I want to get all of the files in a directory in an array (including the files in subfolders)
string[] filePaths = Directory.GetFiles(@"c:\",SearchOption.AllDirectories);
The problem with this is: If an exception is thrown the entire command stops. Is there a better way to do this so that if a folder cannot be accessed it will just skip over it?
Directory.GetFiles can't skip directory symbol links which often cause loops and then exceptions.
So based on @iks's answer and Check if a file is real or a symbolic link, here is a version that deliver the result on the go like Directory.EnumerateFiles does:
public static IEnumerable<string> FindAllFiles(string rootDir)
{
var pathsToSearch = new Queue<string>();
pathsToSearch.Enqueue(rootDir);
while (pathsToSearch.Count > 0)
{
var dir = pathsToSearch.Dequeue();
var foundFiles = new List<string>();
try
{
foreach (var file in Directory.GetFiles(dir))
foundFiles.Add(file);
foreach (var subDir in Directory.GetDirectories(dir))
{
//comment this if want to follow symbolic link
//or follow them conditionally
if (IsSymbolic(subDir)) continue;
pathsToSearch.Enqueue(subDir);
}
}
catch (Exception) {//deal with exceptions here
}
foreach (var file in foundFiles) yield return file;
}
}
static private bool IsSymbolic(string path)
{
FileInfo pathInfo = new FileInfo(path);
return pathInfo.Attributes.HasFlag(System.IO.FileAttributes.ReparsePoint);
}
static public void test()
{
string root = @"D:\root";
foreach (var fn in FindAllFiles(root)
.Where(x=>
true //filter condition here
))
{
Debug.WriteLine(fn);
}
}
