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.
LINQ query syntax is consist of a set of query keywords defined into the . NET Framework version 3.5 or Higher. This allows the programmer or developers to write the commands similar to SQL style in the code(C# or VB.NET) without using quotes. It is also know as the Query Expression Syntax.
Use the OrderByDesecnding() amd First() query operators. No - LINQ to SQL does the optimization of doing everything on the server side and getting you only one record. Great! That works, it produces a nice "select top 1" T-SQL.
There are the following two ways to write LINQ queries using the Standard Query operators, in other words Select, From, Where, Orderby, Join, Groupby and many more. Using lambda expressions. Using SQL like query expressions.
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.
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);
