c# - Convert simple SelectMany into query syntax -

the following simple form of selectmany(). how if @ can convert query syntax?

var array = new string[] { "shaun", "luttin" }; array     .selectmany(         s => s     ); 

the best can produces same output introduces new variable c...

var query =      s in array.asqueryable()     c in s     select c; 

...and results in following fluent syntax.

array    .selectmany (       s => s,        (s, c) => c    ); 

re: possible duplication

i have read answers is there c# linq syntax queryable.selectmany() method? i'm afraid answers' translation's not compile original fluent syntax.

the compiler performs translation turn query syntax method syntax. details specified in section 7.6.12 of c# 5 spec. quick search turns couple translations can result in call selectmany, in section 7.6.12.4:

a query expression second clause followed select clause:
x1 in e1
x2 in e2
select v
translated ( e1 ) . selectmany( x1 => e2 , ( x1 , x2 ) => v )

and

a query expression second clause followed other select clause:
x1 in e1
x2 in e2
…
translated into
from * in ( e1 ) . selectmany( x1 => e2 , ( x1 , x2 ) => new { x1 , x2 } ) …

so there appears no translation results in other overload of selectmany being called.
