</html>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 = ; 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 = ;
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(, path.LastIndexOf("\\")));
//文件名称
dynamic folderitem = folder.ParseName(path.Substring(path.LastIndexOf("\\") + ));
string len;
if(Environment.OSVersion.Version.Major>=)
{
len = folder.GetDetailsOf(folderitem, );
}
else
{
len = folderitem.GetDetailsOf(folderitem, );
}
string[] str = len.Split(new char[] { ':' });
int sum = ;
sum = int.Parse(str[]) * * + int.Parse(str[]) * + int.Parse(str[]);
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(, path.LastIndexOf("\\")));
//文件名称
dynamic folderitem = folder.ParseName(path.Substring(path.LastIndexOf("\\") + ));
if(Environment.OSVersion.Version.Major>=)
{
return folder.GetDetailsOf(folderitem, );
}
else
{
return folder.GetDetailsOf(folderitem, );
}
}
运行结果:
