Comentários

Cada chave deve implementar a IComparable interface para ser capaz de comparações com todas as outras chaves do SortedList objeto. Os elementos são classificados de acordo com a IComparable implementação de cada chave adicionada ao SortedList.

A capacidade de um SortedList objeto é o número de elementos que o SortedList pode conter. À medida que os elementos são adicionados a um SortedList, a capacidade é automaticamente aumentada conforme exigido pela realocação da matriz interna.

Se o tamanho da coleção puder ser estimado, especificar a capacidade inicial eliminará a necessidade de executar várias operações de redimensionamento ao adicionar elementos ao SortedList objeto .

Esse construtor é uma O(1) operação.

Comentários

Os elementos são classificados de acordo com a implementação especificada IComparer . Se o comparer parâmetro for null, a IComparable implementação de cada chave será usada; portanto, cada chave deverá implementar a IComparable interface para ser capaz de comparações com todas as outras chaves do SortedList objeto.

A capacidade de um SortedList objeto é o número de elementos que o SortedList pode conter. À medida que os elementos são adicionados a um SortedList, a capacidade é automaticamente aumentada conforme exigido pela realocação da matriz interna.

Se o tamanho da coleção puder ser estimado, especificar a capacidade inicial eliminará a necessidade de executar várias operações de redimensionamento ao adicionar elementos ao SortedList objeto .

Esse construtor é uma O(1) operação.

Comentários

Cada chave deve implementar a IComparable interface para ser capaz de comparações com todas as outras chaves do SortedList objeto. Os elementos são classificados de acordo com a IComparable implementação de cada chave adicionada ao SortedList.

Um Hashtable objeto é um exemplo de uma implementação IDictionary que pode ser passada para esse construtor. O novo SortedList objeto contém uma cópia das chaves e valores armazenados no Hashtable.

A capacidade de um SortedList objeto é o número de elementos que o SortedList pode conter. À medida que os elementos são adicionados a um SortedList, a capacidade é automaticamente aumentada conforme exigido pela realocação da matriz interna.

Se o tamanho da coleção puder ser estimado, especificar a capacidade inicial eliminará a necessidade de executar várias operações de redimensionamento ao adicionar elementos ao SortedList objeto .

Esse construtor é uma O(n) operação, em que n é o número de elementos em d.

Comentários

Cada chave deve implementar a IComparable interface para ser capaz de comparações com todas as outras chaves do SortedList objeto. Os elementos são classificados de acordo com a IComparable implementação de cada chave adicionada ao SortedList.

A capacidade de um SortedList objeto é o número de elementos que o SortedList pode conter. À medida que os elementos são adicionados a um SortedList, a capacidade é automaticamente aumentada conforme exigido pela realocação da matriz interna.

Se o tamanho da coleção puder ser estimado, especificar a capacidade inicial eliminará a necessidade de executar várias operações de redimensionamento ao adicionar elementos ao SortedList objeto .

Esse construtor é uma O(n) operação, em que n é initialCapacity.

Parâmetros

comparer
IComparer

A implementação de IComparer a ser usada ao comparar chaves.

- ou -

null para usar a implementação de IComparable de cada chave.

capacity

Exceções

ArgumentOutOfRangeException

capacity é menor que zero.

OutOfMemoryException

Não há memória suficiente disponível para criar um objeto SortedList com o capacity especificado.

Comentários

Os elementos são classificados de acordo com a implementação especificada IComparer . Se o comparer parâmetro for null, a IComparable implementação de cada chave será usada; portanto, cada chave deverá implementar a IComparable interface para ser capaz de comparações com todas as outras chaves do SortedList objeto.

A capacidade de um SortedList objeto é o número de elementos que o SortedList pode conter. À medida que os elementos são adicionados a um SortedList, a capacidade é automaticamente aumentada conforme exigido pela realocação da matriz interna.

Se o tamanho da coleção puder ser estimado, especificar a capacidade inicial eliminará a necessidade de executar várias operações de redimensionamento ao adicionar elementos ao SortedList objeto .

Esse construtor é uma O(n) operação, em que n é capacity.

Comentários

Os elementos são classificados de acordo com a implementação especificada IComparer . Se o comparer parâmetro for null, a IComparable implementação de cada chave será usada; portanto, cada chave deverá implementar a IComparable interface para ser capaz de comparações com todas as outras chaves do SortedList objeto.

Um Hashtable objeto é um exemplo de uma implementação IDictionary que pode ser passada para esse construtor. O novo SortedList objeto contém uma cópia das chaves e valores armazenados no Hashtable.

A capacidade de um SortedList objeto é o número de elementos que o SortedList pode conter. À medida que os elementos são adicionados a um SortedList, a capacidade é automaticamente aumentada conforme exigido pela realocação da matriz interna.

Se o tamanho da coleção puder ser estimado, especificar a capacidade inicial eliminará a necessidade de executar várias operações de redimensionamento ao adicionar elementos ao SortedList objeto .

Esse construtor é uma O(n) operação, em que n é o número de elementos em d.
