如何使用ASP.Net和Jquery上载多个文件？

Question

I have added the following javascripts in my aspx page...

<script src="jquery-1.3.2.js" type="text/javascript"></script>
<script src="jquery.MultiFile.js" type="text/javascript"></script>

I have also added the following code in the button click operation.

 HttpFileCollection hfc = Request.Files;
    for (int i = 0; i < hfc.Count; i++)
    {
        HttpPostedFile hpf = hfc[i];
        if (hpf.ContentLength > 0)
        {
            hpf.SaveAs(Server.MapPath("MyFiles") + "\\" + System.IO.Path.GetFileName(hpf.FileName));
            Response.Write("<b>File: </b>" + hpf.FileName + " <b>Size:</b> " + hpf.ContentLength + " <b>Type:</b> " + hpf.ContentType + " Uploaded Successfully <br/>");
        }
    }

The problem is I can't select mulltiple files...!!!

 <asp:FileUpload id="FileUploadControl" class="multi" runat="server"/>
        <asp:Button ID="BtnUpload" runat="server" onclick="BtnUpload_Click" 
            Text="Upload" Width="105px" style="margin-top: 4px" />
        <asp:Label runat="server" id="StatusLabel" text="Upload status: " />

Answer 1

只是使其倍数

<asp:FileUpload id="FileUploadControl" Multiple="Multiple" class="multi" runat="server"/>

Answer 2

you should use AjaxFileUpload instead of file upload. This is an ajax control toolkit component. After that you create the event that will get each file. It alredy uploads and give to you the link that the file was uploaded.

    <%@ Register assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" tagprefix="asp" %>

  <ajaxToolkit:AjaxFileUpload ID="AjaxFileUpload1"
    ThrobberID="myThrobber"
    ContextKeys="Vinicius"
    AllowedFileTypes="jpg,jpeg"
    MaximumNumberOfFiles=10
    runat="server"/>
