I want to get a list of string based in two lists lstJobs and lstPraudits. I want to get PlanId which is common in both list.
Here is my code-
List<string> result=reviewModel.lstJobs.Select(x=>x.planId.Contains(reviewModel.lstPraudits.Slect(y=>y.PlanId).toList()));
What I am doing wrong here. Code is giving error message.
Use Enumerable.Intersect:
List<string> result = reviewModel.lstJobs.Select(x=> x.PlanId)
.Intersect(reviewModel.lstPraudits.Select(y=> y.PlanId))
.ToList();
What I am doing wrong here
Your approach is wrong because x.planId.Contains will search substrings and you are passing a list to the method. It's the wrong approach anyway because you don't want to compare substrings.
Using Intersect is a nice approach.. But if you say what you are doing wrong I would say you are iterating on the wrong thing. The query as per your appproach should be:
List<string> result = reviewModel.lstJobs.Select(x => reviewModel.lstPraudits.Select(y=>y.PlanId).Contains(x.planId))
Use Where to compare between both List.
List<string> result =
reviewModel.Where(x => x.planId.Contains(reviewModel.lstPraudits.Select(y=>y.PlanId)))
.ToList();
SlectandtoListunless you have defined these methods yourself.
