Sharepoint 2010 - File Uploading with HttpFileCollection

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:
