c# delete directory containing read only files

[gl]

I'm trying to delete a directory that contains readonly files. Is there any
easy way to do this? I get a System.Unauthor izedAccessExcep tion when a read
only file is encountered. Is there a way to make c# ignore a read only flag,
or perhaps set the read only flag for the directory and have it apply to all
files?

just wondering what the standard work around to this issue was.

Thanks

Use the File class to set the Read attribute?

So the only way is to loop through all files in the directory and set the
readonly attribuite to read? That's fine. Is there a way to set a
directory/folder's read only attribute?

Use System.Manageme nt and the WMI Win32_Directory class, which has no such
restriction.

using System.manageme nt;
....

string path = @"f:test\\";
string dirObject = String.Format(" win32_Directory .Name='{0}'", path);
using(Managemen tObject dir = new ManagementObjec t(dirObject))
{
dir.Get();
ManagementBaseO bject outParams = dir.InvokeMetho d("Delete", null,
null);
// ReturnValue should be 0, else failure
if(Convert.ToIn t32(outParams.P roperties["ReturnValu e"].Value) != 0)
...

}
}

I get a management exception error on the line " ManagementBaseO bject
outParams = dir.InvokeMetho d("Delete", null,

null);" The directory appears to be showing correctly. Does this method work with mapped drives?

Yes, it does work for mapped drives assumed you have rights to delete the
folder. How does your path string looks like and what exception do you get?

I actually used an earlier option in the thread (just making each file in the
target directory read only). Thanks for your help though. I might try to get
the code working in the future and maybe post another thread if i get stuck.

Thanks.
