这里可能会遇到一个问题，由于转化为HTML文件的页面编码可能使得浏览器无法正确解读，所以需要转码，转换代码如下（不同word文档转换成html，格式编码会不同，这里统一改成GB2312编码）：
private void TransHTMLEncoding(string strFilePath){try{System.IO.StreamReader sr = new System.IO.StreamReader(strFilePath, Encoding.GetEncoding(0));string html = sr.ReadToEnd();sr.Close();//此处有两种写法//写法一（语句中包含有“<meta”都会被替换成gb2312，不太准确）html = System.Text.RegularExpressions.Regex.Replace(html, @"<meta[^>]*>", "<meta http-equiv=Content-Type content='text/html; charset=gb2312'>", System.Text.RegularExpressions.RegexOptions.IgnoreCase);//写法二（只修改编码格式一句）html = System.Text.RegularExpressions.Regex.Replace(html, @"<meta http-equiv=Content-Type[^>]*>", "<meta http-equiv=Content-Type content='text/html; charset=gb2312'>", System.Text.RegularExpressions.RegexOptions.IgnoreCase);System.IO.StreamWriter sw = new System.IO.StreamWriter(strFilePath, false, Encoding.Default);sw.Write(html);sw.Close();}catch (Exception ex){Page.RegisterStartupScript("alt", "<script>alert('" + ex.Message + "')</script>");}}
已验证通过可正常使用的，word转html：
private void ConvertWordToHtml(string sourcefile, string destfile) //sourcefile:原word文件路径,destfile:生成的html文件路径{Microsoft.Office.Interop.Word.Application word = new Microsoft.Office.Interop.Word.ApplicationClass();//Word.ApplicationClass word = new Word.ApplicationClass();Type wordType = word.GetType();Microsoft.Office.Interop.Word.Documents docs = word.Documents;// 打开文件Type docsType = docs.GetType();object fileName = sourcefile;Microsoft.Office.Interop.Word.Document doc = (Microsoft.Office.Interop.Word.Document)docsType.InvokeMember("Open",System.Reflection.BindingFlags.InvokeMethod, null, (object)docs, new Object[] { fileName, true, true });// 转换格式，另存为Type docType = doc.GetType();object saveFileName = destfile;//下面是Microsoft Word 9(11.0) Object Library的写法，如果是10(没试过)，可能写成：/*docType.InvokeMember("SaveAs", System.Reflection.BindingFlags.InvokeMethod,null, doc, new object[]{saveFileName, Word.WdSaveFormat.wdFormatFilteredHTML});*////其它格式：///wdFormatHTML///wdFormatDocument///wdFormatDOSText///wdFormatDOSTextLineBreaks///wdFormatEncodedText///wdFormatRTF///wdFormatTemplate///wdFormatText///wdFormatTextLineBreaks///wdFormatUnicodeTextdocType.InvokeMember("SaveAs", System.Reflection.BindingFlags.InvokeMethod,null, doc, new object[] { saveFileName, Microsoft.Office.Interop.Word.WdSaveFormat.wdFormatHTML });//关闭文档 docType.InvokeMember("Close", System.Reflection.BindingFlags.InvokeMethod,null, doc, new object[] { null, null, null }); // 退出 WordwordType.InvokeMember("Quit", System.Reflection.BindingFlags.InvokeMethod,null, word, null);//将html统一格式成gb2312TransHTMLEncoding(destfile);}
