EF Core:无法翻译LINQ表达式-Net Core 3.1

Question

我正在尝试实现一个查询，以查找每个站点中与分配用户条件匹配的所有条件，并将其删除，不包括不匹配的条件。

var savedPartnerConditions = eipDbContext.EIP_User_Partner_Condition.Where(savedCondition => savedCondition.EIP_User_Partner_Id == savedPartner.EIP_User_Partner_Id && existingUser.CurrentUserConditions.Any(condition => condition.Code == savedCondition.Code));
eipDbContext.EIP_User_Partner_Condition.RemoveRange(savedPartnerConditions);

但是查询无法翻译，导致以下错误：

.Any(condition => condition.Code == e.Code))' could not be translated. Either rewrite the query in a form that can be translated, or switch to client evaluation explicitly by inserting a call to either AsEnumerable(), AsAsyncEnumerable(), ToList(), or ToListAsync()

如何构造查询以修复错误？

我用以下代码修复了这个问题，这些代码似乎有效：

var selectionResultSet = eipDbContext2.EIP_User_Partner_Condition.Where(savedCondition => savedCondition.EIP_User_Partner_Id == savedPartner.EIP_User_Partner_Id).ToList();
var savedPartnerConditions = selectionResultSet
.AsEnumerable()
.Where (savedCondition => (existingUser.CurrentUserConditions.Any(condition => condition.Code == savedCondition.Code)));
eipDbContext3.EIP_User_Partner_Condition.RemoveRange(savedPartnerConditions);
