Question

Lambda表达式中 select 怎么动态添加查询字段

Answer 1

使用 LINQ 查询表达式
IEnumerable stores =
from store in database.Stores
where store.CompanyID == curCompany.ID
select new SelectListItem { Value = store.Name, Text = store.ID };

ViewBag.storeSelector = stores;

或使用 LINQ 扩展 lambda 表达式
IEnumerable stores = database.Stores
.Where(store => store.CompanyID == curCompany.ID)
.Select(store => new SelectListItem { Value = store.Name, Text = store.ID });

ViewBag.storeSelector = stores;
