在Asp.net中运行时创建目录及其子目录 [英] Create Directory and its subDirectory at runtime in Asp.net

问题描述

我想在根文件夹中创建运行时目录。通过这段代码

string strDate = DateTime.Now.ToString（dM-yyh：mm：ss.ffftt）。ToString（）;

Directory.CreateDirectory（Server .MapPath（〜/ Images / Work /）+ ddl_category.SelectedItem.Text）.CreateSubdirectory（strDate）;



但是我收到了一些错误。所以请问我，如何在运行时创建带有子文件夹的目录。

推荐答案

如果你想从服务器创建目录，请确定你的asp。 net用户对此目录具有访问权限，您可以通过右键单击根目录检查它并检查安全选项卡，或者使用IIS或目标Web服务器工具进行检查，之后您可以看到如何创建目录的链接。运行时间代码：

问题是你正在尝试创建一个包含'：'字符的目录。这里：

The problem is you are trying to create a directory that contains ':' characters. Here:

string strDate = DateTime.Now.ToString("d-M-yyh:mm:ss.ffftt").ToString();

这是不可能的。

您应该重新考虑与NTFS文件系统兼容的命名方案。



请参阅 NTFS命名约定 [ ^ ]



（此外，为什么要两次调用ToString（）方法？你不相信第一次调用返回字符串值吗？）

That is not possible.
You should rethink the naming scheme for one that is compatible with NTFS filesystem.

Please see NTFS Naming Conventions[^]

(Moreover, why do you call ToString() method twice? Don't you trust the first call to return a string value?)
