linq - How can I modify this C# code so that Visual Studio recognizes that I'm not an idiot? -


i have 3 lines go

int selectedorgid;   foreach (organization o in pd.orgs)     if (o.orgname == selectedorgname)          selectedorgid = o.orgid;  pd.cats.insertonsubmit(new category {     orgid = selectedorgid,     catname = newcatname });

the middle line, loop, guaranteed, in context of program, set value selectedorgid. however, visual studio flagging last line because

use of unassigned local variable 'selectedorgid'

what way solve other 

int selectedorgid = 69;   foreach (organization o in pd.orgs)     if (o.orgname == selectedorgname)          selectedorgid = o.orgid;  pd.cats.insertonsubmit(new category {     orgid = selectedorgid,     catname = newcatname });

????

although works, seems inelegant solution, since involves magic number. want know proper c# style of solving this.

edit:

looking @ of discussion here, should've specified there such orgid in database. foreach statement should've been written like

foreach (organization o in pd.orgs) {     if (o.orgname == selectedorgname)     {          selectedorgid = o.orgid;          break;     }  }

thanks showing me ways better whole thing!

it appears you're iterating through collection, trying find single matching value based on organization name. can use linq's singleordefault() find (at most) 1 match:

var selectedorg = pd.orgs.singleordefault(o => o.orgname == selectedorgname);

then call insertonsubmit() if value found: (otherwise, selectedorg null)

if (selectedorg != null)     pd.cats.insertonsubmit(new category { orgid = selectedorg.orgid, catname = newcatname });

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.
