given folder /a/b
let /a/b/c point to /a
then
/a/b/c/b/c/b becomes valid folder locations.

我建议像这样的策略.在Windows上,您被限制为路径字符串上的最大长度,因此递归解决方案可能不会破坏堆栈.

private void FindFilesRec(
    string newRootFolder,Predicate<FileInfo> fileMustBeProcessedP,Action<FileInfo> processFile)
{
    var rootDir = new DirectoryInfo(newRootFolder);
    foreach (var file in from f in rootDir.GetFiles()
                         where fileMustBeProcessedP(f)
                         select f)
    {
        processFile(file);
    }

    foreach (var dir in from d in rootDir.GetDirectories()
                        where (d.Attributes & FileAttributes.ReparsePoint) != FileAttributes.ReparsePoint
                        select d)
    {
        FindFilesRec(
            dir.FullName,fileMustBeProcessedP,processFile);
    }
}
