If you want to continue with the next folder after a fail, then yea; you'll have to do it yourself. I would recommend a Stack (depth first) or Queue (bredth first) rather than recursion, and an iterator block (yield return); then you avoid both stack-overflow and memory usage issues.
public static IEnumerable<string> GetFiles(string root, string searchPattern)
{
Stack<string> pending = new Stack<string>();
pending.Push(root);
while (pending.Count != 0)
{
var path = pending.Pop();
string[] next = null;
try
{
next = Directory.GetFiles(path, searchPattern);
}
catch { }
if(next != null && next.Length != 0)
foreach (var file in next) yield return file;
try
{
next = Directory.GetDirectories(path);
foreach (var subdir in next) pending.Push(subdir);
}
catch { }
}
}
Or You can do as below:
You can set the program so you can only run as administrator.
In Visual Studio:
Right click on the Project -> Properties -> Security -> Enable
ClickOnce Security Settings
After you clicked it, a file will be created under the Project's properties folder called app.manifest once this is created, you can uncheck the Enable ClickOnce Security Settings option
Open that file and change this line :
<requestedExecutionLevel level="asInvoker" uiAccess="false" />
to:
<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
This will make the program require administrator privileges, and it will guarantee you have access to that folder.
