c# - What is the best way to create a Utility dll that can be configured by consuming application? -


i have created dll has functionality in shared project project. however, may need adjust settings of dll project referencing it. best way expose configuration settings dll used project in entirely different solution?

ways have tried:

appsettings import

applicationsettings import

current setup, consuming solution setting values ignored/not set, why?

dll setting

public class applicationsettingsretriever : iapplicationsettingsretriever {     public string logenvironmentsetting => configurationmanager.appsettings.get("logenvironment"); }

consumer solution app.config

<?xml version="1.0" encoding="utf-8"?> <configuration>   <runtime>     <assemblybinding xmlns="urn:schemas-microsoft-com:asm.v1">       <dependentassembly>         <assemblyidentity name="newtonsoft.json" publickeytoken="30ad4fe6b2a6aeed" culture="neutral" />         <bindingredirect oldversion="0.0.0.0-9.0.0.0" newversion="9.0.0.0" />       </dependentassembly>     </assemblybinding>   </runtime>   <appsettings>    <add key="logenvironment" value="local"/>   </appsettings> </configuration>

you don't need import anything. in .net, dll obtains configuration settings parent application, not own config. example if need dll read connection string parent application's configuration, can use

return configurationmanager.appsettings["connectionstring"];

this read custom configuration section in app.config containing windows application, or web.config if it's web application.

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

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
