子句中的动态Linq查询

Question

I have list of Customer in List<Customer> customerList When I am using IsIn in dynamic query it gives me error : "No applicable method 'IsIn' exists in type 'CityCategory'"

customerList.AsQueryable().Where("CityCategory.IsIn(\"Metro\",\"A\")").ToList()

If I execute this query without dynamic linq it's run

customerList.Where(x => x.CityCategory.IsIn(new object[] { "Metro", "A" }));

Please tell me which method I have to use in dynamic linq string query.

Answer 1

like this:

var myList = new object[] { "Metro", "A" };

var result = customerList.Where(x => myList.Contains(x.CityCategory));

Contains will act as a in operator.
