因为几天我试图用拖放界面实现多个文件上传.我搜索了很多,最后从http://www.dropzonejs.com/找到了我的确切要求
我从上面的网站尝试了相同的步骤.但是,我无法在我的aspx页面中实现此dropzone功能.

假设您使用的是Web窗体,则需要实现一个页面,该页面读取已发布的文件数据并将其保存到文件中.
示例.ASPX
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="Mvc4Application_Basic.WebForm1" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<script src="https://raw.github.com/enyo/dropzone/master/downloads/dropzone.js"></script>
<link href="http://www.dropzonejs.com/css/general.css?v=7" rel="stylesheet" />
</head>
<body>
<form id="frmMain" runat="server" class="dropzone">
<div>
<div class="fallback">
<input name="file" type="file" multiple />
</div>
</div>
</form>
</body>
</html>

fileExtension = Path.GetExtension(fileName);
// IMPORTANT! Make sure to validate uploaded file contents, size, etc. to prevent scripts being uploaded into your web app directory
string savedFileName = Path.Combine(@"C:\Temp\", Guid.NewGuid().ToString() + fileExtension);
file.SaveAs(savedFileName);
