimizeFor paramExportOptimizeFor =

            {
                // Respond to the error
            }
            finally
            {
                // Close and release the Document object.
                if (wordDocument != null)
                {
                    wordDocument.Close(ref paramMissing, ref paramMissing,
                        ref paramMissing);
                    wordDocument = null;
                }

                // Quit Word and release the ApplicationClass object.
                if (wordApplication != null)
                {
                    wordApplication.Quit(ref paramMissing, ref paramMissing,
                        ref paramMissing);
                    wordApplication = null;
                }

                GC.Collect();
                GC.WaitForPendingFinalizers();
                GC.Collect();
                GC.WaitForPendingFinalizers();
            }


        }
    }


}

此程式碼可以轉*.doc和*.docx，轉換出來的效果：

有圖有超連結，效果不差~

懶人研究包
