C# 给Word不同页面设置不同背景
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
【C#】
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);
System.Diagnostics.Process.Start("ColorBackground1.docx");
}
}
}

1.2 设置图片背景
【C#】
using Spire.Doc;
using Spire.Doc.Documents;
using Spire.Doc.Fields; 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; 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 //获取页面宽度、高度
float width = section.PageSetup.PageSize.Width;
float height = section.PageSetup.PageSize.Height; //添加图片到首页页眉
DocPicture pic0 = firstpara.AppendPicture("1.png");
pic0.TextWrappingStyle = TextWrappingStyle.Behind;
pic0.HorizontalAlignment = ShapeHorizontalAlignment.Center;
pic0.VerticalOrigin = VerticalOrigin.TopMarginArea;
pic0.Width = width;
pic0.Height = height; //在其他页面的页眉中添加图片
HeaderFooter otherheader = section.HeadersFooters.Header;
otherheader.Paragraphs.Clear();
Paragraph otherpara = otherheader.AddParagraph();
DocPicture pic1 = otherpara.AppendPicture("2.png");
pic1.TextWrappingStyle = TextWrappingStyle.Behind;

}
}

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

using Spire.Doc;
using Spire.Doc.Documents;
using Spire.Doc.Fields;
using System.Drawing; namespace DifferentBackground2
{
class Program
{
static void Main(string[] args)
{
//加载Word文档
Document doc = new Document();
doc.LoadFromFile("测试.docx"); //获取第一节
Section section1 = doc.Sections[0]; //获取页面宽度、高度
float width = section1.PageSetup.PageSize.Width;
float height = section1.PageSetup.PageSize.Height; //添加图片到页眉
HeaderFooter header1 = section1.HeadersFooters.Header;
header1.Paragraphs.Clear();
Paragraph para1 = header1.AddParagraph();
ShapeObject shape1 = para1.AppendShape(width, height, ShapeType.Rectangle);//添加形状
shape1.BehindText = true;//设置形状衬于文字下方
shape1.HorizontalAlignment = ShapeHorizontalAlignment.Center;//设置对齐方式，铺满页面
shape1.VerticalOrigin = VerticalOrigin.TopMarginArea;
shape1.FillColor = Color.LightSalmon;//形状颜色 //同理设置第二节页眉中的图片
Section section2 = doc.Sections[1];
HeaderFooter header2 = section2.HeadersFooters.Header;
header2.Paragraphs.Clear();
Paragraph para2 = header2.AddParagraph();
ShapeObject shape2 = para2.AppendShape(width, height, ShapeType.Rectangle);//添加形状
shape2.BehindText = true;//设置形状衬于文字下方
shape2.HorizontalAlignment = ShapeHorizontalAlignment.Center;//设置对齐方式，铺满页面
shape2.VerticalOrigin = VerticalOrigin.TopMarginArea;
shape2.FillColor = Color.Moccasin;//形状颜色 //同理设置第三节中的页眉中的图片
Section section3 = doc.Sections[2];
HeaderFooter header3 = section3.HeadersFooters.Header;
header3.Paragraphs.Clear();
Paragraph para3 = header3.AddParagraph();
ShapeObject shape3 = para3.AppendShape(width, height, ShapeType.Rectangle);//添加形状
shape3.BehindText = true;//设置形状衬于文字下方
shape3.HorizontalAlignment = ShapeHorizontalAlignment.Center;//设置对齐方式，铺满页面
shape3.VerticalOrigin = VerticalOrigin.TopMarginArea;
shape3.FillColor = Color.LawnGreen;//形状颜色 //保存文档
doc.SaveToFile("ColorBackground2.docx", FileFormat.Docx2013);
System.Diagnostics.Process.Start("ColorBackground2.docx");
}
}
