Read-only directories in C#

[vrsantos]

Hi.

How can I verify if a given directory is read-only in C# ? I tried it using this approach:

DirectoryInfo d = new DirectoryInfo(@ "C:\Test");
if (d.Attributes == FileAttributes. ReadOnly)
// do something

But it doesn't works, even if I set manually (in Windows) the directory to read-only. The attribute is always 'Directory'.
One way of doing that is trying to create a subdirectory (with d.CreateSubdire ctory) wrapped by try/catch statements, and catching an eventual UnauthorizedAcc essException, but I don't think it's a good practice.

Can anyone help me?

Thanks in advance.

Read only for who?
Unless you set the readonly attribute with "attrib", it only makes a special rule based on the windows user.
For that, you should probably get the ACL for it and look through those.
