C＃-如何更改名称为空格字符（“”）的文件夹的属性？

Question

In C#, for changing attribute of folder, I use FileAttributes. Example:

myfolder= "C:\\Test Programs\\Avatar";
DirectoryInfo ss = new DirectoryInfo(myfolder);
ss.Attributes = FileAttributes.Normal;

--> Done! Attribute of Avatar is Normal.

But, with some folder which name are " ":

myfolder= "C:\\Test Programs\\ ";

My program doesn't throw any errors but attribute of that folder isn't change. What can i do?

(some viruses created a hidden folder with name is " " and moved all data on usb flash disk into it. I want to remove hidden attribute of that folder)

My English grammar isn't good. Sorry about that!

Answer 1

Done!. I added "\\\\" into myfolder. With folder Avatar --> myfolder= "C:\\\\Test Programs\\\\Avatar\\\\";

With folder which name is " " --> myfolder= "C:\\\\Test Programs\\\\ \\\\";

And my program set Attribute of that folder to Normal.

Thanks every one!.

Try adding + System.Net.WebUtility.HtmlDecode(@" ") +"\\\\" to the end of your directory name instead of the space.

Your string will look like this: myfolder= "C:\\\\Test Programs\\\\ " + System.Net.WebUtility.HtmlDecode(@" ") + "\\\\";
