Lambda LINQ is still a link expression. However, the statement should look something like this: var train2 = (from c in db.sample1 join t in db.sample2 on c.CertificateId equals t.CertificateId where c.Year.Value.Year == year && c.TrainingTypeId.Value == trainingTypeId && c.IsApproved.Value && t.EndDate >= DateTime.Now select c).Distinct(); 8 solved Lambda convert to LINQ

[Solved] How do I sort a text file by three columns with a specific order to those columns in Python?

by

So the index here is probably off by one, but I think you get the concept: #read lines of text file and split into words lines = [line.split() for line in open(“test.txt”, “r”)] #sort lines for different columns, … Read more

[Solved] Sort date using lambda expression [closed]

What you’re ordering by here is the distance between the pivot (the birthdate) and each date. Something like this: var sorted = data.OrderBy(date => (birthdate – date).TotalDays); will sort by distance, but put all the after dates first, because the TotalDays will be negative, then the before dates. To avoid that, we need to implement … Read more
