How can I write Take(1) in query syntax

Question

Is it possible to write IQueryable<MyObject> = query.Take(1) or something equivalent in LINQ query syntax. I'm using C# 5 and EF 5.

Unfortunately no, C# doesn't have as many in-language Linq keywords as VB, but you can do it without it looking too messy by adding .Skip(n).Take(m) at the end. – Calcic

@TimSchmelter oh cool. Out of curiosity, what is the syntax in VB.NET? – Xantho

Take realized the query, it should be keep separate from the logical query. – Marsupium

@Steaks: From r In query Take 2 (skip works similar) – Goshen

In addition to Take, VB also adds Distinct, Aggregate, Count, Sum as keywords. – Cali

Query keywords - this might be helpfull – Tullis

Answer 1

There is no equivalent to Take in the query expression syntax for LINQ in C#. The only methods that have query expression equivalents are

Where,
Select,
SelectMany,
Join,
GroupJoin,
OrderBy,
OrderByDescending,
ThenBy,
ThenByDescending,
GroupBy,
Cast

This is from §7.16.2 of the specification.

I didn't know there was an Enumerable.GroupJoin! – Xantho

Answer 2

No. You have to use the dot syntax for that operation. Same goes for ToList, Count, etc...

var query =
    (from item in list
     where predicate(item)
     select func(item))
    .Take(10);
