我做的试验代码：
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="Demo._Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<script language="JavaScript">
function addFile()
{
var str = ' <INPUT type="file" size="50" NAME="File">'
document.getElementById('MyFile').insertAdjacentHTML("beforeEnd",str)
}
</script>
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Untitled Page </title>
</head>
<body>
<form id="form1" runat="server" enctype="multipart/form-data">
<input type="button" value="增加(Add)" onclick="addFile()">
<input onclick="this.form.reset()" type="button" value="重置(ReSet)">
<asp:Button Runat="server" Text="上传" ID="Upload" OnClick="Upload_Click1" > </asp:Button>
<div id="MyFile">
<input type="file" name="File" />
</div>
</form>
