Is there a cleaner way to write null propagation in the earlier version of C#? -


i have class.

class property {     public int? propertyid { get; set; } }

i have following statement wrote in c# 6.0

property p = null; var id = p?.propertyid.getvalueordefault() ?? 0;

turns out null propagation doesn't work in c# 5.0. rewrote as:

int id = 0; if (propertybyaddress != null && propertybyaddress.propertyid != null) {     id = p.propertyid.value; }

it seems unnecessarily wordy. there cleaner way in c# 5.0?

you can still use getvalueordefault in c# 5.0, yes null check necessary.

int id = 0; property p = null;  if (p != null)     id = p.propertyid.getvalueordefault();

you make extension method pointed out camilo, if feel that's "cleaner".

propertyextensions.cs

public static int getpropertyidvalueordefault(this property p) {     if (p != null)         return p.propertyid.getvalueordefault();      return 0; }

usage:

property p = null; var id = p.getpropertyidvalueordefault();

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...
