Remarques
Chaque clé doit implémenter l’interface IComparable pour pouvoir effectuer des comparaisons avec toutes les autres clés de l’objet SortedList . Les éléments sont triés en fonction de l’implémentation IComparable de chaque clé ajoutée à .SortedList
La capacité d’un SortedList objet est le nombre d’éléments que le SortedList peut contenir. À mesure que des éléments sont ajoutés à un SortedList, la capacité est automatiquement augmentée en fonction des besoins en réaffectant le tableau interne.
Si la taille de la collection peut être estimée, la spécification de la capacité initiale élimine la nécessité d’effectuer un certain nombre d’opérations de redimensionnement tout en ajoutant des éléments à l’objet SortedList .
Ce constructeur est une O(1)
opération.

Remarques
Les éléments sont triés en fonction de l’implémentation spécifiée IComparer . Si le comparer
paramètre est null
, l’implémentation IComparable de chaque clé est utilisée ; par conséquent, chaque clé doit implémenter l’interface IComparable pour pouvoir effectuer des comparaisons avec toutes les autres clés de l’objet SortedList .
La capacité d’un SortedList objet est le nombre d’éléments que le SortedList peut contenir. À mesure que des éléments sont ajoutés à un SortedList, la capacité est automatiquement augmentée en fonction des besoins en réaffectant le tableau interne.
Si la taille de la collection peut être estimée, la spécification de la capacité initiale élimine la nécessité d’effectuer un certain nombre d’opérations de redimensionnement tout en ajoutant des éléments à l’objet SortedList .
Ce constructeur est une O(1)

Remarques
Chaque clé doit implémenter l’interface IComparable pour pouvoir effectuer des comparaisons avec toutes les autres clés de l’objet SortedList . Les éléments sont triés en fonction de l’implémentation IComparable de chaque clé ajoutée à .SortedList
Un Hashtable objet est un exemple d’implémentation IDictionary qui peut être passée à ce constructeur. Le nouvel SortedList objet contient une copie des clés et des valeurs stockées dans .Hashtable
La capacité d’un SortedList objet est le nombre d’éléments que le SortedList peut contenir. À mesure que des éléments sont ajoutés à un SortedList, la capacité est automatiquement augmentée en fonction des besoins en réaffectant le tableau interne.
Si la taille de la collection peut être estimée, la spécification de la capacité initiale élimine la nécessité d’effectuer un certain nombre d’opérations de redimensionnement tout en ajoutant des éléments à l’objet SortedList .
Ce constructeur est une O(n)
opération, où n
est le nombre d’éléments dans d
.

Remarques
Les éléments sont triés en fonction de l’implémentation spécifiée IComparer . Si le comparer
paramètre est null
, l’implémentation IComparable de chaque clé est utilisée ; par conséquent, chaque clé doit implémenter l’interface IComparable pour pouvoir effectuer des comparaisons avec toutes les autres clés de l’objet SortedList .
La capacité d’un SortedList objet est le nombre d’éléments que le SortedList peut contenir. À mesure que des éléments sont ajoutés à un SortedList, la capacité est automatiquement augmentée en fonction des besoins en réaffectant le tableau interne.
Si la taille de la collection peut être estimée, la spécification de la capacité initiale élimine la nécessité d’effectuer un certain nombre d’opérations de redimensionnement tout en ajoutant des éléments à l’objet SortedList .
Ce constructeur est une O(n)
opération, où n
est capacity
.
