BS实现文件夹上传下载_终结篇
前两篇《BS文件夹上传操作(二) ——基本功能实现》，《BS文件夹上传操作 》现在来看只能做了解了。真正可以运用到项目中的，只能是这篇ActiveX。
在这里还是要感谢 Left join.G 下。因为没有他的帮忙还不知道这个需求是否能完成。另外这个功能的实现也是我们团队的成果。
Tom，Ryan……两位我心中的高手！
Web实现文件夹上传，下载功能，具体涉及到两个核心内容ActiveX、WebClient
一、ActiveX 核心部分
定义：ActiveX是Microsoft对于一系列策略性 面向对象程序技术和工具的称呼，其中主要的技术是 组件对象模型（COM）。
打开VS
A、新建一个Windows窗体控件库
B、项目属性-应用程序-程序集信息
C、项目属性-生成
再把AssemblyInfo.cs添加
[assembly: AllowPartiallyTrustedCallers()]//如果希望程序集被部分受信任的代码调用
接下来编码开始 ……

接口IObjectSafety.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.InteropServices;
namespace FumaWindowsLibrary
{
[ComImport, GuidAttribute("CB5BDC81-93C1-11CF-8F20-00805F2CD064")]
[InterfaceTypeAttribute(ComInterfaceType.InterfaceIsIUnknown)]
public interface IObjectSafety

[PreserveSig()]
int SetInterfaceSafetyOptions(ref Guid riid, [MarshalAs(UnmanagedType.U4)] int dwOptionSetMask, [MarshalAs(UnmanagedType.U4)] int dwEnabledOptions);
}
}
核心部分运行效果：
如果你的项目要引用ActiveX 具体内容可baidu，google 就知道了……
二、WebClient
MSDN: WebClient 类提供向 URI 标识的任何本地、Intranet 或 Internet 资源发送数据以及从这些资源接收数据的公共方法。
核心是Asp.Net 站点文件传输
1。 发起端：
System.Net.WebClient webclient = new System.Net.WebClient();
webclient.UploadFile(filePath, "POST", fileuri);//filePath接收端地址 eg：FolderUploader.ashx
2。接收端（FolderUploader.ashx）
void Page_Load(object sender, EventArgs e)
{
foreach(string f in Request.Files.AllKeys)
{
HttpPostedFile file = Request.Files[f]; file.SaveAs(@"c:\" + file.FileName);
}
}
如果你的项目中有类似的需求，上面的那过去再自由发挥下其他，基本上OK！
以上，可以根据自己的需求实现文件夹上传，下载（单个文件上传下载直接拖拽控件）
再看看我们的项目及功能实现
思路决定出路
不管做什么，思想最重要，有了想法就会有方法，大体说下我们所用到的思路……
导入：在ActivceX中当用户选择某一文件夹，先查找该文件夹下的文件及文件夹（递归查找）再组合成Table最后循环Table并调用WebClient.UploadFile方法（UploadFile：将本地文件发送到资源并返回包含任何响应的字节数组）实现文件夹上传功能。
导出：则需要通过客户端选择下载的路径以参数形式传递到ActiveX中，导出可分两种：文件、文件夹
文件：单个文件，则直接传递文件的绝对路径。DownloadFile(filePath, selectPath)//selectPath文件的绝对保存路径 filePath文件被下载的路径
文件夹：文件夹复杂些，因为文件夹中可能包含文件，文件夹……在客户端把文件夹（递归）以json格式传递到ActiveX中并转换成Table并进行相关导出工作
如果不清楚，看看下面代码
一、AvtiveX
进行了一些扩展，另外接口还是上面的IObjectSafety

一般处理程序FolderUploader.ashx（用于导入）filePath就是FolderUploader.ashx 注意：如果你要上传到服务器端一定要绝对路径例如：http://192.×.××.××:××××/FolderUploader.ashx
ActiveX 方法
public string OpenFolderdialog(string filePath)
{
……………………
System.Net.WebClient webclient = new System.Net.WebClient();
webclient.UploadFile(filePath, "POST", fileuri);

效果：
《BS文件夹上传操作(二) ——基本功能实现》功能是实现了，但是部署到服务器端，出现了问题。上传，下载 选择的是客户端，但是后台执行时默认的选择了服务器端。另外安全性不是很好。需要对浏览器进行安全设置。
如果你的需求中也是这样，希望这篇可以给你带来帮助……
