Linq ToList出错：

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;


}

------解决方法--------------------------------------------------------

C# code

public IList  GaChas()         {             IList  adr_gaCha = new List ();             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，Linq ToList出错就可以解决。

select new 生成的新类型无法转换为adr_GaCha

C# code

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;         }
