c# 4.0 - How to access anonymous type projected in Linq query in the next chained extension method? -


i have collection of schemas, each schema has name, id , several other properties. need project name , id of every schema , creating anonymous type in linq query follows:

from s in db.schemas select new { id = s.schemaid, name = s.name}

i need convert above anonymous type projected via select query operator dictionary<int,string> , need add further extension method overload above query follows:

(from s in db.schemas select new { id = s.schemaid, name = s.name}) .todictionary<tsource,int,string>()

now, how can access anonymous type in todictionary() overload?

what should replace tsource type parameter with?

i have other methods this, wondering if can done in way accessing anonymous type. other nice method welcome.

you can elide type arguments completely.

(from s in db.schemas select new { id = s.schemaid, name = s.name})     .todictionary(p => p.id, p => p.name);

the compiler can infer them you.

in fact, may able in single step:

db.schemas.todictionary(s => s.schemaid, s => s.name);

or @ least sticking 1 type of linq syntax:

db.schemas     .select(s => new { id = s.schemaid, name = s.name })     .todictionary(p => p.id, p => p.name);

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
