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");
}
}
}

 '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

 '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")

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;

 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");

 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

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");
}
}
