Answer 1

适当修改一下即可. #region 上传文件到数据库和服务器

                    string fileName = "";//定义文件名
                    //string fileExtension = "";
                    fileName = Path.GetFileName(postedFile.FileName);//得到上传文件的完整名称 即文件名+后缀名
                    int index = fileName.IndexOf(".");

                    //FileTypeImg = "../FileTypeimg/" + hz + ".gif";

                    if (postedFile.ContentLength > 2097151 * 1024)//判断是否大于配置文件中的上传文件大小

if (FileUpload1.HasFile)
