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;

            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()

            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");
        }
    }
