C# 给Word不同页面设置不同背景

迈不过友情╰ 2022-10-26 14:18 198阅读 0赞

给Word文档设置背景时，通常只能针对整篇文档设置统一的背景，如果需要对某些页面单独设置背景，则需要通过另外的方式来实现。本文通过C\# 程序代码演示如何来实现。并附VB.NET代码作参考。

**思路**：通过在页眉中添加形状或者图片，并将形状或图片平铺（即设置形状或图片大小为页面大小）到整个页面。添加背景时，通过添加形状并设置形状颜色来设置成纯色背景效果；通过添加图片来实现图片背景效果。

**本次程序运行环境中包括**：引入[Spire.Doc.dll][]；.Net Framework 4.5.1

设置不同背景时，分以下2种情况：

## **1.** **只需设置首页背景和其他页面不同** ##

### 1.1 设置纯色背景 ###

## **2.** **设置指定多个页面背景不同** ##

**注：**给多个页面设置不同背景时，需要通过获取不同节的页眉来设置，本次程序环境中所用源文档已设置了多个节，如需手动设置分节，可参考代码：

document.Sections\[0\].Paragraphs\[0\].InsertSectionBreak(SectionBreakType.NoBreak);

### **2.1** **设置纯色背景** ###
