推荐答案

我使用asp.net，并设计了一个人向我的saite注册时上传的图片他/她和那张照片保存在我项目根目录下的一个文件夹中.该文件夹名为Uploads
那是一些代码
<< br模式="hold"/>字符串t = Request.MapPath(〜/Uploads");
Directory.CreateDirectory(t +"\\" + u.UserNam);
FileUpload1.SaveAs(t +"\\" + u.UserNam +"\\ profile.jpg");
>>
现在我想使用该图像，当那个人登录时
我知道我应该使用Cookies，但我不知道如何使用?"

首先，不要将它们存储在根目录中-而是将它们放在子文件夹中.两个原因:
1)如果这样做，则根文件夹将变得非常拥挤，这会使您在更新站点时识别要替换的文件变得更加困难-将它们保存在单独的文件夹中，然后您就知道它们都只是相关的给用户，而不是网站的机械".
2)所有人都需要访问根文件夹中的所有文件-是否已登录.这意味着我无需登录即可轻松获取站点上每个用户图片的副本...子文件夹可以具有不同的保护.

第二，为什么要使用Cookie?它们用于保存会话或页面之间的数据-而不用于显示图像！

显示图像并不困难.这里有一个提示可以做到这一点:一个通用ASP.NET的Image-From-DB类 [

"I use asp.net and I design that when a person register to my saite , upload a picture of him/her and that picture save on a folder in the root of my project.that folder name is Uploads
some of thats code
<<<br mode="hold" />String t = Request.MapPath("~/Uploads");
Directory.CreateDirectory(t +"\\"+ u.UserNam);
FileUpload1.SaveAs(t+ "\\"+ u.UserNam + "\\profile.jpg");
>>
and now i want to use this image, when that person login
i know i should use the Cookies but I dont know how?"

First off, don''t store them in the root - put them in a subfolder instead. Two reasons:
1) If you do then the root folder will get very crowded with images, which can make it a lot harder to identify which files to replace when you update the site - keep them in a separate folder and then you know they are all only related to the user, and not to the "mechanics" of your site.
2) All files in the root folder need to be accessible to everybody - logged in or not. Which means that I could easily snatch a copy of every user picture on your site without logging in... Sub folders can have different protection.

Second, why would you want to use cookies? They are for saving data between sessions, or pages - not for displaying images!

Displaying the image isn''t difficult. There is a Tip here that does just that: A generic Image-From-DB class for ASP.NET[^] It retrieves them from a DB, but a file is just as simple and only needs a small change!
