使用OpenXml给word文档添加文字，每个模块都有自己对于的属性以及内容，要设置样式就先声明属性对象，将样式Append到属性里面，再将属性append到模块里面，那么模块里面的内容就具备该样式了。此方法默认是在文件后面追加内容
Code：
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using DocumentFormat.OpenXml; using DocumentFormat.OpenXml.Packaging; using DocumentFormat.OpenXml.Wordprocessing; namespace AddStringToWord { public class Program { public static void Main(string[] args) { AddString("Test.docx", "你好呀"); } public static void AddString(string filePath, string str) { using (WordprocessingDocument doc = WordprocessingDocument.Open(filePath, true)) { Paragraph paragraph = new Paragraph(); Run run = new Run(); RunProperties runProperties = new RunProperties(); //属性 RunFonts fonts = new RunFonts() { EastAsia = "DFKai-SB" }; // 设置字体 FontSize size = new FontSize() { Val = "52" }; // 设置字体大小 Color color = new Color() { Val = "red" }; // 设置字体样式 // 将样式添加到属性里面 runProperties.Append(color); runProperties.Append(size); runProperties.Append(fonts); run.Append(runProperties); run.Append(new Text(str)); paragraph.Append(run); doc.MainDocumentPart.Document.Body.Append(paragraph); doc.MainDocumentPart.Document.Save(); } } } }
