找到重复的文件 [英] find duplicated files

问题描述

嗨每一个



i我正在尝试制作找到目录中所有重复文件的项目



第一步我想得到这个目录及其子目录中的所有文件



所以我试过这段代码

hi every one

i am trying to make project that find all duplicated files in directory

first step i want to get all files in this directory and its subdirectories

so i tried this code

List<string> enumeratedFiles = Directory.EnumerateFiles(@"d:\", "*.*", SearchOption.AllDirectories)
                .Where(str => str.Contains(".")).AsParallel().ToList();

但我收到此错误

访问路径'd：\ System Volume Information \\ \\'被拒绝。



i知道我无法访问此目录

但是有没有办法跳过这个目录并继续





感谢所有

but i get this error
Access to the path 'd:\System Volume Information\' is denied.

i Know that i can't Access to this directory
but is there and way to skip this directory and continue


thanks for all

推荐答案

我知道没有内置功能来处理访问被拒绝的异常。你必须手动进行递归。

可以找到一个很好的例子http://stackoverflow.com/questions/172544/ignore-folders-files-when-directory-getfiles-is-denied -access：

As I know there is no built-in feature to handle access denied exceptions. You will have to do the recursion manually.
A good example can be found http://stackoverflow.com/questions/172544/ignore-folders-files-when-directory-getfiles-is-denied-access:

using System;
using System.IO;
static class Program
{
    static void Main()
    {
        string path = ""; // TODO
        ApplyAllFiles(path, ProcessFile);
    }
    static void ProcessFile(string path) {/* ... */}
    static void ApplyAllFiles(string folder, Action<string> fileAction)
    {
        foreach (string file in Directory.GetFiles(folder))
        {
            fileAction(file);
        }
        foreach (string subDir in Directory.GetDirectories(folder))
        {
            try
            {
                ApplyAllFiles(subDir, fileAction);
            }
            catch
            {
                // swallow, log, whatever
            }
        }
    }
}

您必须对其进行优化以匹配您的过滤。

You will have to refine this to match your filtering.
