1、创建Word

public class OpenXmlWordUtility
{/// <summary>/// 文件全路径/// </summary>public string FilePath { get; private set; }/// <summary>/// 处理文档/// </summary>public WordprocessingDocument ProcessingDocument { get; private set; }/// <summary>/// 文档/// </summary>public Document Document{get{return this.ProcessingDocument.MainDocumentPart.Document;}}/// <summary>/// 打开文档/// </summary>public void OpenDocument(){this.ProcessingDocument = WordprocessingDocument.Open(this.FilePath, true);this.TitleParagraphs = this.GetTitleParagraphs();}/// <summary>/// 创建Word文档/// </summary>public void CreateDocument(){this.ProcessingDocument = WordprocessingDocument.Create(this.FilePath, WordprocessingDocumentType.Document);MainDocumentPart mainDocumentPart = this.ProcessingDocument.AddMainDocumentPart();mainDocumentPart.Document = new Document(new Body());Body body = mainDocumentPart.Document.Body;SectionProperties sectionProperties = new SectionProperties();PageSize pageSize = new PageSize();PageMargin pageMargin = new PageMargin();DocumentFormat.OpenXml.Wordprocessing.Columns columns = new DocumentFormat.OpenXml.Wordprocessing.Columns() { Space = "220" }; //720  DocGrid docGrid = new DocGrid() { LinePitch = 100 }; //360  sectionProperties.Append(pageSize, pageMargin, columns, docGrid);body.Append(sectionProperties);mainDocumentPart.Document.Save();}/// <summary>/// 保存文档/// </summary>public void SaveDocument(){this.ProcessingDocument.MainDocumentPart.Document.Save();}/// <summary>/// 关闭文档/// </summary>public void CloseDocument(){if (this.ProcessingDocument != null){this.ProcessingDocument.Close();this.ProcessingDocument.Dispose();}}/// <summary>/// 清除指定标题下的所有内容/// </summary>public void ClearTitleContent(WordTitle title){var index = this.WordTitles.IndexOf(title);//title.Paragraph.NextSibling().RemoveAllChildren();//return;OpenXmlElement startElement = title.Paragraph.NextSibling();OpenXmlElement stopElement = null;if (index != this.WordTitles.Count - 1){var tempLt = this.WordTitles.Skip(index + 1);var tagTitle = tempLt.FirstOrDefault(p => p.Level == title.Level);if (tagTitle != null){stopElement = tagTitle.Paragraph;OpenXmlElement tempElement = startElement;List<OpenXmlElement> openxmleList = new List<OpenXmlElement>();while (tempElement != stopElement){openxmleList.Add(tempElement);tempElement = tempElement.NextSibling();}foreach (var openXmlElement in openxmleList){openXmlElement.Remove();}}else // 等于null 通常是最后一个章节{stopElement = null;OpenXmlElement tempElement = startElement;List<OpenXmlElement> openxmleList = new List<OpenXmlElement>();while (tempElement != stopElement){openxmleList.Add(tempElement);tempElement = tempElement.NextSibling();}foreach (var openXmlElement in openxmleList){openXmlElement.Remove();}}}}/// <summary>/// 创建纵向页分节符/// </summary>/// <returns></returns>public Paragraph CreatePortraitSectionBreakParagraph(){Paragraph paragraph1 = new Paragraph() { RsidParagraphAddition = "00052B73", RsidRunAdditionDefault = "00052B73" };ParagraphProperties paragraphProperties1 = new ParagraphProperties();SectionProperties sectionProperties1 = new SectionProperties() { RsidR = "00052B73" };//  PageSize pageSize1 = new PageSize() { Width = (UInt32Value)16838U, Height = (UInt32Value)11906U, Orient = PageOrientationValues.Landscape };PageSize pageSize1 = new PageSize();//PageMargin pageMargin1 = new PageMargin() { Top = 1440, Right = (UInt32Value)1800U, Bottom = 1440, Left = (UInt32Value)1800U, Header = (UInt32Value)851U, Footer = (UInt32Value)992U, Gutter = (UInt32Value)0U };DocumentFormat.OpenXml.Wordprocessing.Columns columns1 = new DocumentFormat.OpenXml.Wordprocessing.Columns() { Space = "425" };DocGrid docGrid1 = new DocGrid() { Type = DocGridValues.Lines, LinePitch = 312 };sectionProperties1.Append(pageSize1);//  sectionProperties1.Append(pageMargin1);sectionProperties1.Append(columns1);sectionProperties1.Append(docGrid1);paragraphProperties1.Append(sectionProperties1);paragraph1.Append(paragraphProperties1);return paragraph1;}/// <summary>/// 获取新段落/// </summary>/// <param name="text">段落文本</param>/// <returns>段落</returns>public Paragraph CreateParagraph(string text){Paragraph paragraph = new Paragraph();Run run = new Run();run.Append(new Text(text));paragraph.Append(run);return paragraph;}
}

2、新增标题并居中显示

 OpenXmlWordUtility wordUtility = new OpenXmlWordUtility();DocumentFormat.OpenXml.Wordprocessing.Paragraph par = this.WordUtility.CreateParagraph("1");  //新建标题1par.PrependChild(new DocumentFormat.OpenXml.Wordprocessing.ParagraphProperties());DocumentFormat.OpenXml.Wordprocessing.ParagraphProperties pPr2 = par.ParagraphProperties;// 设置StyleId  if (pPr2.ParagraphStyleId == null)pPr2.ParagraphStyleId = new DocumentFormat.OpenXml.Wordprocessing.ParagraphStyleId();pPr2.ParagraphStyleId.Val = "1";if (pPr2.Justification== null)pPr2.Justification= new DocumentFormat.OpenXml.Wordprocessing.Justification(){ Vall = DocumentFormat.OpenXml.Wordprocessing.JustificationValues.Center};this.WordUtility.Document.Body.Append(par);StyleDefinitionsPart styleDefinitionsPart1 = this.WordUtility.Document.MainDocumentPart.AddNewPart<StyleDefinitionsPart>("rId1");GeneratedCode.GeneratedClass.GenerateStyleDefinitionsPart1Content(styleDefinitionsPart1);this.WordUtility.SaveDocument();this.WordUtility.CloseDocument();
