How to convert System.Web.UI.WebControls.FileUpload to System.string?
-
Hello, I'm making a bulletin board with multi-file upload. when I click Edit button, I would like to show files that I uploaded on ListBox. so, I used both of "System.Web.UI.HtmlControls.HtmlInputFile" and "System.Web.UI.WebControls.FileUpload". this is my code. static public ArrayList hif = new ArrayList(); for(System.Web.UI.WebControls.FileUpload HIF in hif) { ... } hif.Add(ListBox1.SelectedValue); It gives error cannot convert System.Web.UI.WebControls.FileUpload to System. I know ListBox1.SetectedValue is string data type. How can I convert System.Web.UI.WebControls.FileUpload to System.string? p.s. I tried to use like this . (FileUpload)ListBox1.SelectedValue. but that can't be converted. Thanks.

You can call ToString(), but I doubt that's what you want. I assume you want to select the Filename property on the object. I thikn you need a good book on OO before you do any more work.
