System.IO.Directory.CreateDirectory(createfolder);
AsyncFileUpload1.SaveAs(Server.MapPath("/tmp/jobres/" + AsyncFileUpload1.PostedFile.FileName));

but how to store my file in created folder?

Answer 1

Since you are using MapPath on save, your directory may be created in the wrong spot. You should be using MapPath when creating your directory as well:

var createfolder = Path.Combine(Server.MapPath("/tmp/jobres/"), uId.ToString());    
System.IO.Directory.CreateDirectory(createfolder);
AsyncFileUpload1.SaveAs(Path.Combine(createdFolder, AsyncFileUpload1.PostedFile.FileName));

Answer 2

 string createfolder = "/tmp/jobres/" + uId;                           
 System.IO.Directory.CreateDirectory(createfolder);
 AsyncFileUpload1.SaveAs(Path.Combine(createfolder,AsyncFileUpload1.PostedFile.FileName));
