使用Aspose把office文件转换为Html 文件转换方法如下：

/// <summary>
            /// office文件转换为Html
            /// </summary>
            /// <param name="extFileName">扩展名</param>
            /// <param name="sourceFile">源文件路径</param>
            /// <param name="desFile">目标文件</param>
            /// <returns></returns>
            public static string FileToHtmlFile(string extFileName, string sourceFile, string desFile)
            {
                if (string.IsNullOrEmpty(sourceFile))
                {
                    return "0";//没有文件
                }
    
                switch (extFileName.ToUpper())
                {
                    case "PPT":
                    case "PPTX":
                        Aspose.Slides.Presentation ppt = new Aspose.Slides.Presentation(sourceFile);
                        ppt.Save(desFile, Aspose.Slides.Export.SaveFormat.Html);
                        break;
                    case "DOC":
                    case "DOCX":
                        Aspose.Words.Document doc = new Aspose.Words.Document(sourceFile);
                        doc.Save(desFile, Aspose.Words.SaveFormat.Html);
                        break;
                    //case "XLS":
                        //case "XLSX":
                       //    break;
                }
                return "ok";
            }

PPT文件生成的html 会出现编码识别错误 导致浏览器网页乱码

解决方法如下，

System.IO.StreamReader sr = new System.IO.StreamReader(strFilePath);
                    string html = sr.ReadToEnd();
                    sr.Close();
                    System.IO.StreamWriter sw = new System.IO.StreamWriter(strFilePath, false);
                    //System.IO.StreamWriter sw = new System.IO.StreamWriter(strFilePath, false, Encoding.UTF8);
                    //特别重要：添加编码标志，解决浏览器识别错误
                    html = html.Replace("<meta http-equiv=\"X-UA-Compatible\" content=\"IE=9\">", "<meta http-equiv=\"X-UA-Compatible\" content=\"IE=9\"><meta http-equiv=\"Content-Type\" content=\"text/html; charset=utf-8\" />");
                    //去除试用标志
                    html = html.Replace("Evaluation only", "");
                    html = html.Replace("Created with Aspose.Slides for .NET 2.0 14.8.1.0.", "");
                    html = html.Replace("Copyright 2004-2014 Aspose Pty Ltd.", "");
                    //html = html.Replace("Evaluation Only. Created with Aspose.Words. Copyright 2003-2014 Aspose Pty Ltd.", "");
                    html = html.Replace("Evaluation Only. Created with Aspose.Words. Copyright 2003-2014 Aspose Pty Ltd.", "");
                    html = html.Replace("This document was truncated here because it was created using Aspose.Words in Evaluation Mode.", "");
                    // < meta http - equiv = "X-UA-Compatible" content = "IE=9" >< meta http - equiv = "Content-Type" content = "text/html; charset=utf-8" />
                    sw.Write(html);
                    sw.Close();
