I have a cshtml view where the user can enter a first name, last name, or a SSN number and then do a search. They can enter any data they want in any box. The more data they enter, the more narrow the search becomes. Currently each if statement I have in my code is doing an 'or' statement; it adds extra rows to my result set if I enter information into another search box. I want it to be an "and" situation. This is what I have:



 var FilterSet = VetDb.AllPeople.AsQueryable();
if(!string.IsNullOrEmpty(FirstName))

FilterSet = FilterSet.Where(m => m.First_Name.ToLower().Contains(FirstName.ToLower()));

else if(!string.IsNullOrEmpty(LastName))

FilterSet = FilterSet.Where(m => m.Last_Name.ToLower().Contains(LastName.ToLower()));

else if (!string.IsNullOrEmpty(SSN))

FilterSet = FilterSet.Where(m => m.SSN.ToLower().Contains(SSN.ToLower()));



But I would like it to be something like this:



 var FilterSet = VetDb.AllPeople.AsQueryable();
if(!string.IsNullOrEmpty(FirstName))

FilterSet = FilterSet.Where(m => m.First_Name.ToLower().Contains(FirstName.ToLower()));

else if(!string.IsNullOrEmpty(LastName))

FilterSet = FilterSet + FilterSet.Where(m => m.Last_Name.ToLower().Contains(LastName.ToLower()));

else if (!string.IsNullOrEmpty(SSN))

FilterSet = FilterSet + FilterSet.Where(m => m.SSN.ToLower().Contains(SSN.ToLower()));



Note: I added FilterSet + to each line.



I know it is probably a simple question so any help with this would be much appreciated.



thanks
adam
