How to use contain in linq query?

I would like to be able to query the (name) parameter such as (api/data?name=prestl,accam,bcam...(25 values). This is currently what I have and the code is throwing me the following issues:

Delegate 'System.Func<Testing_Apr.database_Bd,int,bool>' does not take 1 arguments

string' does not contain a definition for 'split' and no extension method 'split' accepting a first argument of type 'string' could be found (are you missing a using directive or an assembly reference?)

var data = db.database_Bd.AsQueryable();

            if (query.startDate != null)
            {
                data = data.Where(c => c.UploadDate >= query.startDate);
            }

            if (!string.IsNullOrEmpty(query.name))
            {
                var list = query.name.split(',');
                data = data.Where(pr => list.Any(pr2 => pr.Name.Contains(pr2)));
            }

Any advice, would be very much appreciated.
Many thanks
