移动服务蔚蓝-不指定列值

Question

var items = await App.MobileService.GetTable<Profile>().Where(item => (item.status == status) && 
(item.genre == genre)&&(item.category == category) && (item.location == location) &&
(item.age == age)).ToListAsync();

This is my query that I am sending to my azure database to retrieve the results. Assume the user doesn't specify a location however he satisfies all other requirements. How can I retrieve all the results that are relevant to my query without specifying the location of that specific user and still be able to fetch it. Is there an any type that I can use in the query or a '*' for example.

Answer 1

如果我正确理解，则可以尝试使用

item.Location.Contains(location)

Answer 2

您是否正在寻找这样的东西？

&& (string.IsNullOrEmpty(location) || item.location == location) &&
