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。
