dotfuscator.exe-VS2005自带的代码混淆器

大家都知道编译后的代码很容易被破译，那么如何保证辛辛苦苦做好的工程不被轻易破译吗？那就选用dotfuscator.exe吧
文件在C:\Program Files\Microsoft Visual Studio 8\Application\PreEmptive Solutions\Dotfuscator Community Edition\dotfuscator.exe

使用
1、打开VS2005。
2、点击dotfuscator，它会提示要求注册，可先不注册。
3、具体设置比较简单，这里不细说了。


原C#代码

        protected void doUpload()
        {
            try
            {
                HttpPostedFile file = this.file1.PostedFile;
                string fileContentType = file.ContentType; //文件类型
                string fileExtension = System.IO.Path.GetExtension(file.FileName).ToLower(); //上传文件的扩展名
                string F_Type = fileExtension.Substring(1, fileExtension.Length - 1);
                string strNewPath = DateTime.Now.ToString("yyyyMMddHHmmssffff") + GetExtension(file.FileName);
                file.SaveAs(Server.MapPath(picServer + strNewPath));
                string FullPath = picServer + strNewPath;
                string jsstr = "";
                jsstr += "parent.uploadsuccess('" + FullPath + "','" + itemID + "');";

                if (fileContentType == "image/bmp" || fileContentType == "image/gif" || fileContentType == "image/pjpeg")
                {
                    if (add2ThumbImg.Checked == true) //设为缩略图
                    {
                            jsstr += "parent.add2ThumbImg('" + F_Type + "','" + FullPath + "');\r\n";
                            jsstr += "parent.setUploadImg('" + F_Type + "','" + FullPath + "');\r\n";

                    }

                }
                if (ChannelType != "Article")
                {
                    jsstr += "parent.addDownUrl('" + ChannelType + "','" + FullPath + "');\r\n";
                }
                else //插入文章内容
                {
                    jsstr += "parent.addUploadItem('" + F_Type + "','/','" + FullPath + "','300');\r\n";
                }
                WriteJs(jsstr);

            }
            catch
            {
                WriteJs("parent.uploaderror();");
            }
        }
