我的LINQ查詢是給下面的錯誤:LINQ是給錯誤:類型聯接子句中的表現之一是不正確
The type of one of the expressions in the join clause is incorrect. Type inference failed in the call to 'GroupJoin'.
我有以下的LINQ查詢這是給錯誤:
from m in array join p in resellers on m equals p.ResellerId into j
// join p in resellers on new { m } equals new { p.ResellerId } into j
變量'array'的類型是什麼? –
