entity framework - Access value generated by trigger after save changes - 


        var school = new models.school();          schoolcommandtoschool.map(school, model);          _schoolrepository.add(school);          _unitofwork.savechanges();          school.code // null

after insert generate school code inside trigger , store in code column. after save changes null.

entity didn't know fetch data column if wrote data inside insert trigger?

can explain what's happening?

you can use changetracker, track changes in object. this:

inside dbcontext class (not tested code):

public override int savechanges() {     //detect changes     this.changetracker.detectchanges();     //get schools object, if exists     //you can check if object being insert or updated     // => i.state == entitystate.modified or entitystate.added     var entries = this.changetracker.entries().where(i => i.entity.gettype() == typeof(school);      if (entries.any())     {         foreach (var entry in entries) {             //do trigger job in entry object;         }     }       return base.savechanges(); }

everytime change school run additional code.

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.
