Question

I have some code which ignores a specific exception.

try {     foreach (FileInfo fi in di.GetFiles())     {         collection.Add(fi.Name);     }     foreach (DirectoryInfo d in di.GetDirectories())     {         populateItems(collection, d);     } } catch (UnauthorizedAccessException ex) {    //ignore and move onto next directory } 

of course this results in a compile time warning as ex is unused. Is there some standard accept noop which should be used to remove this warning?

Answer 1

Just rewrite it as

catch (UnauthorizedAccessException) {}
