How to get page template files in the Site Pages library?

[mohammadamer]

First Question:
I tried to get only the files in the templates folder in site pages library, but I couldn't. I read the documentation, but I could not understand how to load the templates folder and load only the files in the templates folder.

Second Question:
Is it possible to get the hub site child sites using PnP Core SDK?

This is my code snippets:

          IFolder folder = await _ctx.Web.Folders.Where(f => f.Name == "SitePages").FirstOrDefaultAsync();
           await folder.EnsureFolderAsync("Templates");
           
           await folder.LoadAsync(p => p.Files);

           foreach (var file in folder.Files.AsRequested())
           {
               _log.LogInformation($"List item: {file.ServerRelativeUrl}"); 
           }

I tries to load SitePages IFolder then Templates as IFolder the load files in Templates folder but it returns null.

     await _ctx.Web.LoadAsync(p => p.Folders);
            IFolder folder = _ctx.Web.Folders.AsRequested().FirstOrDefault(p => p.Name == "SitePages");
            IFolder Templatefolder = folder.Folders.AsRequested().FirstOrDefault(p => p.Name == "Templates");
            await Templatefolder.LoadAsync(p => p.Files);
            foreach (var file in Templatefolder.Files.AsRequested())
            {
                _log.LogInformation($"Getting list item information {file.ServerRelativeUrl}");
            }

@mohammadamer : see my answer to your later question, you need to correctly create the Templates folder.
