Dictionary
|
||||||
|
|
||||||
|
A szótár elempárok tárolására szolgál,
|
||||||
|
melyek közül egyik a kulcs, amely azonosítja az elempárt,
|
||||||
|
másik az érték, minden kulcs egyedi.
|
||||||
|
|
||||||
|
Gyakorlatilag a szótár úgy viselkedik,
|
||||||
|
mint egy lista, de az elemek indexe itt tetszőleges típusú lehet pl.: szöveg.
|
||||||
|
|
||||||
|
Konstruktora generikus, paraméter nélküli:
|
||||||
|
Dictionary<TKey, TValue>(): létrehoz egy szótárt, ahol Tkey a kulcs TValue az érték típusa.
|
||||||
|
|
||||||
|
A szótár elemei a [] operátorral érhetőek el.
|
||||||
|
A szótárat foreach ciklussal lehet végig olvasni, amellyel a szótárból KeyValuePair<Tkey, Tvalue>
|
||||||
|
típusú elemeket kapunk. Ezek Key value mezői adják a megfelelő kulcs és érték párokat.
|
||||||
|
|
||||||
|
Fő metódusai:
|
||||||
|
Add(TKey, TValue)
|
||||||
|
Bool ContainsKey(TKey)
|
||||||
|
Bool ContainsValue(TValue)
|
||||||
|
bool Remove(Tkey) // ha sikeres a művelet akkor true
|
