SortedList()	初始化 SortedList 类的新实例，该实例为空、具有默认初始容量并根据 IComparable 接口（此接口由添加到 SortedList 对象中的每个键实现）进行排序。
SortedList(IComparer)	初始化 SortedList 类的新实例，该实例为空、具有默认初始容量并根据指定的 IComparer 接口进行排序。
SortedList(IDictionary)	初始化 SortedList 类的新实例，该实例包含从指定字典复制的元素、具有与所复制的元素数相同的初始容量并根据由每个键实现的 IComparable 接口排序。
SortedList(Int32)	初始化 SortedList 类的新实例，该实例为空、具有指定的初始容量并且根据 IComparable 接口（此接口由添加到 SortedList 对象的每个键实现）进行排序。
SortedList(IComparer, Int32)	初始化 SortedList 类的新实例，该实例为空、具有指定的初始容量并根据指定的 IComparer 接口排序。

注解

每个键都必须实现 IComparable 接口，才能与对象中的每个 SortedList 其他键进行比较。元素根据 IComparable 添加到 SortedList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。当元素添加到时 SortedList，容量会根据需要通过重新分配内部数组自动增加。

如果可以估计集合的大小，则指定初始容量就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。

注解

元素根据指定的 IComparer 实现进行排序。 comparer如果参数为 null，则IComparable使用每个键的实现;因此，每个键都必须实现 IComparable 接口，以便能够与对象中的每个SortedList其他键进行比较。

对象的容量 SortedList 是可以容纳的元素 SortedList 数。当元素添加到时 SortedList，容量会根据需要通过重新分配内部数组自动增加。

如果可以估计集合的大小，则指定初始容量就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。

注解

每个键都必须实现 IComparable 接口，才能与对象中的每个 SortedList 其他键进行比较。元素根据 IComparable 添加到 SortedList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。当元素添加到时 SortedList，容量会根据需要通过重新分配内部数组自动增加。

如果可以估计集合的大小，则指定初始容量就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 为 initialCapacity。

适用于

SortedList(IComparer, Int32)

Source:: SortedList.cs

Source:: SortedList.cs

Source:: SortedList.cs

初始化 SortedList 类的新实例，该实例为空、具有指定的初始容量并根据指定的 IComparer 接口排序。

public:
 SortedList(System::Collections::IComparer ^ comparer, int capacity);

public SortedList (System.Collections.IComparer comparer, int capacity);

public SortedList (System.Collections.IComparer? comparer, int capacity);

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

Public Sub New (comparer As IComparer, capacity As Integer)

参数

comparer: IComparer

在对键进行比较时使用的 IComparer 实现。

- 或 -

null，使用每一个键的 IComparable 实现。

capacity: Int32

SortedList 对象可包含的初始元素数。

例外

ArgumentOutOfRangeException

capacity 小于零。

OutOfMemoryException

没有足够的可用内存来创建具有指定 capacity 的 SortedList 对象。

注解

对象的容量 SortedList 是可以容纳的元素 SortedList 数。当元素添加到时 SortedList，容量会根据需要通过重新分配内部数组自动增加。

如果可以估计集合的大小，则指定初始容量就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 为 capacity。

适用于

SortedList(IDictionary, IComparer)

Source:: SortedList.cs

Source:: SortedList.cs

Source:: SortedList.cs

初始化 SortedList 类的新实例，该实例包含从指定字典复制的元素、具有与所复制的元素数相同的初始容量并根据指定的 IComparer 接口排序。

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

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

要复制到新 IDictionary 对象的 SortedList 实现。

comparer: IComparer

在对键进行比较时使用的 IComparer 实现。

- 或 -

null，使用每一个键的 IComparable 实现。

例外

ArgumentNullException

d 为 null。

InvalidCastException

comparer 为 null，且 d 中的一个或多个元素未实现 IComparable 接口。
