public class UploadController : Controller
{
private IHostingEnvironment _hostingEnv;
public UploadController(IHostingEnvironment hostingEnv)
{
_hostingEnv = hostingEnv;
}
[HttpPost]
public IActionResult Index()
{
var file = Request.Form.Files;
if (file.Sum(f => f.Length) > )
{
foreach (var pic in file)
{
var picname = ContentDispositionHeaderValue
.Parse(pic.ContentDisposition)
.FileName
.Trim('"');
var exname = picname.Substring(picname.LastIndexOf("."));
var picfullname = DateTime.Now.ToString() + exname;
picname = _hostingEnv.WebRootPath + $@"\UploadImg\{picfullname}"; using (FileStream fs = System.IO.File.Create(picname))
{
pic.CopyTo(fs);
fs.Flush();
}
}
} return Content("ok");
}
}

2.Asp.Net Mvc方式

public class UploadController : Controller
{
[HttpPost]
public ActionResult Index(HttpPostedFileBase picture)
{
if (picture.ContentLength > )
{
string filePath = Path.Combine(HttpContext.Server.MapPath("../UploadImg"),
Path.GetFileName(picture.FileName));
picture.SaveAs(filePath);
}
return Content("ok");
}
