The LINQ expression node type 'ArrayIndex' is not supported in LINQ to Entities

Question

public List GetpathsById(List id)
{
    long[] aa = id.ToArray();
        long x;
    List paths = new List();
         


        

Answer 1

Can be simplified to avoid the error:

public List GetpathsById(List id)
{
    return context.Presentations.Where(x => id.Contains(x.PresId)).Select(x => x.FilePath).ToList();
}
