上面是前端页面，下面添加后台处理程序
/// <summary> /// 保存上传文件 /// </summary> /// <param name="sqlpath">路径</param> /// <returns></returns> public ActionResult SaveFile(string sqlpath) { //获取前端传过来的文件 var files = HttpContext.Request.Files; //设置上传文件存储的文件名 string str = "files"; //获取当前程序运行的物理地址 string uploadPath = HttpRuntime.AppDomainAppPath.ToString() + str + "\"; for (int i = 0; i < files.Count; i++) { HttpPostedFileBase file = files[i]; if (file != null) { if (!Directory.Exists(uploadPath)) { Directory.CreateDirectory(uploadPath); } string name = file.FileName; string ext = Path.GetExtension(name); string newname = DateTime.Now.ToString("yyyyMMddHHmmssfff") + ext; sqlpath = "../" + str + "/" + newname; string fullName = uploadPath + newname; file.SaveAs(fullName); //string len1 = GetMediaTimeLen(fullName); //获取视频的秒数 int videoSeconds = GetMediaTimeLenSecond(fullName); //往数据库里面进行存储 videoSave vs = new videoSave(); vs.guid = Guid.NewGuid().ToString(); vs.videoPath = sqlpath; vs.videoLengthTime = videoSeconds; vs.videoHasTime = 0; vs.videoStatus = "未观看"; db.Entry(vs).State = EntityState.Added; db.SaveChanges(); } } return Json(sqlpath, JsonRequestBehavior.AllowGet); }
下面这个是获取视频文件总时长的方法,按照秒数进行计算，计算出一共多少秒，返回 “15” 类似的数据 注:这个例子是使用的这个方法
/// <summary> /// 获取视频的秒数 /// </summary> /// <param name="path">该视频对应的路径</param> /// <returns></returns> public static int GetMediaTimeLenSecond(string path) { System.Type objType = System.Type.GetTypeFromProgID("Shell.Application"); dynamic shell = System.Activator.CreateInstance(objType); //文件路径 dynamic folder = shell.NameSpace(path.Substring(0, path.LastIndexOf("\"))); //文件名称 dynamic folderitem = folder.ParseName(path.Substring(path.LastIndexOf("\") + 1)); string len; if(Environment.OSVersion.Version.Major>=6) { len = folder.GetDetailsOf(folderitem, 27); } else { len = folderitem.GetDetailsOf(folderitem, 21); } string[] str = len.Split(new char[] { ':' }); int sum = 0; sum = int.Parse(str[0]) * 60 * 60 + int.Parse(str[1]) * 60 + int.Parse(str[2]); return sum; }
再添加一个获取视频文件总时长的方法，会返回“00:00:12”类似的数据
/// <summary> /// 获取视频时长 /// </summary> /// <param name="path">该视频对应的路径</param> /// <returns></returns> public static string GetMediaTimeLen(string path) { System.Type objType = System.Type.GetTypeFromProgID("Shell.Application"); dynamic shell = System.Activator.CreateInstance(objType); //文件路径 dynamic folder = shell.NameSpace(path.Substring(0, path.LastIndexOf("\"))); //文件名称 dynamic folderitem = folder.ParseName(path.Substring(path.LastIndexOf("\") + 1)); if(Environment.OSVersion.Version.Major>=6) { return folder.GetDetailsOf(folderitem, 27); } else { return folder.GetDetailsOf(folderitem, 21); } }
运行结果:
