well discovered extension methods, extension methods allow extending methods , functionality existing type without needing change code : here // extending using extension methods static class myextensionmethods { public static int negate(this int value) { return -value; } } static void main(string[] args) { //using extension method int i2 = 53; console.writeline(i.negate()); } my question : is possible same thing object, example add int id form, can : form frm = new form(); frm.id = 2; yes, can create extension methods on type of class want. however, example not method property , cannot create extension properties. the following valid: static class formextensions{ public static void setid(this form form, int someid) { // someid here } } // call this: form frm = new form(); frm.setid(2);

my xml looks this: <names> <goodnames> <name>alpha</name> <name>beta</name> </goodnames> <badnames> <name>blabla</name> </badnames> </names> now trying value of child nodes belong goodnames or badnames. code i've tried far this: var goodnames = el in doc.root.elements("goodnames") select el.element("name"); unfortunately, returns first element, in case alpha. however, i'd name elements. if want names need this: var allnames = e in doc.root.descendants("name") select e.value; if want names or bad names, try kind of thing: var goodnames = el in doc.root.elements("goodnames") n in el.elements("name") select n.value;

assume have c++ class this: class container { private: union { foo* foo; bar* bar; } mptr; }; this class constructed on stack. i.e. won't new ed, can't declare zeroing operator new . can use initializer in constructor set mptr nullptr somehow? container() : mptr(nullptr) { } does not compile. not adding dummy union member of type nullptr_t . container() : mptr.foo(nullptr) { } doesn't compile, either. use aggregate initialization, example: container() : mptr { nullptr } { } i don't posting links, here run through of technique.

i'm working on block cipher algorithm , requirements state 128 bit key state (stored big endian) needs shifted 25 bits right. key state must 2 longs. here's latest attempt @ figuring out. shifted both upper , lower halves of key right 25 bits, stored new values in new longs rotated keys left 39 bits. xor'd first new upper key second lower key , stored in upper half of key, , did same other 2 shifted keys stored in lower half of key. idea behind being needs have 25 shifted bits @ front of upper half of key. long rotkeyupper = keyupper >> 25; long rotkeylower = keylower >> 25; long rotkeyupper2 = keyupper << 39; long rotkeylower2 = keylower << 39; keyupper = rotkeyupper ^= rotkeylower2; keylower = rotkeyupper2 ^= rotkeylower; keyupper |= keylower; does make sense? edit: yes did mean rotate. , clarify, "rotkeyupper" , "rotkeylower" longs store rotated bits - keyupper , keylower 2 longs actual key - sorry confusion.
