In LINQ you can’t use “if” statement directly in select clause, but you can achieve this by using ternary operator. Consider you are querying an Array of object & the object internally contains another object. We have to select some field from inner object.

What is Predicatebuilder C#?
Predicate Builder is a powerful LINQ expression that is mainly used when too many search filter parameters are used for querying data by writing dynamic query expression. We can write a query like Dynamic SQL. To learn more about predicate delegate visit Predicate Delegate.

How to use multiple where condition in LINQ?
Detailed description. We have specified two where conditions in both linq and lambda queries. The first where clause checks for the income that is greater than 25,000 and the second where clause looks for the income that is less than 45,000. We can see there is just one income between 25000 and 40000.
When to use & vs.where clauses in LINQ?
I personally would always go with the && vs. two where clauses whenever it doesn’t make the statement unintelligible. In your case, it probably won’t be noticeble at all, but having 2 where clauses definitely will have a performance impact if you have a large collection, and if you use all of the results from this query.
How are multiple where clauses used in Stack Overflow?
They defer execution until the actual results are calculated (such as with a .Count () or a .ToList () ). So, as you chain together multiple methods (more calls to .Where (), maybe an .OrderBy () or something to that effect, etc.) they build up what’s called an expression tree.
What are the where conditions in lambda in LINQ?
We have specified two where conditions in both linq and lambda queries. The first where clause checks for the income that is greater than 25,000 and the second where clause looks for the income that is less than 45,000. We can see there is just one income between 25000 and 40000. So we should be getting this as output from both queries.
