Querying between two date values in asp.net mvc5 -


i have treatmentdate column in database dates treated patients submitted. if need generate report of total sum between january 01 2015 , jan 30 2015 particular company, how construct query.

below have done , i'm having errors

            var treatmentsum = (from s in db.treatments                                 (s.companyid == companyid)                                 s.treatmentdate >= fromdate && s.treatmentdate <= todate                                 select s.amount).sum();                             viewbag.treatmentsum = treatmentsum;

here's treatment date column want search through. enter image description here

your guidance highly appreciated.

you didn't post error message. trying compare strings using <= , >= , instead try handle of date , time variable datetime properties. here's piece of code linq expression:

datetime fromdate= convert.todatetime("04/20/2015"); datetime todate= convert.todatetime("04/28/2015"); viewbag.treatmentsum = getalltreatments. where(c=>convert.todatetime(c.treatmentdate)>=fromdate && convert.todatetime(c.treatmentdate)<=todate). sum(c=>c.amount);

also here's link demo specific problem : https://dotnetfiddle.net/1a50hi

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.
