[英]Check if string does not contain strings of an array of string in C# in query from Entity Framework
I tried to get a special count where I want to remove results where the userKeysActionsArray is a string that contains integer like this way (JSON array): [88254,8547,8569]我试图获得一个特殊的计数,我想删除其中 userKeysActionsArray 是一个包含 integer 的字符串的结果,就像这样(JSON 数组):[88254,8547,8569]
But when I tried to remove with a contains method and the NOT operator, I couldn't get the right number I expected.但是当我尝试使用 contains 方法和 NOT 运算符删除时,我无法获得我期望的正确数字。
I don't know how to resolve this problem.我不知道如何解决这个问题。
Thanks a lot for your help.非常感谢你的帮助。
int count;
var query = (from a in _db.ApplicationSet
from h in a.ApplicationApprobationStatusHistorySet
from u in a.Mission.MissionUserSet
where a.Mission.isDeleted == false
&& a.Mission.isArchived == false
&& a.isRefused == false
&& a.ApplicationApprobationStatus.shortCode == "APPLICATION_APPROBATION_STATUS_LM_WAITING"
&& u.userKey == ContextUser.id
&& h.ApplicationApprobationStatus.shortCode == "APPLICATION_APPROBATION_STATUS_LM_WAITING" && h.isDeleted == false
orderby a.applicationDate
select new ApplicationCandidateListing
{
applicationKey = a.id,
missionKey = a.Mission.id,
candidateKey = a.Candidate.id,
statusKey = a.ApplicationStatus.id,
clientKey = a.Mission.Client.id,
candidateFirstName = a.Candidate.firstName,
candidateLastName = a.Candidate.lastName,
clientLabel = a.Mission.Client.name,
statusLabel = a.ApplicationStatus.label,
missionLabel = a.Mission.label,
applicationDate = a.applicationDate,
isCVreserveList = a.isCVreserveList,
isCVviewed = a.isCVviewed,
refuseDate = a.refuseDate,
isShortListed = a.isShortListed,
candidateGroupShortcode = a.Candidate.CandidateGroup.shortCode,
approbationStatusIcons = a.ApplicationApprobationStatus.iconCSS,
approbationStatusShortCode = a.ApplicationApprobationStatus.shortCode,
isInternal = a.Candidate.isInternal,
lineManagerKey = ContextUser.id,
userKeysActionsArray = h.userKeysActionsArray,
commentCount = a.ApplicationCommentSet.Where(ac => ac.isPrivateLineManager != true).Count()
}).Distinct();
string chance1 = "[" + ContextUser.id.ToString() + "]";
string chance2 = "[" + ContextUser.id.ToString() + ",";
string chance3 = "," + ContextUser.id.ToString() + ",";
string chance4 = "," + ContextUser.id.ToString() + "]";
var values = new[] { chance1, chance2, chance3, chance4 };
query.Where(q => !(values.Any(q.userKeysActionsArray.Contains)));
count = query.Count();
return count;
You can accumulate where conditions on the query in a foreach:您可以在 foreach 中累积查询条件:
var query = // redacted
string chance1 = "[" + ContextUser.id.ToString() + "]";
string chance2 = "[" + ContextUser.id.ToString() + ",";
string chance3 = "," + ContextUser.id.ToString() + ",";
string chance4 = "," + ContextUser.id.ToString() + "]";
var values = new[] { chance1, chance2, chance3, chance4 };
foreach(var value in values)
{
query = query.Where(a => !a.userKeysActionsArray?.Contains(value) ?? true);
}
return query.Count();
You can do it as below -你可以这样做 -
query.Where(q => !(
(q.userKeysActionsArray.Contains(chance1) ||
q.userKeysActionsArray.Contains(chance2) ||
q.userKeysActionsArray.Contains(chance3) ||
q.userKeysActionsArray.Contains(chance4))));
