c# - Where should I put this using statement? -


i'm working system.directoryservices , have following method use create directoryentry:

static directoryentry createdirectoryentry(string connectionpath) {     directoryentry ldapconnection = null;      try     {         ldapconnection = new directoryentry(ad_domain_name))         ldapconnection.path = connectionpath;         ldapconnection.authenticationtype = authenticationtypes.secure;     }      catch (exception ex)     {         messagebox.show("exception caught in createdirectoryentry():\n\n" + ex.tostring());     }      return ldapconnection; }

this method called in manner:

directoryentry ldapconnection = createdirectoryentry("ldap://ou=example,dc=domain,dc=com");

i read best practice use using statement implements idisposable. question is, need using statement in createdirectoryentry() method or should each call?

to illustrate mean, sufficient?:

static directoryentry createdirectoryentry(string connectionpath) {     directoryentry ldapconnection = null;      try     {         using (ldapconnection = new directoryentry(ad_domain_name))         {             ldapconnection.path = connectionpath;             ldapconnection.authenticationtype = authenticationtypes.secure;         }     }      catch (exception ex)     {         messagebox.show("exception caught in createdirectoryentry():\n\n" + ex.tostring());     }      return ldapconnection; }

or need use using statement on call this?:

using (directoryentry ldapconnection = createdirectoryentry("ldap://ou=example,dc=domain,dc=com")) {     //do ldapconnection }

any appreciated!

note: can't use system.directoryservices.accountmanagement solution please keep answers related system.directoryservices. thanks!

your last code-snippet way go, otherwise you'd returning disposed ldapconnection caller - not thing.

and +1 using using!!

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.
