注解

每个键必须实现 IComparable 接口才能与对象中的其他 SortedList 每个键进行比较。这些元素根据 IComparable 添加到 SortedList该元素的每个键的实现进行排序。

对象的容量 SortedList 是可以容纳的元素 SortedList 数。随着元素添加到 a SortedList，重新分配内部数组，容量会自动增加。

如果可以估计集合的大小，则指定初始容量无需在向对象添加元素 SortedList 时执行大量调整大小操作。

此构造函数是一个 O(1) 操作。

适用于

SortedList(IComparer)

初始化为空的 SortedList 类的新实例，具有默认的初始容量，并根据指定的 IComparer 接口进行排序。

public:
 SortedList(System::Collections::IComparer ^ comparer);

public SortedList(System.Collections.IComparer comparer);

new System.Collections.SortedList : System.Collections.IComparer -> System.Collections.SortedList

Public Sub New (comparer As IComparer)

参数

comparer: IComparer

IComparer比较键时要使用的实现。

-或-

null IComparable使用每个密钥的实现。

InvalidCastException

一 d 个或多个元素未实现 IComparable 接口。

注解

每个键必须实现 IComparable 接口才能与对象中的其他 SortedList 每个键进行比较。这些元素根据 IComparable 添加到 SortedList该元素的每个键的实现进行排序。

对象 Hashtable 是可传递给此构造函数的 IDictionary 实现的示例。新 SortedList 对象包含存储在中的 Hashtable键和值的副本。

对象的容量 SortedList 是可以容纳的元素 SortedList 数。随着元素添加到 a SortedList，重新分配内部数组，容量会自动增加。

如果可以估计集合的大小，则指定初始容量无需在向对象添加元素 SortedList 时执行大量调整大小操作。

此构造函数是一个 O(n) 操作，其中 n 元素的数目 d。

注解

对象的容量 SortedList 是可以容纳的元素 SortedList 数。随着元素添加到 a SortedList，重新分配内部数组，容量会自动增加。

如果可以估计集合的大小，则指定初始容量无需在向对象添加元素 SortedList 时执行大量调整大小操作。

此构造函数是一个O(n)操作，其中 n 。capacity

适用于

SortedList(IDictionary, IComparer)

初始化包含从指定字典复制的元素的类的新实例 SortedList ，其初始容量与复制的元素数相同，并根据指定的 IComparer 接口进行排序。

public:
 SortedList(System::Collections::IDictionary ^ d, System::Collections::IComparer ^ comparer);

public SortedList(System.Collections.IDictionary d, System.Collections.IComparer comparer);

new System.Collections.SortedList : System.Collections.IDictionary * System.Collections.IComparer -> System.Collections.SortedList

Public Sub New (d As IDictionary, comparer As IComparer)

参数

d: IDictionary

IDictionary要复制到新SortedList对象的实现。

comparer: IComparer

IComparer比较键时要使用的实现。

-或-

null IComparable使用每个密钥的实现。

例外

ArgumentNullException

d 是 null。

InvalidCastException

comparer 是 null，并且其中 d 一个或多个元素未实现 IComparable 接口。
