asp.net core mvc实现文件上传实例

工作用到文件上传的功能，在这个分享下 ~~

Controller:        

public class PictureController : Controller
  {
    private IHostingEnvironment hostingEnv;

    public PictureController(IHostingEnvironment env)
    {
      this.hostingEnv = env;
    }
    // GET: //
    public IActionResult Index()
    {
      return View();
    }
    public IActionResult UploadFiles()
    {
      return View();
    }
    [HttpPost]
    public IActionResult UploadFiles(IList files)
    {
      long size = 0;
      foreach (var file in files)
      {
 var filename = ContentDispositionHeaderValue
  .Parse(file.ContentDisposition)
  .FileName
  .Trim('"');
 //这个hostingEnv.WebRootPath就是要存的地址可以改下
 filename = hostingEnv.WebRootPath + $@"{filename}";
 size += file.Length;
 using (FileStream fs = System.IO.File.Create(filename))
 {
   file.CopyTo(fs);
   fs.Flush();
 }
      }
      ViewBag.Message = $"{files.Count} file(s) /{ size}bytes uploaded successfully!";
return View();
    }

  }

view:

下面是jquery ajax方式上传的

post方式的action的z参数没用 因为只有一个post方式的会404错误所以又加了一个get的action

Controller: 

    public IActionResult UploadFilesAjax()
    {
      return View();
    }
    [HttpPost]
    public IActionResult UploadFilesAjax(string z) 
    {
      long size = 0;
      var files = Request.Form.Files;
      foreach (var file in files)
      {
 var filename = ContentDispositionHeaderValue
  .Parse(file.ContentDisposition)
  .FileName
  .Trim('"');
 filename = @"C:Userslg.HLDesktop" + $@"{filename}";    
 size += file.Length;
 using (FileStream fs = System.IO.File.Create(filename))
 {
   file.CopyTo(fs);
   fs.Flush();
 }
      }
      string message = $"{files.Count} file(s) / { size}bytes uploaded successfully!";
 return Json(message);
    }

view
