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。
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
给每页添加文字水印时，可参考如下步骤：
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。
