c# - Can I build 2 IServiceProvider and they work together (.net core ) - 


    iservicecollection serviceconfiguration = configureservices();            iserviceprovider serviceprovider = serviceconfiguration.buildserviceprovider();     ibuscontrol buscontrol = createservicebus(serviceprovider);      iservicecollection services = new servicecollection();     services.addsingleton<ibuscontrol>(buscontrol);           iserviceprovider servicebus = services.buildserviceprovider();

is possible this, need because createservicebus using first iserviceprovider, using dependancy injection why need 2 iserviceprovider because after want register buscontrol ibuscontrol

you can create factory method , warm in startup.cs.

services.addsingleton<ibuscontrol>(provider => createservicebus(provider));

and "warm" in configure method

public void configure(iappbuilder app, ibuscontrol bus) { }

or 

public void configure(iappbuilder app, ibuscontrol bus) {     app.services.getrequriedservice<ibuscontrol>(); }

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
