应为 "By"

已经指定 Order By 或 Group By 子句，但其中没有 By 关键字。

错误 ID： BC36605

更正此错误

1. 将 By 关键字添加到 Order By 或 Group By 子句中。 以下是一个示例：

Dim customersByCountry = From cust In customers _  
                         Order By cust.Country, cust.City _  
                         Group By CountryName = cust.Country _  
                         Into RegionalCustomers = Group, Count() _  
                         Order By CountryName
