LINQ编译的查询，类别字段

我怎样才能insted的公共变种compiledQuery写Func键< MYEntities，串，???>LINQ编译的查询，类别字段

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});

当我尝试像这样我得到错误：仅参数表较少构造函数被支持

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)));

你可以试试。希望这将工作

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});

请给出您的错误 – anishMarokey 2011-05-16 07:09:01

无法初始化类型'Database.User_Services.MyUser'集合初始化程序，因为如果它不是IEnumerable类型，它不会实现'System.Collections.IEnumerable' – 2011-05-16 07:46:27
