背景：C#web程序。
需求：程序的某個表單需要打印出來，又不能直接打印網頁，因此需要後臺先生成word文件。
準備：
1.做一個word模板，要生成的樣式，在要填寫數據的位置加上書籤（word內實現）
2.引用word的服務引用office.dll、Microsoft.Office.Interop.Word.dll、Microsoft.Vbe.Interop.dll
3.程序的web.config的<system.web>中添加<identity impersonate="true" userName="***" password="**" />計算機賬號和密碼，這個是爲了發佈後別人可以調用，否則只能本機使用了。
程序邏輯：
1.複製生成一個新的word文件。
2.把數據填寫到新的word文件內。
3.當有子表的時候（如下圖1），獲取第四行的對象，然後添加的word內，然後再原來的行填寫數據，循環執行，最後刪掉最後一行
4.保存新的word文件，然後將新的word文件的地址返回給用戶，用戶直接下載。
圖一：模板表單
圖二：生成的打印表單
代碼（只填寫數據部分）：
// entity 需要填寫的對象，因爲改對象不完整，所以需要關聯其他對象才能完整填寫public ActionResult ExecuteExportWord(InvoiceEntity entity)
