Question

I have a Listof objects that I would like to convert to a byte[]

My List is defined like this:

List<object> objects = new List<object>
{
     "obj1", "obj2", "obj2"
};

Is it possible to convert this list to a byte[] in some clean way? The list only contains base64 strings

All help is appreciated

Answer 1

Piece of cake:

objects.Select(s => Convert.FromBase64String(s)).SelectMany(i => i).ToArray();

If objects is really a List<Object> as @AustinSalonen points out, as opposed to a List<String>, you need to make sure that you only have strings first:

objects.OfType<String>().Select(s => Convert.FromBase64String(s)).SelectMany(i => i).ToArray();

or cast:

objects.Cast<String>().Select(s => Convert.FromBase64String(s)).SelectMany(i => i).ToArray();
