                stringStream.Write(html);

            AltChunk altChunk = new AltChunk();
            altChunk.Id = altChunkId;

            mainPart.Document.Body

Finally, I found the third party dll which is available in Nuget package manager .最后，我在Nuget package manager中找到了第三方 dll 。 Here is the sample code solution.这是示例代码解决方案。 More Info: VISIT更多信息：访问

        string filename = @"C:\test.docx";
        Document document = new Document();
        document.LoadFromFile(filename);

        TextSelection[] selections1 = document.FindAllString("test2", true, true);
        //Here in first parameter you need pass the string which you want to replace.
        foreach (TextSelection selection1 in selections1)
        {
            TextRange range1 = selection1.GetAsOneRange();
            Paragraph paragraph = range1.OwnerParagraph;
            int index1 = paragraph.ChildObjects.IndexOf(range1);
            paragraph.AppendHTML("<b>Hello</b>");
            range1.OwnerParagraph.ChildObjects.Remove(range1);
        }
        document.SaveToFile(filename, FileFormat.Docx);

Import below namespaces.导入以下命名空间。
