c# - Request.Files - get the first File without foreach cycle -


i'm new in web. action:

[httppost]  public virtual actionresult savefile(ienumerable<vacationschedule.models.vacationtypeviewmodel> vacationtypes)         {             foreach (string filename in request.files)             {                 httppostedfilebase file = request.files[filename];                 string type = file.contenttype;                 string nameandlocation = "~/documents/" + system.io.path.getfilenamewithoutextension(file.filename);                 file.saveas(server.mappath(nameandlocation));             }                   return view(mvc.admin.actionnames.documents);         }

question: know in request.files can 1 file. exist way file without foreach cycle?

you can use firstordefault extension method:

 string filename = request.files.firstordefault();  if (!string.isnullorempty(filename)) { }

or ternary operator index accessor:

string filename = request.files.count > 0 ? request.files[0] : null;
