c# - Custom authorize and authentication using operationcontext in wcf -


i created wcf service below custom authentication

public class restauthorizationmanager: serviceauthorizationmanager     {             protected override bool checkaccesscore(operationcontext operationcontext)         {             //extract authorization header, , parse out credentials converting base64 string:               var authheader = weboperationcontext.current.incomingrequest.headers["authorization"];              if ((authheader != null) && (authheader != string.empty))             {                 var svccredentials = system.text.asciiencoding.ascii                     .getstring(convert.frombase64string(authheader.substring(6)))                     .split(':');                 var user = new                 {                     name = svccredentials[0],                     password = svccredentials[1]                 };                 if ((user.name == "1" && user.password == "1"))                 {                     //user authrized , originating call proceed                       string role = getfromdatabase(user.name);                     if(role==?????????)                     return true;                 }                 else                 {                     //not authorized                       return false;                 }             }             else             {                  throw new webfaultexception(httpstatuscode.unauthorized);             }         }     }

as can see check username , password ,if result true role database string role = getfromdatabase(user.name);.

but want check operation role user role.i don't know how can access operation role [principalpermission(securityaction.demand, role = "admin")] here admin ,in checkaccesscore function?

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 <...
