C# 给Word每一页设置不同文字水印

Word中设置水印时，可使用预设的文字或自定义文字设置为水印效果，但通常添加水印效果时，会对所有页面都设置成统一效果，如果需要对每一页或者某个页面设置不同的水印效果，则可以参考本文中的方法。下面，将以C\# 代码为例，对Word每一页设置不同的文字水印效果作详细介绍。

--------------------

## 方法思路 ##

在给Word每一页添加文字水印前，首先需要在Word文档**每一页**正文的最后一个字符后面**插入“连续”分节符**，然后在**每一节的页眉段落里添加艺术字形状**，并设置形状大小、对齐方式等。最后保存文档。

## dll引用 ##

**方法1**

在程序中引入Spire.Doc.dll文件；将[Spire.Doc for .NET][]下载到本地，解压，找到BIN文件夹下的Spire.Doc.dll。然后在Visual Studio中打开“解决方案资源管理器”，鼠标右键点击“引用”，“添加引用”，将本地路径BIN文件夹下的dll文件添加引用至程序。

**方法2**

通过[NuGet][]安装。可通过以下2种方法安装：

1.可以在Visual Studio中打开“解决方案资源管理器”，鼠标右键点击“引用”，“管理NuGet包”，然后搜索“Spire.Doc”，点击“安装”。等待程序安装完成。

2.将以下内容复制到PM控制台安装。

Install-Package Spire.Doc -Version 10.1.14

## 代码示例 ##

给每页添加文字水印时，可参考如下步骤：

*  创建**Document**类的对象，并通过**LoadFromFile(string fileName)**方法加载Word文档。
 *  通过**Document.Sections\[\]**属性获取指定节。
 *  通过**HeadersFooters.Header**属性获取页眉，**HeaderFooter.AddParagraph()**方法添加段落到页眉。
 *  创建**ShapeObject**类的对象，并传入参数设置形状类型为**TextPlainText**类型的艺术字。并调用方法设置艺术字样式，如艺术字高度、宽度、旋转、颜色、对齐方式等。
 *  使用**DocumentObjectCollection.Add(IDocumentObject)**方法将艺术字添加到段落。
 *  最后，通过**Document.SaveToFile(string fileName, FileFormat fileFormat)**方法保存文档。

不同页面中设置不一样的文字水印效果，只需要获取该页面对应的节，然后参考上述用到的方法来添加即可。
