string element lenght in List<>

Question

Hi,

 

Is there an elegant way maybe LINQ to return True if all string element in a List is equal lenght? Or has a substring?

 

I was doing this way:

 

bool sha_ready = false;
            while (!sha_ready)
            {
                foreach (var item in Directory.GetFiles(destination_path, "*.wav"))
                {
                    if (!Path.GetFileName(item).ToLower().Contains("sha"))
                    {
                        sha_ready = false;
                    }
                    else
                    {

                    }
                }
            }

 

 

Thanks,
