使用C＃和ASP.NET保存到Dropbox文件夹

Question

I have an MVC 4 application that generates excel spreadsheets from a template stored on my shared hosting FTP, but I would like the generated files to be stored in the user's dropbox folder, not the server. How can I accomplish this using C#?

My files are currently saved as follows:

ExcelPackage p = new ExcelPackage(tempFile);

string newpath = Path.Combine(Server.MapPath("~/Content"), "Invoice.xlsx");
            FileInfo newFile = new FileInfo(newpath);
            p.SaveAs(newFile);

tempFile is the template, which isnt relevant here. This code stores it on the server which I don't want.

Answer 1

You can do this by using the DropBox API .

Unfortunately there is no official API for .Net, but you can find some on the Web like:

• SharpBox
• DropNet

I let you check how they work and determine which one is more appropriate to your project, but by looking at the DropBox PHP API it doesn't seem very difficult. It is based on HTTP and OAuth.

Answer 2

You will not have any C# code running on the client in a web application and very doubtful you'd get the permission in any web application. What you'd might want to consider is offer the user to download the file, suggesting they put it in their dropbox folder.
