HttpPostedFileBase.SaveAs method question

Question

Hi all,

I've got an asp.net mvc application that uploads a file and stores them in one of the directories where the website is located.

My question is... When you execute HttpPostedFileBase.SaveAs() method saving it with the same name as an existing filename on the folder, does HttpPostedfileBase overwrite the file?

Thanks a million!

Answer 1

Yes. Any existing file will be overwritten. (I checked the source)

Answer 2

HttpPostedFileBase is just an abstract base class - what SaveAs does depends on the implementation. However, it's clearly meant to abstract HttpPostedFile, and that will overwrite any files at the target location - if it can (i.e. has the appropriate permissions).
