Spire.Doc for .NET支持给Word文档设置背景，可设置单一颜色、渐变颜色以及图片背景。设置背景时，常见的方法是为整篇文章设置统一的背景，即每个页面的背景都是一样的，如这篇文章中的方法。本文，将介绍如何来给Word中的不同页面设置不同背景。具体分以下情况来设置。
1、只需设置首页背景和其他页面不同
1.1 设置纯色背景
using Spire.Doc;
using Spire.Doc.Documents;
using Spire.Doc.Fields;
using System.Drawing;
namespace DifferentBackground1
{
class Program
{
static void Main(string[] args)
{
//加载Word测试文档
Document doc = new Document();
doc.LoadFromFile("测试.docx");
//获取第一节
Section section = doc.Sections[0];
//设置首页页眉页脚不同
section.PageSetup.DifferentFirstPageHeaderFooter = true;
//在首页页眉添加形状
HeaderFooter firstpageheader = section.HeadersFooters.FirstPageFooter;//获取首页页眉
firstpageheader.Paragraphs.Clear();//清除页眉默认的段落格式（因默认页眉格式中包含有一条横线）
Paragraph firstpara = firstpageheader.AddParagraph();//重新添加段落
float width = section.PageSetup.PageSize.Width;//获取页面宽度、高度
float height = section.PageSetup.PageSize.Height;
ShapeObject shape = firstpara.AppendShape(width, height, ShapeType.Rectangle);//添加形状
shape.BehindText = true;//设置形状衬于文字下方
shape.HorizontalAlignment = ShapeHorizontalAlignment.Center;//设置对齐方式，铺满页面
shape.VerticalOrigin = VerticalOrigin.TopMarginArea;
shape.FillColor = Color.LightBlue;//形状颜色
//在其他页面的页眉中添加形状
HeaderFooter otherheader = section.HeadersFooters.Header;
otherheader.Paragraphs.Clear();
Paragraph otherpara = otherheader.AddParagraph();
ShapeObject shape1 = otherpara.AppendShape(width, height, ShapeType.Rectangle);
shape1.BehindText = true;
shape1.HorizontalAlignment = ShapeHorizontalAlignment.Center;
shape1.VerticalOrigin = VerticalOrigin.TopMarginArea;
shape1.FillColor = Color.Pink;
//保存文档
doc.SaveToFile("ColorBackground1.docx", FileFormat.Docx2013);

shape1.HorizontalAlignment = ShapeHorizontalAlignment.Center;//设置对齐方式，铺满页面
shape1.VerticalOrigin = VerticalOrigin.TopMarginArea;

shape2.HorizontalAlignment = ShapeHorizontalAlignment.Center;//设置对齐方式，铺满页面
shape2.VerticalOrigin = VerticalOrigin.TopMarginArea;
