How to choose multiple files using File Upload Control?

Question

I have a file upload control.Now on clicking on that, I want to select multiple files.

How can I do so?

Answer 1

The FileUpload.AllowMultiple property in .NET 4.5 and higher will allow you the control to select multiple files.

<asp:FileUpload ID="fileImages" AllowMultiple="true" runat="server" /> 

.NET 4 and below

 <asp:FileUpload ID="fileImages" Multiple="Multiple" runat="server" /> 

On the post-back, you can then:

 Dim flImages As HttpFileCollection = Request.Files                     For Each key As String In flImages.Keys     Dim flfile As HttpPostedFile = flImages(key)     flfile.SaveAs(yourpath & flfile.FileName)  Next
