Is it code first or database first?

For entity:

C#

int[] codestofind = new {100, 200}
PersonBranch[] pbs = context.PersonBranchDefine
    .Where(pbd=> pbd.BranchCodes.Any(bc=>codestofind.Contains(bc.BranchCode))
    .Select(pbd=>new PersonBranch(pbd.BranchName, pbd.BranchCode,1,0))
    .ToList();
context.PersonBranches.AddRange(pbs);
context.SaveChanges();
