    {
    MasterModel _Mstr = new MasterModel();
    InsertDocs ins = new InsertDocs();
    _Mstr.Date = _inputMstr.DocDate;
    .
    .
    .

    _Mstr.DtlsModel = new List<DtlDataModel>();
            _inputMstr.MyDtlDataModel.ToList().ForEach(d =>
            {
                _Mstr.DtlsModel.Add(new DtlDataModel()
                {
                    Serial = d.Serial.ToString(),

As @BenRobinson mentioned up above, you can't do it with LINQ. LIN Q is for Q ueries. You could look at Entity Framework (or another ORM) for doing Updates, Inserts, or Deletes.

EntityFramework would look something like:

var details=new details {...}
db.details.Add(details):
db.docs.Add(new doc {... , details=details});
db.docs.Add(new doc {... , detials=details});
db.SaveChanges();
