linq 编译查询，类字段

Question

我如何插入 public var CompiledQuery 编写 Func MYEntities,string, ???>

    public var compiledQuery = CompiledQuery.Compile((AddresEntities ctx, string name) =>
    from x in ctx.User
    where x.Name.Contains(name)
    select new { x.Name, x.Phone});

当我这样尝试时，我收到错误： 仅支持无参数构造函数

 public static   Func<AddresEntities, string, IQueryable<MYClass>> compiledQuery =
           CompiledQuery.Compile((AddresEntities ctx, string name) =>
                                 (from x in ctx.Users
                                  where x.Name.Contains(name)
                                   select new MYkontakt( x.Name, x.Phone)));

你可以尝试。希望这会起作用

IEnumerable<yourType> compiledQuery = CompiledQuery.Compile((AddresEntities ctx, string name) =>
from x in ctx.User
where x.Name.Contains(name)
select new yourType { x.Name, x.Phone});
