将文件传递到ASP.NET中的另一个项目

Question

I'm trying to create simple app for editing .xml files. I have created another project within one solution to which I'm trying to pass file, where I would like to edit and save it. But is that possible? I have tried to import System.web and then request HttpPostedFile as parameter of one function, but VS do not recognize such type there. What am I doing wrong?

Alternatively, what is better way to pass file from one project to another?

Answer 1

There are multiple ways to realize passing data between different classes.

One way is to pass it with a Stream , as System.File.Open ( MSDN ) already gives back a FileStream . With streams you need to be careful with the handling of opening, closing, reading etc (see using ).

Another way is by simply passing the path of the file as a string and open it elsewhere. But as you are trying to use a HttpPostedFile -object, I guess you're working on a project running on 2 different machines.

You should read into streaming data, and with streaming it's irrelevant if you got the data from a file, a request or even another stream.

Edit: It seems your main first problem here was that the class HttpPostedFile was in a assembly you didnt referenced before. You can get tips for situations like these by pressing Ctrl + . . VS suggests you things like creating a class for unknown objects or, if it's a common known object, adding references.
