    E-iceblue：C# 给Word不同页面设置不同背景

    作者：E-iceblue 时间：2021-02-02 16:23

    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");
        }
    }
}

    Class Program
        Private Shared Sub Main(args As String())

    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
    View Code

     

    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图片
            Section section2 = doc.Sections[
