Upload document to sharepoint library using HttpFileCollection
Hello everybody,
Today I post this article to client can upload document from their computer, if we use FileUpload1.PostedFile.FileName method we can’t upload document. Because, that code only execute in server (server setup sharepoint). So I write this article using HttpFileCollection. See details:
