如果刪除一個文件夾的內容是你想要什麼來實現這樣的遞歸方法將工作：

public static async Task DeleteFolderContentsAsync(StorageFolder folder, 
    StorageDeleteOption option) 
{ 
    // Try to delete all files 
    var files = await folder.GetFilesAsync(); 
    foreach (var file in files) 
    { 
     await file.DeleteAsync(option); 
    } 

    // Iterate through all subfolders 
    var subFolders = await folder.GetFoldersAsync(); 
    foreach (var subFolder in subFolders) 
    { 
     // Delete the contents 
     await DeleteFolderContentsAsync(subFolder, option); 

     // Delete the subfolder 
     await subFolder.DeleteAsync(option); 
    } 
}
