LINQ lambda expression append OR statement

Question

If I want to append a AND statement to my query, I can do:

query = query.Where(obj=>obj.Id == id);

if(name.HasValue)
  query = query.Where(obj=>obj.Na         


        

Answer 1

I would just build this into a single condition:

if (name.HasValue)
    query = query.Where(obj=>obj.Id == id && obj.Name == name);
else
    query = query.Where(obj=>obj.Id == id);
