我需要周圍oldLinkers.GetNewestLinkerByCategory(mm_catalogitemcategory.Acclaim, service)?.Expire(service);
創建一個布爾值,並將其設置爲true,如果oldLinkers.GetNewestLinkerByCategory(mm_catalogitemcategory.Acclaim, service) is not null
如何創建布爾?
任何意見,如何做到這一點的布爾?下面是我的代碼?
public static void HandleLinkersForUpgrade(List<CatalogItemToOrganisationLinker> latestLinkers, List<CatalogItemToOrganisationLinker> oldLinkers, Account account, Invoice invoice, IOrganizationService service)
{
var newSupplierLinker = latestLinkers.GetNewestLinkerByCategory(mm_catalogitemcategory.Supplier, service);
var oldSupplierLinker = oldLinkers.GetNewestLinkerByCategory(mm_catalogitemcategory.Supplier, service);
var newSupplierLevel = newSupplierLinker?.ToTargetLevel(service);
var oldSupplierLevel = oldSupplierLinker?.ToTargetLevel(service);
if (newSupplierLevel > oldSupplierLevel)
{
//create the bool around line below
oldLinkers.GetNewestLinkerByCategory(mm_catalogitemcategory.Acclaim, service)?.Expire(service);
oldLinkers.GetNewestLinkerByCategory(mm_catalogitemcategory.DTS, service)?.Expire(service);
oldSupplierLinker.Expire(service);
}
var oldBuyerLinker = oldLinkers.GetNewestLinkerByCategory(mm_catalogitemcategory.Buyer, service);
var newBuyerLinker = latestLinkers.GetNewestLinkerByCategory(mm_catalogitemcategory.Buyer, service);
if (oldBuyerLinker != null && newBuyerLinker != null)
{
oldBuyerLinker.Expire(service);
}
foreach (var catItemLinker in latestLinkers)
{
if (catItemLinker.Category(service) == mm_catalogitemcategory.Acclaim)
{
UpgradeLogic.AcclaimUpgradeLogic(account, service);
}
if (oldSupplierLevel == 3)
{
var l3Linker = service.GetSetSectionToOrgLinker(account.Id, "L3");
if (l3Linker?.SectionStatus == mm_status.Verified && catItemLinker.ToTargetLevel(service) == 4) // Hack to get OAR workflows to run
{
l3Linker.SectionStatus = mm_status.AwaitingVerification;
l3Linker.Update(service);
l3Linker.SectionStatus = mm_status.Verified;
l3Linker.Update(service);
}
}
catItemLinker.MakeLive(invoice, service);
}
if (newSupplierLinker != null)
{
newSupplierLinker.TopAchievedCertificate = oldSupplierLinker?.TopAchievedCertificate;
newSupplierLinker.Update(service);
}
}
好嗎?所以做一個布爾值,如果它不爲null,則將其設置爲false。也許我誤解了你的問題,但這非常簡單。如果你無法弄清楚,那麼選擇一個基本的教程,因爲如果是這樣的話,你錯過了一些非常基礎的東西。 – tnw
不確定你的意思是「創建一個布爾」。你問如何創建布爾變量?像'var isOldLinkersNull = false;'? – bnem
@bnem我的朋友說,如果oldLinkers.GetNewestLinkerByCategory(mm_catalogitemcategory.Acclaim,service)不爲null,則將其設置爲true,然後將其傳遞給讚譽升級邏輯 ,然後只調用複製表單的部分(如果bool爲假) –
