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");
 }
 }
}

【VB.NET】

Imports Spire.Doc
Imports Spire.Doc.Documents
Imports Spire.Doc.Fields
Imports System.Drawing

Namespace DifferentBackground1
 Class Program
 Private Shared Sub Main(args As String())
  '加载Word测试文档
  Dim doc As New Document()
  doc.LoadFromFile("测试.docx")

  '获取第一节
  Dim section As 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
  Dim firstpageheader As HeaderFooter = 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）
  Dim firstpara As Paragraph = firstpageheader.AddParagraph()
  '重新添加段落
  Dim width As Single = section.PageSetup.PageSize.Width
  '获取页面宽度、高度
  Dim height As Single = section.PageSetup.PageSize.Height
  Dim shape As ShapeObject = 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
  Dim otherheader As HeaderFooter = section.HeadersFooters.Header
  otherheader.Paragraphs.Clear()
  Dim otherpara As Paragraph = otherheader.AddParagraph()
  Dim shape1 As ShapeObject = 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")
 End Sub
 End Class
End Namespace

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;
  pic1.HorizontalAlignment = ShapeHorizontalAlignment.Center;
  pic1.VerticalOrigin = VerticalOrigin.TopMarginArea;
  pic1.Width = width;
  pic1.Height = height;


  //保存文档
  doc.SaveToFile("ImageBackground1.docx", FileFormat.Docx2013);
  System.Diagnostics.Process.Start("ImageBackground1.docx");
 }
 }
}

【VB.NET】

Imports Spire.Doc
Imports Spire.Doc.Documents
Imports Spire.Doc.Fields

Namespace DifferentBackground1
 Class Program
 Private Shared Sub Main(args As String())
  '加载Word测试文档
  Dim doc As New Document()
  doc.LoadFromFile("测试.docx")

  '获取第一节
  Dim section As Section = doc.Sections(0)

  '设置首页页眉页脚不同
  section.PageSetup.DifferentFirstPageHeaderFooter = True

  Dim firstpageheader As HeaderFooter = 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）
  Dim firstpara As Paragraph = firstpageheader.AddParagraph()
  '重新添加段落
  '获取页面宽度、高度
  Dim width As Single = section.PageSetup.PageSize.Width
  Dim height As Single = section.PageSetup.PageSize.Height

  '添加图片到首页页眉
  Dim pic0 As DocPicture = 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
  Dim otherheader As HeaderFooter = section.HeadersFooters.Header
  otherheader.Paragraphs.Clear()
  Dim otherpara As Paragraph = otherheader.AddParagraph()
  Dim pic1 As DocPicture = otherpara.AppendPicture("2.png")
  pic1.TextWrappingStyle = TextWrappingStyle.Behind
  pic1.HorizontalAlignment = ShapeHorizontalAlignment.Center
  pic1.VerticalOrigin = VerticalOrigin.TopMarginArea
  pic1.Width = width
  pic1.Height = height


  '保存文档
  doc.SaveToFile("ImageBackground1.docx", FileFormat.Docx2013)
  System.Diagnostics.Process.Start("ImageBackground1.docx")
 End Sub
 End Class
End Namespace

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

【C#】

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形状
  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形状
  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");
 }
 }
}
