Linq 问题 ToList()怎么出错了

[sisiz]

public IList<adr_GaCha> GaChas()
{
IList<adr_GaCha> adr_gaCha = new List<adr_GaCha>();
var query = from c in dc.adr_GaChas select new { c.adr_GaCha_ID, c.adr_GaCha_Name };
adr_gaCha = query.ToList();//出错行
return adr_gaCha;


}

public IList <adr_GaCha> GaChas() 
        { 
            IList <adr_GaCha> adr_gaCha = new List <adr_GaCha>(); 
            var query = from c in dc.adr_GaChas select new adr_GaCha {
adr_GaCha_ID = c.adr_GaCha_ID, adr_GaCha_Name = c.adr_GaCha_Name }; 
            adr_gaCha = query.ToList();
            return adr_gaCha;          
        }

按这段代码改一下就应该可以了。

select new 生成的新类型无法转换为adr_GaCha

public IList <adr_GaCha> GaChas() 
        { 
            IList <adr_GaCha> adr_gaCha = new List <adr_GaCha>(); 
            var query = from c in dc.adr_GaChas select c; 
            adr_gaCha = query.ToList();//出错行 
            return adr_gaCha; 
        }
