问题描述

大家好，

看看下面的代码:

Hi Every one,

Have a look at the below code:

if (File.Exists(temppath))
 {
if (File.Exists(Server.MapPath("Documents") + "/" + dt.Rows[0]["ImagePath"].ToString()))
 {
   File.Delete(Server.MapPath("Documents") + "/" + dt.Rows[0]["ImagePath"].ToString());
 }
  File.Copy(temppath, Server.MapPath("Documents") + "/" + dt.Rows[0]["ImagePath"].ToString());                
 }

在这里，在以下

Here, in the following

Server.MapPath("Documents")

文档"是我的应用程序中的文件夹名称，文件正在其中存储..

推荐答案

您可以对物理路径进行硬编码.即D://YourFolderPath.但是请务必在使用前验证其存在.如果在该路径不可用的情况下可能会引发错误.

但这不是一个好方法.如果必须使用它，那么我建议您将此路径保存在web.config或应用程序配置中.因此，如果需要，将来可以很容易地对其进行更改.

还有一件事，您必须具有从该指定文件夹添加/编辑/删除文件的权限.

希望对您有所帮助.

You can hardcode the physical path. i.e. D://YourFolderPath. But be sure to verify its existence before using it. As it might raise error in case when that path is unavailable.

But this is not a good approach. If it is a must for you to use, then I would recommended you to save this path in web.config or application config. So it would be easy for you to change it in future if required.

One more thing, you must have permission to add/edit/delete files from that specified folder.

Hope it helps.
