asp.net - Linq to Entities does not recognize the method collection Dictionary -


i have model named emaildetailmodel dictionary field.

my query is:

var query = email in context.emailmodel             rolesforuser.contains(email.groupname)             orderby email.id descending             select new emaildetailmodel()              {                 = email.from,                 id = email.id,                 message = email.body,                 subject = email.subject,                 pathfilename =                        (from pdf in context.pdfmodel                         pdf.email_id == email.id                         select pdf)                     .todictionary(k => k.pathfile, v => v.filename),                 timesend = email.activetime};

however error occurs on line when trying send list view:

view(query.topagedlist(pagenumber, pagesize));

saying that:

linq entities not recognize method 'system.collections.generic.dictionary

if me, i'm not sure how can pass key , value pathfilename dictionary.

the issue there no sql conversion of dictionary generation linq entities can understand.

i have struggled similar error messages whenever linq cannot translated sql statement.

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.
