C# 设置Word页面大小和页边距

using Spire.Doc;

using Spire.Doc.Documents;

namespace SetPageSize_Doc

{

class Program

{

static void Main(string[] args)

{

//实例化一个Document对象

Document doc = new Document();

//载入测试的Word文档

doc.LoadFromFile("test.docx");

//获取第一个Section对象

Section sec = doc.Sections[0];

//设置纸张大小为信纸

sec.PageSetup.PageSize = PageSize.Letter;

//分别设置四个方向的页边距

sec.PageSetup.Margins.Top = 20f;

sec.PageSetup.Margins.Left = 30f;

sec.PageSetup.Margins.Bottom = 20f;

sec.PageSetup.Margins.Right = 30f;

//把纸张方向设置为横向

sec.PageSetup.Orientation = PageOrientation.Landscape;

//保存并打开文档

doc.SaveToFile("result.docx", FileFormat.Docx2010);

System.Diagnostics.Process.Start("result.docx");
