使用Aspose.Words進行郵件合并操作一般情況下只會從數據源生成一個文件(例如創建發票或信件)。

產生多個文檔需要進行多次郵件合并。如果需要將數據源中的所有數據都存在于一個單獨的文件中,需要做到以下幾點:

• 循環數據表中的所有行。
• 在郵件合并前載入(或復制)原始文檔。
• 執行郵件合并，保存文件。

你可以在每個郵件合并前從一個文件或流中加載模板文件,但通常情況下,更為快速的方法是只加載一次文檔，然后在每次郵件合并前從內存中復制。

要注意的是,執行郵件合并你應該有一個適當的模板文件。這個模板可以是一個Microsoft Word模板或一個普通的Microsoft Word文檔,但它需要在插入數據的地方包含MERGEFIELD字段。每個字段的名稱應和數據源中相應的字段相同。
