Aspose.Words for .NET是一種高級Word文檔處理API，用于執行各種文檔管理和操作任務。API支持生成，修改，轉換，呈現和打印文檔，而無需在跨平臺應用程序中直接使用Microsoft Word。此外，API支持所有流行的Word處理文件格式，并允許將Word文檔導出或轉換為固定布局文件格式和最常用的圖像/多媒體格式。

>>Aspose.Words for .NET已經更新至v20.5，提供顯示/隱藏語法和拼寫錯誤的功能，引入了可在文檔內部使用水印的新幫助程序類，添加了為OOXML文檔設置壓縮級別的功能，點擊下載體驗

Aspose.Words具有用于生成自定義條形碼的界面，這使得使用Aspose.Words和Aspose.BarCode一起使用非常容易，以在輸出文檔中呈現條形碼圖像。例如，您可以將包含DISPLAYBARCODE字段的DOC，OOXML或RTF文檔加載到Aspose.Words中，提供自定義條形碼生成器的實現并保存為固定頁面格式，例如PDF，XPS等。典型的DISPLAYBARCODE字段具有以下語法：

{DISPLAYBARCODE“ SomeData” QR \ h 720}

下面是利用Aspose.BarCode API的示例代碼生成器。本示例說明如何使用Aspose.Words和Aspose.BarCode API在Word文檔中DISPLAYBARCODE字段的位置插入條形碼圖像。
