在不同目錄的特定文件夾中查找文件

Question

我需要在不同目錄的特定文件夾（例如 CR7）中找到很多文件（圖像）。 想象一下，我有一個網絡共享，我必須在該特定文件夾 (CR7) 中查找和顯示所有圖像。 CR7 文件夾可以在不同的地方找到，例如： \\\\share\\folder01\\CR7或： \\\\share\\folder01\\folder02\\CR7或其他任何地方。 我所擁有的是這個，但是來自filesList結果不會轉到 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();
    }
}

Answer 1

我認為您必須通過以下步驟拆分執行：

• 通過將"CR7"指定為searchPattern來獲取指定文件夾下名稱為"CR7"所有目錄。
• 現在您擁有所有 CR7 文件夾路徑，遍歷這些集合並獲取文件列表，並根據每個 CR7 目錄中的擴展名列表過濾它們。

你能試試這個嗎，讓我知道它是否解決了你的問題：

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);
}
