c# - Reading XML nested node values -

-

having issue grabbing values in xml file structure followed

<configuration>     <settings>        <add key="folder" value = "c:\...." />     </settings> </configuration>

i want able read value folder.

string val = string.empty;          foreach (xelement element in xelement.load(file).elements("configuration"))         {             foreach (xelement element2 in element.elements("settings"))             {                 if (element2.name.equals("folder"))                 {                     val = element2.attribute(key).value;                     break;                 }             }         }          return val;

the name of element isn't folder... that's value of key attribute. note you've used xelement.load, element is configuration element - asking elements("configuration") give empty collection. either load xdocument instead, or assume you're on configuration element , beneath settings.

i think want:

return xelement.load(file)                .elements("settings")                .elements("add")                .where(x => (string) x.attribute("key") == "folder")                .select(x => (string) x.attribute("value"))                .firstordefault();

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
