Upload file using the new FileUpload control in ASP.NET

          In ASP.NET you could upload files using the HTML FileUpload server control.This control put an <input type = " file " > element on your Web page to enable the end user to upload files to the server.To use the file ,however,you had to make a couple of modifications to the page.For example , you were required to add enctype = " multipart/form-data " to the page's <form> element.
           ASP.NET introduces a new FileUpload server control that makes the process of uploading files to a server even simpler.When giving a page the capability to upload files ,you simplay include the new < asp : FileUpload > control and ASP.NET thake care of the rest,including adding the enctype attribute to the page's < form > element
The following code shows the Uploading files using the new FileUpload control

VB


<script runat = " server ">
          protected Sub Button1_Click( ByVal sender As object , ByVal e As System.EventArgs )
                  if FileUpload1.hasFile Then
                         Try
                                 FileUpload1.SaveAs (" C:\Uploads\" & _
                                        FileUpload1.FileName )
                                 Label1.Text = "File Name: " & _
                                        FileUpload1.PostedFile.FileName & "<br>" & _
                                        "File Size: " & _
                                        FileUpload1.PostedFile.ContentLength & " kb<br> " & _
                                        "Content type : " & _
                                        FileUpload1.PostedFile.ContentType
                          Catch ex As Exception
                                 Label1.Text = "ERROR: " & ex.Message.ToString( )
                           End Try
                   Else
                            Label1.Text = "You have not specified a file. "
                    End If
           End Sub
