我正在填充Viewmodel，并尝试获取该记录的CurrencyIds和CurrencyNames，并将其存储在viewmodel的属性中。我正在获取CurrenctIds，但如何获取CurrencyNames。
当前它仅返回一个值。如何查询OtherCurrencyIds并检索值
var currencyLookUp = currencies.Select(x => new LookUpViewModel()
{
Id = x.CURRENCY_ID,
Name = x.CURRENCY_NAME
});
var legalFundClassDetailsViewModel = legalfundClasses.Select(fc => new LegalFundClassDetailsViewModel
{
OtherCurrencyIds = otherCurrencies
.Where(x => x.FUND_CLASS_ID == fc.ID)
.Select(x => x.CURRENCY_ID)
.ToArray(),
OtherCurrencyNames = currencyLookUp
.Where(x => x.Id == fc.CURRENCY_ID)
.Select(x => x.Name)
.ToArray()
});

您可以使用匿名类型：
var currencyLookUp = currencies.Select(x => new
{
Id = x.CURRENCY_ID,
Name = x.CURRENCY_NAME
});
然后
var legalFundClassDetailsViewModel = legalfundClasses.Select(...).Distinct();

我认为最简单的方法是在select语句内使用货币ID创建一个临时变量。
var currencyLookUp = currencies.Select(x => new LookUpViewModel()
{
Id = x.CURRENCY_ID,
Name = x.CURRENCY_NAME
}).ToList(); // Note I materialized the currencies here.
var legalFundClassDetailsViewModel = legalfundClasses.Select(fc =>
{
// temp variable
var ids = otherCurrencies
.Where(x => x.FUND_CLASS_ID == fc.ID)
.Select(x => x.CURRENCY_ID)
.ToArray();
return new LegalFundClassDetailsViewModel
{
OtherCurrencyIds = ids,
// Query the currency lookup based on the temp variable.
OtherCurrencyNames = ids.Select(
id => currencyLookUp.FirstOrDefault(l => l.Id == id)?.Name)
.ToArray()
});
});
