A while ago I answered a question about uploading files from an ASP.net application on walla.co.il … So here is the tip: To let your users upload files from their computer to the server you can use a great contol called “FileUpload” control. To use the control, just put the code below into the POST event and the file that the user asked to upload will be uploaded to the server: (Note: oFile is the FileUpload control) PHP: if (oFile.PostedFile != null) { string fullFileName = oFile.PostedFile.FileName; //getting the path string fileName = System.IO.Path.GetFileName(fullFileName); //getting the filenameoFile.PostedFile.SaveAs(Server.MapPath(string.Empty) + “\\” + fileName); //saving the file on the demand directory on the server file system } Note: this code checks if a file was really sent before trying to save it.
