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、只需设置凯发线上登陆下载网址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];
//设置凯发线上登陆下载网址首页页眉页脚不同
section.pagesetup.differentfirstpageheaderfooter = true;
//在凯发线上登陆下载网址首页页眉添加形状
headerfooter firstpageheader = section.headersfooters.firstpagefooter;//获取凯发线上登陆下载网址首页页眉
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

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()

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];
//设置凯发线上登陆下载网址首页页眉页脚不同
section.pagesetup.differentfirstpageheaderfooter = true;
headerfooter firstpageheader = section.headersfooters.firstpagefooter;//获取凯发线上登陆下载网址首页页眉
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;
//添加图片到凯发线上登陆下载网址首页页眉
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");
}
}

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)
'设置凯发线上登陆下载网址首页页眉页脚不同
section.pagesetup.differentfirstpageheaderfooter = true
dim firstpageheader as headerfooter = section.headersfooters.firstpagefooter
'获取凯发线上登陆下载网址首页页眉

pic0.textwrappingstyle = textwrappingstyle.behind
pic0.horizontalalignment = shapehorizontalalignment.center
pic0.verticalorigin = verticalorigin.topmarginarea

pic0.height = height
'在其他页面的页眉中添加图片
dim otherheader as headerfooter = section.headersfooters.header

'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
注意：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，请参考这篇文章。
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");
