遍历文件和文件夹，并用滚动条显示进度和写入错误日志

private void getSome(DirectoryInfo dir)
        {
            progressBar1.Minimum = 1;    //设置滚动条的最小值
            
            FileSystemInfo[] file = dir.GetFileSystemInfos();    //获取文件夹内所有文件和文件夹
            progressBar1.Maximum = file.Length;                  
            foreach (FileSystemInfo fi in file)
            {
                if (fi is DirectoryInfo)
                {
                    string directory = dir.FullName + @"\" + fi.Name;
                    try
                    {
                        DirectoryInfo info = new DirectoryInfo(directory);
                        info.Delete(true);
                        getSome(info);
                    }
                    catch
                    {
                        string path = Application.StartupPath + @"\" + "error.log";
                        StreamWriter w = new StreamWriter(path, true, Encoding.UTF8);
                        FileInfo f = new FileInfo(path);
                        if (f.Exists)
                        {
                            w.WriteLine("文件:" + directory + "    不能被删除");
                            w.Close();
                        }
                        else
                        {
                            File.Create(path);
                        }
                        continue;
 
                    }
                }
                else
                {
                    string filename = dir.FullName + @"\" + fi.Name;
                    try
                    {
                        label1.Text = filename;
                        //File.Delete(filename);
                        progressBar1.PerformStep();
                        Thread.Sleep(100);
                    }
                    catch
                    {
                        string path = Application.StartupPath + @"\" + "error.log";
                        StreamWriter w = new StreamWriter(path, true, Encoding.UTF8);
                        FileInfo f = new FileInfo(path);
                        if (f.Exists)
                        {
                            w.WriteLine("文件:" + filename + "    不能被删除");
                            w.Close();
                        }
                        else
                        {
                            File.Create(path);
                        }
                        continue;
                    }
                }
            }
        }

 

     这个方法主要是遍历所选文件夹下所有的文件和文件夹，最好使用线程启动，不然文件多的话可能出现假死的状态。

希望对大家有所帮助，我是新手，但我还是会把我每天做的东西写上来的。希望能够慢慢的提高自己的水平。现在工作可不好找。
