Import excel file with asp.net

I'm working on an asp.net /c# app

I need my app to allow users to upload .XLS files (located on the user machine).

How can i read data from the .XLS file but withou开发者_Python百科t saving the file on server?

In order to be able to do something with the file on the server (eg using ASP.net ) you will have to at least temporarily save the file on the server. Although an apache module might let you interupt the stream as it is uploaded, but thats probably a bit ott.

There MAY be something you could do in Javascript but I doubt it.

An idea would be to parse .csv files, if it possible. I can send example. Also you can parse .XLS files through interop excel dll. But it very slow method.
