c# - Async image file save -

in web mvc project.

i have following function trying make async save many files , bit slow. need add list of tasks , await all:

   var fs = new filesaver();         property.floorplanpath = fs.savefile(propertyrentalform.floorplanfile, "~/uploads/properties/floorplans");         property.floorplan2path = fs.savefile(propertyrentalform.floorplan2file, "~/uploads/properties/floorplans");         property.epcpath = fs.savefile(propertyrentalform.epcfile, "~/uploads/properties/epc");      public string savefile(httppostedfilebase file, string uploadpath)     {          if (file == null || file.contentlength <= 0) return "";         var filename1 = path.getfilename(file.filename);         if (filename1 == null) return "";         // clean file name         filename1 = string.format("{0}{1}",             path.getfilenamewithoutextension(filename1).getaliastitle(),             path.getextension(filename1));          var path = path.combine(httpcontext.current.server.mappath(uploadpath), filename1);         file.saveas(path);         return filename1;     } 

if have single disk save files there no meaning make async. because have limited disk i/o. can use queue mechanism , can check queue status asynchronously...
