推荐答案

我用Jtable上传了.mp3音频文件

以下代码更改已完成



[HttpPost]

public JsonResult UploadAudiofiles（Album C，tbl_Save_Song tb，HttpPostedFileBase file）

{

var path = string.Empty;

string subPath = string.Empty;

var destinationPath = string。清空;

var fname = string.Empty;

ActionResponse response = new ActionResponse（）;

HttpPostedFileBase postedFile = Request.Files [file ];



if（file.ContentLength> 0）

{

if（ModelState.IsValid ）

{

if（System.IO.File.Exists（tb.SongName））

{

返回Json（jTable.FileExit）;

}



var fileName = Path.GetFileName（file.FileName）;

int MaxContentLength = 2048576000;



string [] AllowedFileExtension = new string [] {。mp3};

if（ ！AllowedFileExtension.Contains

（file.FileName.Substring（file.FileName.LastIndexOf（'。'））））

{

ModelState .AddModelError（文件，请文件类型：+ string.Join（，，AllowedFileExtension））;

}

else if（file.ContentLength > MaxContentLength）

{

ModelState.AddModelError（文件，您的文件太大，允许的最大大小为：+ MaxContentLength +MB）;

}

其他

{





subPath =/ Albums /+ C.AlbumID;

bool exists = Directory.Exists（Server.MapPath（subPath））;

if（！exists）

subPath =/ Albums /+ C.AlbumID;

Directory.CreateDirectory（Server.MapPath（subPath））;



fileName = fileName.ToString（）;



response.Status = ActionResponse._SUCCESS;

response.Message = fileName;



ModelState.Clear（）;

ViewBag.Message =文件已成功上传。文件路径：/相册/+文件名;



}

}

}

else

{

ModelState.AddModelError（CustomError，Http发布的文件数据返回空数据）;

}



返回Json（响应，JsonRequestBehavior.DenyGet）;



}

I done the uploading the .mp3 audio file with Jtable
below code is changes was done

[HttpPost]
public JsonResult UploadAudiofiles(Album C, tbl_Save_Song tb, HttpPostedFileBase file)
{
var path = string.Empty;
string subPath = string.Empty;
var destinationPath = string.Empty;
var fname = string.Empty;
ActionResponse response = new ActionResponse();
HttpPostedFileBase postedFile = Request.Files["file"];

if (file.ContentLength > 0)
{
if (ModelState.IsValid)
{
if (System.IO.File.Exists(tb.SongName))
{
return Json(jTable.FileExit);
}

var fileName = Path.GetFileName(file.FileName);
int MaxContentLength = 2048576000;

string[] AllowedFileExtension = new string[] { ".mp3" };
if (!AllowedFileExtension.Contains
(file.FileName.Substring(file.FileName.LastIndexOf('.'))))
{
ModelState.AddModelError("File", "Please file of type:" + string.Join(",", AllowedFileExtension));
}
else if (file.ContentLength > MaxContentLength)
{
ModelState.AddModelError("File", "Your file is too large,maximum allowed size is:" + MaxContentLength + "MB");
}
else
{


subPath = "/Albums/" + C.AlbumID;
bool exists = Directory.Exists(Server.MapPath(subPath));
if (!exists)
subPath = "/Albums/" + C.AlbumID;
Directory.CreateDirectory(Server.MapPath(subPath));

fileName = fileName.ToString();

response.Status = ActionResponse._SUCCESS;
response.Message = fileName;

ModelState.Clear();
ViewBag.Message = "File uploaded Successfully. File path: /Albums/" + fileName;

}
}
}
else
{
ModelState.AddModelError("CustomError", "Http posted file data returns null data");
}

return Json(response, JsonRequestBehavior.DenyGet);

}
