如何上传文件以及如何从文件夹下载?

How to upload a file and how to download from folder?

推荐答案

看看这些

设计页面

<asp:FileUpload ID="flUpload" runat="server" />

背后的代码

Code behind

protected void submit_Click(object sender, ImageClickEventArgs e)
    {
        string ID=textbox1.text;
        flUpload.SaveAs(Server.MapPath("user_doc/" + ID + ".doc"));
    }

假设这是ASP，然后在页面上放置FileUpload控件，并处理OnClick事件:

Assuming this is ASP, then place a FileUpload control on your page, and handle the OnClick event:

string filename = Path.GetFileName(MyFileUpload.FileName);
MyFileUpload.SaveAs(Mypath + filename);

要下载该文件，只需在您的网页顶部添加一个文件链接-其余的将由客户端浏览器完成.

To download it, just add a link to the file top your web page - the client browser will do the rest.
