关于EF中要用到in查询，查询的字段是整型！代码执行报错！在线求解，急急急！！！

public static Dictionary<int, string> GetNameByLevel2(string pids)
{
Dictionary<int, string> ret = new Dictionary<int, string>();
string[] ary = pids.Split(',');
int[] tt = new int[] { ary.Length };
for (int i=0;i<ary.Length;i++) {
tt[i] = Convert.ToInt16(ary[i]);
}
using (var db = new DB())
{

var data = db.good_Tag.Where(x => x.Level == 2 && tt.Contains(Convert.ToInt32(x.ParentID)));
ret = data.ToDictionary(it => it.ID, it => it.Name);
}
return ret;
}

linq to entities 不支持Convert转换语句，你把转换放到外边了，再添加到条件里。

已经找到问题了！谢谢

var data = db.good_Tag.Where(x => x.Level == 2 && tt.Contains(Convert.ToInt32(x.ParentID))); 错在这一句吧
