c# - Should I use a using statement/dispose if the object isn't actually going to be used in code? -


this question has answer here:

i'm working in winforms code right now, , have come across lines several times:

... system.diagnostics.process.start(somefilename); ...

...which kicks off process on client machine, , forgets it. process.start(somefilename) returns process type object, implements idisposable, code not doing object, because whole idea trigger process , forget it.

in case, should process object still disposed, if we're not keeping in memory @ all? like:

using (system.diagnostics.process.start(somefilename) { }

or 

var process = system.diagnostics.process.start(somefilename); process.dispose();

process objects holds unmanaged resource(s) (hprocess handle)

https://referencesource.microsoft.com/#system/services/monitoring/system/diagnosticts/process.cs,f8b2e604d6f1fe04

public class process : component {     //     // fields     //      bool haveprocessid;     int processid;     bool haveprocesshandle;     safeprocesshandle m_processhandle; // <- should disposed     bool isremotemachine;     string machinename;     processinfo processinfo;     int32 m_processaccess; ...

and should disposed. using local variable (var process = ...) looks overshooting in context, that's why suggest

system.diagnostics.process.start(somefilename).close();

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
