推荐答案

的<一个href=\"http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.fileupload.allowmultiple(v=vs.110).aspx\"><$c$c>FileUpload.AllowMultiple物业的 .NET 4.5及更高版本将允许您控制选择多个文件。

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及以下

.NET 4 and below

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

在后回，则可以：

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
