ASP. NET 5 upload file stored via virtual path

Put the code on first.

[HttpPost] Publiciactionresult importteaching (iformfile file) {stringRoot =@"temp/teachingfile/"; stringPhypayh =EVN.            MapPath (root); if(File! =NULL)            {                varParsedcontentdisposition =contentdispositionheadervalue.parse (file.                Contentdisposition); varOriginalname = ParsedContentDisposition.FileName.Replace ("\"",""); File. SaveAs (Phypayh+originalname); }            Else{modelstate.addmodelerror ("","No file selected"); returnView (); }            returnRedirecttoaction ("Index"); }

You must first get the ihostingenvironment inside the service.

The following code

  [fromservices]        publicsetget;}

Note: this

Ihostingenvironment is automatically registered to the service when it is started. can be directly obtained

Special attention:

Now the virtual path is written in a different way before the MVC5 is similar:string root = "~/livefile/";

Now is:string root = "livefile/";

I have tried many times before in accordance with MVC5 's wording.
