问题复现

用Richeditcontrol编辑如下内容并保存为.docx文件:

用word或wps打开的效果:

寻找原因

我用word编辑个一样内容的文件,将这两个文件的扩展名修改为zip,解压后经过对比,发现document.xml文件这里不同:

我用bing搜索了这个关键字,搜索到了相关文档,奈何和谐社会。

解决办法

增加一个“保存“按钮,保存为docx文件后,把其中的document.xml文件修改之。代码如下:

using DevExpress.XtraRichEdit;
using Ionic.Zip;
using System;
using System.IO;
using System.Linq;
using System.Windows.Forms;
using System.Xml;

namespace RicheditcontrolFontDemo
{
    public partial class FormMain : Form
    {
        public FormMain()
        {
            InitializeComponent();
        }

        private void barButtonItemSave_ItemClick(object sender, DevExpress.XtraBars.ItemClickEventArgs e)
        {
            SaveFileDialog sfd = new SaveFileDialog
            {
                Filter = "doc|*.docx"
            };
            if (sfd.ShowDialog() == DialogResult.OK)
            {
                this.richEditControl.SaveDocument(sfd.FileName, DocumentFormat.OpenXml);
                MondifyFonts(sfd.FileName);
            }
        }

        private void MondifyFonts(string path)
        {
            using (ZipFile zip = new ZipFile(path)) // DotNetZip
            {
                var entry = zip.First(e => e.FileName == "word/document.xml");

                string tempPath = DateTime.Now.ToString("yyyyMMddHHmmssfff");
                entry.Extract(tempPath);
                AddEastAsiaFont($"{tempPath}//word/document.xml");
                zip.RemoveEntry(entry);
                zip.AddFile($"{tempPath}//word/document.xml", "word");
                zip.Save();

                Directory.Delete(tempPath, true);
            }
        }

        private void AddEastAsiaFont(string file)
        {
            XmlDocument doc = new XmlDocument();
            XmlNamespaceManager xmlm = new XmlNamespaceManager(doc.NameTable);
            xmlm.AddNamespace("w", "http://schemas.openxmlformats.org/wordprocessingml/2006/main");
            doc.Load(file);
            var nodes = doc.SelectNodes("//w:rFonts", xmlm);

            foreach (XmlNode node in nodes)
            {
                if (!AnyEastAsiaAttribute(node))
                {
                    string fontName = GetFontName(node);
                    if (fontName != null)
                    {
                        XmlAttribute atr = doc.CreateAttribute("w", "eastAsia", "http://schemas.openxmlformats.org/wordprocessingml/2006/main");
                        atr.Value = fontName;
                        node.Attributes.Append(atr);
                    }
                }
            }

            doc.Save(file);
        }

        private string GetFontName(XmlNode node)
        {
            foreach (XmlAttribute item in node.Attributes)
            {
                if (item.Name == "w:ascii" || item.Name == "w:hAnsi")
                {
                    return item.Value;
                }
            }
            return null;
        }

        private bool AnyEastAsiaAttribute(XmlNode node)
        {
            foreach (XmlAttribute item in node.Attributes)
            {
                if (item.Name == "w:eastAsia")
                {
                    return true;
                }
            }

            return false;
        }
    }
}
