在不同目录的特定文件夹中查找文件

Question

I need to find a lot of files (images) in a specific folder (for exemple CR7), in different directories. Imagine I have a network share that I have to find and display all images in that specific folder (CR7). CR7 folder can be found in different places like: \\\\share\\folder01\\CR7 or: \\\\share\\folder01\\folder02\\CR7 or anything else. What I have is this, but results from filesList dont go to 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();
    }
}

I think you have to split the execution by following steps:

• Get all Directories with name "CR7" under the specified folder by specifying "CR7" as searchPattern .
• Now you have all CR7 folder paths, Iterate through those collection and Get List of files and filter them based on the extension list, in each CR7 directory.

Can you please try this and let me know whether it solved your issues:

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);
}
