Question

我需要在不同目录的特定文件夹（例如CR7）中找到很多文件（图像）。想象一下，我有一个网络共享，我必须查找并显示该特定文件夹（CR7）中的所有图像。 CR7文件夹可以在不同的地方找到，例如： \\share\folder01\CR7或：\\share\folder01\folder02\CR7或其他任何内容。我所拥有的是这个，但是来自filesList的结果却没有进入datagridview：

public partial class FormProcuraFotos : Form
{
    DataTable tableWithPhotos;
    public FormProcuraFotos()
    {
        InitializeComponent();
    }
    private void button1_Click(object sender, EventArgs e)
    {
        progressBar1.Visible = true;
        BackgroundWorker worker = new BackgroundWorker();
        worker.DoWork += this.Worker_DoWork;
        worker.RunWorkerCompleted += this.Worker_RunWorkerCompleted;
        worker.RunWorkerAsync();
    }
    private void Worker_DoWork(object sender, DoWorkEventArgs e)
    {
        // Create the new DataTable to be used
        tableWithPhotos = new DataTable();
        tableWithPhotos.Columns.Add("Filenames");
        tableWithPhotos.Columns.Add("Ctrl+C");
        //Find files on a specific folder (CR7)
        string allDir = @"\\server\folder01";
        var CR7Directories = Directory.EnumerateDirectories(allDir, "CR7", SearchOption.AllDirectories);
        List<string> extensions = new List<string>() { ".jpg", ".bmp", ".png", ".tiff", ".gif" };
        List<string> filesList = new List<string>();
        foreach (var dir in CR7Directories)
        {
            List<string> FileNames = new DirectoryInfo(dir).EnumerateFiles(dir)
                                                           .Where(x => extensions.Contains(x.Extension))
                                                           .Select(x => x.Name).ToList();
            filesList.AddRange(FileNames);
        }
        // And now here we will add all the files that it has found into the DataTable
        foreach (string entryFiles in filesList)
        {
            DataRow row = tableWithPhotos.NewRow();
            row[0] = Path.GetFileName(entryFiles);
            row[1] = entryFiles;
            tableWithPhotos.Rows.Add(row);
        }
    }
    private void Worker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
    {
        progressBar1.Visible = false;
        var formToOpen = new FormResultadosFotos(tableWithPhotos);
        formToOpen.Show();
    }
}

我认为您必须按以下步骤划分执行范围：

通过将"CR7"指定为"CR7"，获得指定文件夹下名称为searchPattern的所有目录。
现在您已经拥有所有CR7文件夹路径，遍历每个CR7目录中的那些集合并获取文件列表并根据扩展名列表对其进行过滤。

您可以尝试一下，让我知道它是否解决了您的问题：

string allDir = @"\\share\folder01";
var CR7Directories = Directory.EnumerateDirectories(allDir, "CR7", SearchOption.AllDirectories);
List<string> extensions = new List<string>() { ".jpg", ".bmp", ".png", ".tiff", ".gif" };
List<string> filesList = new List<string>();
foreach (var dir in CR7Directories)
{
    List<string> FileNames = new DirectoryInfo(dir).EnumerateFiles(dir)
                                                   .Where(x => extensions.Contains(x.Extension))
                                                   .Select(x => x.Name).ToList();
    filesList.AddRange(FileNames);
}
